This study investigated flora and vascular plants area around Buyongdae where include optimum view point Okyeonjeongsa and Gyeomamjeongsa in Hahoe Village, Andong. Based on the findings, the aim of results was attempted to suggest the management plan of the vegetation area around Buyongdae which designated UNESCO World cultural heritage and folk village in Korea. The results of the study is as the following. All flora of this site, Buyongdae in Andong, were 301 taxa; 89 families, 217 genera, 251 species, 1 subspecies, 38 varieties and 11 forms. Vegetation of each of areas in site was classified Pinus densiflora as representative forest around Buyongdae, Quercus variabilis forest around Gyeomamjjeongsa and Koelreuteria paniculata forest in river cliff of Buyongdae. The 14 taxa(Polygala tenuifolia, Koelreuteria paniculata, and others) as the rare plants and the 7 taxa(Weigela subsessilis, and others) as endemic species were recorded in the surveyed site among the whole flora. The specific plants which is categorized to degree by the Ministry of Environment appeared as 32 taxa; degree IV was 4 species; Polygala tenuifolia, etc. and degree III was 10 species; Hypodematium glandulosopilosum, Pyrrosia petiolosa, etc. and degree I was 13 species; Hemiptelea davidii, Zizyphus jujuba var. jujuba, etc. Also, the 11 taxa were recorded in limestone area as the chamaephyte; Hypodematium glandulosopilosum, Celtis koraiensis, Siphonostegia chinensis, Artemisia gmelini, and others. The naturalized plants recorded as 25 taxa; Viola arvensis, Erechtites hieracifolia, etc. and invasion of Sicyos angulatus which is ecosystem disturbing plants. The naturalization rate(NR) was 8.3% and the urbanization index(UI) was 7.8% by field survey. For recovery of indigenous to traditional vegetation landscape in Buyongdae, Pinus rigida of upper-growth and Alnus sibirica of middle-growth need thinning. In addition, the site demands both sustainable management through long-term monitering and gradual elimination method for the naturalized plants including Sicyos angulatus where found in Kyumamjeongsa. Particularly, intentional planting for decoration and cultivation around Hwachunseowon, Helianthus tuberosus must be substitute with the native plants. Meanwhile, Polygala tenuifolia is potently demanded preventing habitate, confirming additional habitate, seed securing and preservation of gene resource internally or externally. Koelreuteria paniculata; denoting feature of river cliff, including Hypodematium glandulosopilosum, Siphonostegia chinensis, Zizyphus jujuba var. jujuba, Pyrrosia petiolosa, and Celtis koraiensis, also need an assertive preservation. Futhermore, Wisteria floribunda for. floribunda, located around Galmo rock to Chunggil course, remained by colonizing form, need preservation and observation for a while. Beside that, the information boards are required to educate visiting user about safe regulations on the narrow way in rock hill.

