  • The biomass of Pinus densiflora stands burnt out by the 2005 Yangyang forest fire was estimated based on the grades of fire severity; light, moderate and heavy. In order to measure the post-fire ground biomass in kg/ha, the ground fuels including shrub layer were collected and weighted and the crown biomass was estimated using allometric regressions and leaf area index for dry weight of P. densiflora. The pre-fire biomass was assumed to be equal to that of non-damaged P. densiflora stands having the same characteristics. The results indicated that the forest fire burnt out fuels of stands; 3,693 kg/ha in the light-damaged, 8,724 kg/ha in the moderately-damaged, and 17,451 kg/ha in the heavily-damaged forest stands.

  • The chemical similarity of the magnetite-bearing amphiboltes of the Yangyang iron mine to mixtures of sedimentary pelites and limestone or dolomite and to the Gyeonggi para-amphibolites (So, 1974) is consistently indicated by all the chemical data of the rocks. Eight amphibolite samples were each analyzed for 18 elements, by wet chemical and emission spectroscopic methods, and these chemical data were compared with the para-amphibolites from the Gyeonggi metamorphic complex. Petrography and oxidation ratios were also considered.

  • To control forest fire effectively, it is necessary to understand forest fire behavior and relevance to forest fire environmental factors. In this paper, the behavior characteristics of the 2005 Yangyang forest fire were analyzed into the spread patterns and severity grades. The spread processes of the forest fire could be divided into two steps. At the first step, the fire ran fast to the east due to the strong west wind and then spreaded out in irregular direction. The maximum spread rate of the fire was 1.21km/hr and the mean was 0.65 km/hr. The result of the fire severity classification indicated that about $80\%$(1,110ha) of the whole study site was extremely burned and the remaining $15\%(211 ha)\;and\;5\%(61 ha)$ were damaged slightly and moderately respectively.

  • Coastal lagoons(Ssangho, Gapyeongri wetland, Gunggaeho and Yeomgaeho) distribute densely around Osan-ri, Yangyang-gun. While Ssangho with the representative lagoon group in the East Coast has maintained the lagoon conditions of water surface since it was formed during the Climax of transgression, the others were formed at the swale areas of sand beach. They vary considerably in area reduction rates and position variations during the 20th century, and the causes examined can be divided into natural, human and other factors. They result in the lagoon aggradation stage by geomorphic development, reclamation due to rapid industrialization and urban development during the 20th century, and lacks of understanding on values of small coastal lagoon or errors in mapping and lags of survey techniques. Therefore, the plans for lagoon restorations should be proceeded by the individual properties of lagoons. The restorations of Ssangho are recommended preferentially and it is desirable to restore to the lagoon conditions of 1920s when the influences of human were minimum.

  • The relationships between pine mushroom emergence and meteorological factors were analyzed with three years (from 2003 to 2005) of measurement data at Yangyang site, in order to evaluate the effect of micrometeorological environment on pine mushroom production. fine mushroom was daily monitored and collected in the survey area during the its producing period (approximately one month). Pine mushroom production was highest in 2005 with the meteorological conditions of high temperature and frequent rainfalls in October. The production was lowest in 2004 due to dry conditions from mid September to late October, The meterological factors related to humidity (i.e., relative humidity, soil water content, and precipitation) were better correlated than those related to temperature (i.e., air and soil temperature, soil heat flux and solar radiation) with pine mushroom production. However, all of the correlation coefficients were statistically insignificant with values ranging from 0.15 to 0.46. Such poor correlations may be attributed to various other environmental conditions (e.g., topography, soil, vegetation, other fungi, the relationship between pine mushroom and pine forest) affecting pine mushroom production. We found that a mycelium requires a stimulation of low temperature (of three-day moving average) below $19.5^{\circ}C$, in order to farm a mushroom primordium which grows to pine mushroom after 16 days from the stimulation. We also found that the pine mushroom production ended when the soil temperature (of three-day moving average) fell below $14.0^{\circ}C$.