This study was to suggest cultural landscape preservation, value creation, as well as utilization plan to help landscape development of Hahoe village by identify the existence of Okyeonsipyeong(玉淵十詠) natural features, which were set around Buyongdae(芙蓉臺) in Hahoe Village by Seoae(西崖) Ryu, Seongryong(柳成龍), and understanding their characteristics and meanings of natural features and meanings. Based on the writings of "Okyeonseodanggi" and "Okyeonsipyeong", the major results of this study are as belows. 'Okyeon(玉淵)' letters carved on the rocks, also known as the name of pavilion in Okyeonjeongsa(玉淵精舍), is the center of Okyeonsipyeong that symbolizes the enlightenment of clean noble man, as well as the symbolic locational expression of studying room. One of Okyeonsipyeong, 'Wansimjae', is assumed to be the name from the combination of two Buddhist names, 'Wanjeok(玩寂)' and 'Seshim(洗心)', 'Dangho(堂號)', lined on both sides with Wonlakjae, the residence of Seoae, as the center. Wansimjae is after all the natural feature indicating the overall Okyeonjeongsa as the core of Okyeonsipyeong with west edge Gyeomamjeongsa(謙巖精舍). Among ten Okyeonsipyeong natural features, Wansimjae(玩心齋), Ganjukmun(看竹門), Gyeomamsa(謙菴舍), Dalgwandae(達觀臺), Ssangsongae(雙松厓), and Dohwacheon (桃花遷) are on the right side of the stairway from Okyeonjeongsa to Gyeomamjeongsa, while Chuwoldam(秋月潭), Neungpadae(凌波臺), Gyeseonam(繫船巖), and Jijuam(砥柱巖) are on the road to the cliff under river cliff in Buyongdae as well as to the dock, and all are located within 500m radius close and diameter area. As the results of lexeme and context analyses of Okyeonsipyeong poet, they are mainly about Confucian teachings symbolizing the constancy of the classical scholar including ego becoming one with the nature and back to the nature, unworldliness and farsighted view, transcendence and seclusion, as well as integrity spirit. In Dohwacheon and Gyeomamsa poets, there is Tao characteristics and brotherhood that pursue fairylands such as Mooreungdowon(武陵桃源). To create tourism brand and landscape of Okyeonsipyeong, it is necessary to prepare storytelling plans including the letters carved on the rocks introduction in Buyongdae area, and also synopsis of the Silgyeongsusang musical, 'Buyongjiae(芙蓉之愛)' that is related to 10 natural features. In addition, the related plans of the experience road from Gyeseonam, which is the boat stop in Buyongdae, to Ganjukmun of Okyeonjeongsa, and again to viewing routes on the stairways to Gyeomamjeongsa using boats are necessary. For preliminary preservation and maintenance plans, the safety of the stairway from Okyeonjeongsa to Gyeomamjeongsa should be secured, the rock inscription should be preserved, landscape interpretation plates should be installed, trees and shrubs around Dohwacheon rock inscription should be removed, Dalgwandae letters carved on the rocks should be restored, and the bamboo forest outside Ganjukmun as well as Prunus persica plantation around Dohwacheon should be pointed out.

The rock-cut relief of two Buddhas seated side-by-side in Wonpungri is a large Buddha sculpture in relief on the side of a cliff in Wonpung-ri, Goesan. This Buddha sculpture is from the Buddhist scripture Sutra of the Lotus. <法華經> Two seated Buddhas statues were prevalent in the Balhae Kingdom, but this was not popular in Silla and Goryeo. In the main text, the time that the two seated Buddhas in Wonpung-ri was created is identified as being during the 10th century. King Gwangjong created a Buddha statue for political purposes. The relief of two seated Buddha image carved on a cliff is located on an important traffic route over the Sobaek Mountain Range. After King Gwangjong took the throne, he paid close attention to the reigning powers of Jincheon and Cheongju because the people of Jincheon and Cheongju were engaged in a power struggle against Gwangjong. The huge relief of two seated Buddhas statue shows the authority of King Gwangjong. In particular, the people of Jincheon and Cheongju had to see this Buddha statue when crossing the Sobaek Mountain Range. The image contained in the relief of the two seated Buddhas features many characteristics of the sculpture style of the Balhae Kingdom. After the fall of Balhae, many of the Balhae people settled in Mungyeong. Balhae people from Mungyeong participated in the production of the relief of the two seated Buddhas. Through the relief of the two seated Buddhas, King Gwangjong wanted to show the people of Jincheon and Cheongju that the Balhae people were supporting him. The relief of two seated Buddhas reflects the historical situation of the King Gwangjong era in the late 10^th century and the style of sculpture.

Dokdo has historical and political meaning in relation to the territorial problems with Japan. The area can be the main factor to explain the formation and development process of East-Sea as exposure volcanic island at East-Sea with Ulreong-island. Accordingly, it also has an important meaning of physical geography aspects In this research, it is perceived the geomorphological development process of slope due to the salt weathering which is considered as the most important factor to understand whole geomorphology of Dokdo. And researched how a geomorphology of this sort affects to animal and plants. The peculiar geomorphology is tafoni which is a weathering geomorphology and one of the remarkable geomorphology in preservation of Dokdo. Tafoni at west part of Dongdo is distributed intensively near shoreline which is composed tuff. The shape of tafoni is mainly massive, circle and oval in Massive tuff breccia layer also is formed toward horizontality bedding direction in Bedded lapilli tuff. Tafoni in Dokdo is constituted after middle of Holocene. This fact can be proved by ranging at surface of sea-cliff which is formed wave erosion after middle of Holocene sea-level reaching to present level. Tafoni is also the most contribute factor of geomorphology dissection of Dokdo as it is eroded the bed rock with salt weathering. In bottom part of tafoni it has an important function for habitat of birds. Herbaceous plants are on it. To procrastinate of bed rock dissection by growth of Tafoni, conservation of vegetation and soil are most important factor.