  • This study, which starting from Yangyang Jukdo's topography formation and questioning revealed in landscape guide and landscape commentary board, is to sort out the characteristics of Jukdo natural landscape through literature research, field observation research and stakeholder interview as part of the proper recognition of Jokdo landscape and search for landscape resources, and pursued a review of nominations and criticism. The results of this study are summarized as follows. Yangyang Jukdo is an island named because it was full of blue bamboo. From before the first half of the 14th Century. to the middle of the 18th Century., there was a Gwanlan-pavilion to see the sea and the bamboo in the west. The time when the original island, the Jukdo, have been a land-tied island connected with the land by the tombolo formed by the erosion of the sand. It is located at the end of the 14th Century. and before the middle of the 18th Century. In Jukdo, colorful weathered terrains, coastal terrain, and structural terrain formed by long-time weathering are found. Among them, the type of weathering, the tafoni style and the gnamma style are the scenic landscapes with the key stories of legend and poetry that are brought to Jukdo. In addition, there are seven kinds of letters caved in the rocks in Jukdo. The rocks found on the coast, basketball cannons, shrines, and sutras are seen as shrouds based on a Taoist hermit motifs and style. In addition, it can be interred from the photography of "jeongssisejeog" that the souvenir of Jukdo was the family of Chogyejeong of mid 18th Century. In terms of observational geography and poetry, Jukdo has been handed down a great deal of missionary color with key motifs such as 'Jukdo-seongoo', 'Jukdo-Dolgooyoo', or 'Stone mortar of Taoist hermit' It is proved that the pearl which is called 'The stone of the Taoist hermit' is a porthole formed in a separate space rather than the topography of the geomorphology in terms of shape, size and function. Currently named Shun-tang is a product of the ridiculous 'naming' of interest. The present landscape guide and commentary is not only incompatible with the place of Jukdo, but also does not match the traditional cultural landscape. Future scenery information such as guide signs and commentary boards should be improved in the direction of positively highlighting the stories and motifs related to the present that are present in order to enhance the landscape identity of Yangyang Jukdo.

The Origin of Hajodae(河趙臺) in Yangyang(襄陽) and the Way of Enjoying Scenic Sites(名勝) According to the Landscape in Joseon Dynasty (조선시대 양양(襄陽) 하조대(河趙臺)의 유래와 경관에 따른 명승의 향유 방식)

  • This study aims to shed light on the cultural history of Hajodae(河趙臺) enjoyed by writers of the Joseon Dynasty by analyzing the origin and the contents of the landscape based on the literature materials of Hajodae in Yangyang(襄陽). The results of the study are as follows. First, Hajodae is a space that is said to have been visited by Ha Ryun(河崙) and Jo Jun(趙浚). However, since this story has not been confirmed in the literature, various opinions coexisted in history. Jo Wi-Han(趙緯韓) quoted the opinions of aged people who lived in Yangyang, saying that it could be Jo In-Byeok(趙仁壁), not Jo Jun(趙浚), and Jo Deok-Rin(趙德鄰) recorded it as "遐眺臺", which means "a stand for a distance view." There is a need to clearly present the origin of Hajodae by revealing the literary authority. Second, Hajodae was talked about as the best scenic site in Gwandong(關東) in the middle of the Joseon Dynasty. during the mid-Joseon Dynasty. The writers of the time mentioned Hajodae as one of the best scenic sites in Gwandong, which soon became a symbol of Yangyang. These records of Hajodae show a relatively decreasing trend entering the late Joseon Dynasty. It is believed to be the result of the slight degrading in the status of Hajodae as the Eight Views of Gwandong were established and Naksansa Temple(洛山寺) gained fame. Third, the writers of Joseon enjoyed the scenic sites through various landscapes of Hajodae. The open terrain on three sides allowed a sea view and provided an opportunity to develop a great spirit or to reflect on oneself. On the other hand, the strange rock formations and cliffs, which correspond to a close-up view, drew the attention of tourists, and the Rosa rugosa Thunb. blooming in the Hajodae area was enough to show a bizarre charm. This shows the various charms of Hajodae, suggesting that the management of such landscape is necessary. Fourth, a Chinese poem about Hajodae shows the spatial meaning of Hajodae. Looking into all sides of the Chinese poem about Hajodae, a case of unburdening one's mind on the landscape, and the aspect a person compared oneself to the natural landscape or projected one's consciousness onto it, and a case of recalling Ha Ryun and Jo Jun, illustrious retainers in the early Joseon Dynasty are confirmed. It can be seen that it results in the aspect of expressing one's impressions and looking back on history through the landscape.

  • We simulated a forest fire which was occurred in Yangyang area on 2005 and compared a results between two different weather conditions(real weather condition and mean weather condition since 1968) using FARSITE, which is a forest fire spread simulator for preventing and predicting fire in USDA. And, we researched a problem in the transition for introducing, so we serve the basic method for prevention and attacking fire. In the result, severe weather condition on 2005 effected a forest fire behavior. The rate of spread under real weather condition was about 4 times faster than mean weather condition. Damaged area was about 10 time than mean weather condition. Therefore, Climate change will make a more sever fire season. As we will encounter to need for accurate prediction in near future, it will be necessary to predict a forest fire linked with future wether and fuel condition.