Mt. Mudeung is located in Gwangju city, Damyang-Gun, Hwasun-Gun and its round form give us the mood of soft and rich. Its location is $126^{\circ}06'-127^{\circ}01'E$ and $35^{\circ}06'-35^{\circ}10'N$ and its highest peak is Cheonwang-bong with the height of 1,187 m. The Gwangju city is located in the West of Mt. Mudeng and the mountain range with a small basin in its East. The pavilion such as the Soswaewon, Songganjeong, Sigyongjeong are distributed along the stream in the north of Mt. Mudeung. The mountain is formed from the volcanic activity, Gwangju cauldron during the Cretaceous. The top part of Mt. Mudeung is composed of dark gray quartz-andesite and its K-Ar whole rock age is $48.1{\pm}1.7Ma$. The composition of the north area, where the Wonhyosa temple is located, is micrographic granite, whereas the composition of south area is rhyolite mainly. The main ridge of Mt. Mudeung runs from North, starting from the Bukbong, to south, passing Cheonwangbong, Jangbuljae and ending Anyangsan. Geologic feature of the mountain includes volcanic landform, mountaineous landform, and stream landform. The Seosukdae, Ipseokdae, Gyubongam, which are main ridges and formed from volcanic activity, are composed of mainly columnar joint. Saeinbong and Majipbong in the south-west are composed of mainly cliff and dome. The typical erosion landform of the mountain has three different types of the weathering-cave, each of which reflect the property of the original rock. Four different area of wide block stream, they makes the geological feature of spring-water, though its scale is small compared to that of water fall.

The rock-carved Buddha statue at Dosolam (Korea Treasure No. 1200) of the Seonunsa temple in Gochang is unique style sculptured on natural rock cliff of 13.0m height. The Buddha statue is composed of volcanic complex with tuff, dacitic tuff breccia, tuff bereccia and lithic tuff. Especially, the Buddha statue is characterized by hydrothermal alteration and fragmentation on the upper and lower part. As a result of damage diagnosis, exfoliation and detachment of physical weathering are high of 11.3% and 9.3%, respectively. Infrared thermography analysis, exfoliation and micro-cracks occurred in the measuring parts that have not been confirmed by naked eyes. Chemical index of alteration and weathering potential index of host rock for the Buddha statue are 55.16 to 64.01 and 6.14 to 9.92 which are represented within highly weathering degree. In surface, dark black, reddish brown and white discoloration are observed prominently in the lower. Brown discoloration 6.9% is highest. According to the P-XRF measurements, high concentration of Fe in common, in part of dark black discoloration was Mn, white and brown discoloration in part of S and Ca content were higher. Biological weathering that yellowish brown and dark gray crustoes lichenes appeared by 20.8% and 13.3%, respectively. Therefore, comprehensive deterioration rate of Buddha statue show physical damage by 21.2%, discoloration for inorganic contaminants by 10.8% and biological damage by 39.4%. Ultrasonic velocity measurement carried out of Buddha statue on the surface by 555 points. Measured value of ultrasonic velocity was about 2,273m/s(1,067 to 3,215m/s, and weathering coefficient is 0.5(0.4 to 0.8) that progress on MW(moderately weathered) to HW(highly weathered) grade of rocks.

This study conducted an analysis of plant species composition and vegetation at sea cliffs of the uninhabited islets off Ganghwa-gun by applying discontinuous classification method & continuous ordination method of species composition table by correlation. The analysis results are as follows: First, the plant showing the highest appearance frequency was Parthenocissus tricuspidata Planch.(58.3%), followed by Carpinus coreana Nak., Viburnum carlesii Hemsl. and Kalopanax septemlobus Koidz.(37.5%,respectively). As for a plant community, it was found that it consisted of Quercus mongolica community, Tilia mandshurica community, Carpinus coreana community, Sorbus alnifolia community and Pinus thunbergii community; as for the community distribution classified by individual islet, it was revealed that Quercus mongolica community appeared at Sosongdo and Bunjido; Tilia mandshurica community at Sosongdo and Daesongdo; Carpinus coreana community appeared at Woodo, Suribong and Bido; Sorbus alnifolia community at Susido, Sosongdo and Daesongdo, and Pinus thunbergii community at Seokdo and Woodo, respectively. The plant similarity classified by uninhabited islet was found to be the highest at Sosongdo and Daesongdo. This research judged the reason why the typical grassland community of coastal cliffs did not join these islets to be environmental conditions of rock landform where there exists almost no surface soil at most sea cliffs; thus, more detailed study on this was required.

Dangsanbong volcano, which is located on the coast of the western promontory of Cheju Island, occurs in such a regular pattern on the sequences which represent an excellent example of an eruptive cycle. The volcano comprises a horseshoe-shaped tuff cone and a younger nested cinder cone on the crater floor, which are overlain by a lava cap at the top of the cinder cone, and wide lava plateau in the moat between two cones and in the northern part. The volcanic sequences suggest volcanic processes that start with Surtseyan eruption, progress through Strombolian eruption and end with Hawaiian eruption, and then are followed by rock fall from sea cliff of the tuff cone and by air fall from another crater. It is thought that the eruptive environments of the tuff cone could be mainly emergent because the present cone is located on the coast, and standing body of sea water could play a great role. It is thought that the now emergent part of the tuff cone was costructed subaerially because there is no evidence of marine reworking. The emergent tuff cone is characterized by distinctive steam-explosivity that results primarily from a bulk interaction between rapidly ascending magma and external water. The sea water gets into the vent by flooding accross or through the top or breach of northern tephra cone. Dangsanbong tuff cone was constructed from Surtseyan eruption which went into with tephra finger jetting explosion in the early stage, late interspersed with continuous upruch activities, and from ultra-Surtseyan jetting explosions producting base surges in the last. When the enclosure of the vent by a long-lived tephra barrier would prevent the flooding and thus allow the vent to dry out, the phreatomagmatic activities ceased to transmit into magmatic activity of Strombolian eruption, which constructed a cinder cone on the crater floor of the tuff cone Strombolian eruption ceased when magma in the conduit gradually became depleted in gas. In the Dangsanbong volcano, the last magmatic activity was Hawaiian eruption which went into with foundation and effusion of basalt lava.

Gaesung city of North Korea is meaningful because of the development of Gaesung industrial complex as a peace-building project and economical cooperation works between South Korea and North Korea. This article presents the characteristics of natural landscape of Gaesung through geographical names. This research was studied by literature analysis of North Korea, depth interview of North Korean labour and refugees, and second times fieldwork. The main results of this study are as follows. Firstly, the mountain landscape of Geasung revealed on geographical names characterized mountainousness and round shape. Especially, the places where are enclosed by mountain and streams are foggy and rocky. Next the landscape of stream characterizes sandy, unstable, and tidal river. Thirdly the fauna and flora which are reflected on geographical names are hawk, snake, tiger, homed owl, snapping turtle, chestnut tree, pine tree, pear tree, zelkova tree, and willow etcetera. The environmental conditions of habitation of these are similar to the natural environment of Gaesung. Besides, the geographical names related to soil distributed in northern mountain area of Geasung. The place names implicated cliff located on the riverside. In addition to this, the geographical name of 'Bul' implicated plain distributed in the riverside of 'Seoam' which a branch stream of 'Sacheo'. And the place names related rock located in place enclosed by mountain, river, and village. In cnclusion, Gaesung is more important to us as the Gaesung industrial complex and tourism development. But the fundamental research on Gaesung is a few because Gaesung belongs to North Korea. Therefore, this research will be useful for the control and management of Gaesung in the future.

Satae cheon, a tributary of the Suip cheon in Yanggu, Gangwon province, is an international river extended to North Korea. Most of drainage basin area of the river was the fierce battle field during the Korean War(1950-1953) and hard to access as it located between the MDL(Military Demarcation Line) and the CCZ(Civilian Control Zone: about 10km south from MDL). By the restriction of access to the sites, most of natural landscape have been well conserved except limited use for military activities. Even the landfoms in that area were not studied, except the government's heritage reports. Satae Cheon's channel follows the Imdang fault line(N-S) to Satae-ri and flow to west to the Dutayeon area. The river meanders along geological structure or weak line at the Dutayeon area. The meandering channel was shorten by the meander cut which linked the thalweg line of meander loop ant the meander neck. As a result of this cut, the river cliff formed by the Satae cheon became the part of newly formed channel bed and the S-forms are formed. After the channel route stabilized, channel incised the rock with large potholes and undulating walls were formed. The channel width changes from 1m to 10m with restriction of the undulating walls, so this part can be regarded as inner channel or inner gorge. From the point of planar forms it also can be slot-type canyon.
