  • Up to date, the majority research on the major landscape elements in organic farming has been mainly focused on the practice of seeking efficiency. The problem is that this type of study contributes to polluting the agricultural environment and damaging the ecological circulation system. As an alternative, there is a growing body of research on organic farming, but it is not widely applied that research on how to manage the landscape considering the scenic characteristics of farming villages practicing organic farming. Hence, in this paper we utilized landscape adjectives as a way to enhance the objectivity of the organic agricultural complex landscape assessment. More specifically, not only this study used a landscape image of an organic agricultural complex to identify a landscape adjective suitable for the landscape elements but also this study confirmed the suitability of landscape adjectives comparing to the opinions of experts and the public. To carry out, this study performed the experts survey which is composed of 12 major landscape elements, including rice paddies and fields, monoculture and diverse crops, dirt roads, windbreak trees, accent planting, dum-bung(small pond), natural small river, natural waterways, plastic film houses, one-storied houses, and pavilion. As a result of deriving the landscape adjectives from the main landscape elements, there were nine landscape adjectives that were consistent with experts and the public, including "clear" and "Artless" for rice paddies and fields, while the mismatched landscape adjectives were 'traditional'. The accent planting was a combination of landscape adjectives such as 'natural' and 'clear', while the windbreak trees was a consensus of all landscape adjectives. Only two adjectives, 'friendly' and 'wild', agreed on the dirt load, nine dum-bung(small pond), ten natural small river, nine duckery, eight one-storied houses, 10 pavilion, eight monoculture and diverse crops, and three natural waterways. The most common landscape adjectives were windbreak trees, pavilions, and natural small river, all 10 landscape adjectives. However, it is considered that only three of the 10 landscape types on the dirt road and the natural number are matched. Thus, additional management measures will be needed. In addition, it was analyzed that the most common landscape adjectives were "Artless" and "friendly" 13 times. The landscape adjectives of the organic farming complex responded by experts were analyzed to be suitable for natural, clear, zingy, silent, traditional, artless, friendly, wild and Leisurely, and consistent with the general public's opinion.

  • Kaloula borealis is the species of Amphibia which belongs to Kaloula genus and it is the only species inhabiting in Korea. The population size and habitat of Kaloula borealis have been significantly decreased on a national scale due to the diversified developments and the uses of agricultural pesticides. Accordingly, the Ministry of Environment has designated and managed them as the class II of endangered species, in accordance with "Endangered Species Protection and Management Act"; however, a particular study focused on the ecological restoration of Kaloula borealis is desperately needed to prevent their extinction. This study was conducted to propose the HSI (Habit Suitability Index) of Kaloula borealis based on literature survey on ecology and habitats of Kaloula borealis, as well as their HSI. Factors to be investigated in HSI include: space, feed, cover, water(breeding) and threatening factors and the variables of each factor were also proposed. The distance from wetland, grassland, farm, stream and rice paddy, as well as the altitude of spawning pond were proposed as the variables of space, whereas the bed structure of forest and low-rise grassland were proposed as the variables of feeding. The variables of water (breeding) include the area of permanent and temporary wetlands, coverage of emerged pants (ratio of open water), water depth, water temperature, water quality, pH level, etc., whereas the presence of predator, distance from street and pollutants were proposed as the variables of threatening factor. The sub-standards by HSI factor of Kaloula borealis have been drawn from in-depth consultation with experts and based on this, the final HSI of Kaloula borealis was developed.

  • 본 연구는 근대경관이 병존하는 창경궁을 대상으로 조경 복원정비 양상의 타당성을 해석하였다. 연구의 결과는 다음과 같다. 첫째, 전담관리 조직에 따른 조경 복원정비 태도 변화를 이해하였다. 1908년 어원사무국의 황실재산 국유화와 환경미화, 1961년 문화재관리국 출범과 1963년 사적 지정에 따른 문화재 보존, 1983년 창경궁사무소의 복원 후속처리로서 환경정화, 1999년 문화재청 승격과 2019년 궁능유적본부 발족 이후 전문적 조경관리와 관람환경 제공이 포함된다. 둘째, 해방 이후 '창경원 환경정화기(1954~1977)'에는 유원지 시설의 기능 복구, 벚꽃놀이를 위한 시설 설치, 국립동물원 도약을 위한 환경정화가 이루어졌다. '창경궁 중건기(1983~1986)'에는 도시공원 기능을 포함한 복원정비 공사, 완충기능의 유보녹지 설정, 외부공간의 전통적 재조성, 산림지역 통합 정비가 진행되었다. '전통조경공간 보완기(1987~2009)'는 소나무로 획일화된 녹지 경관조성, 화계 중심의 다양한 식생 경관이 도입되었고, '관람환경 개선·정비기(2010~2022)'는 활용을 전제로 한 기본계획 수립되었으나 단위 공간에 집중된 소극적 정비가 고수되고 있다. 셋째, 조경 복원정비의 타당성과 관련하여 문화재 보존원칙의 '고유성' 측면에서 권역별 궁제의 회복이 전각이 밀집한 구역에서 40여 년간 확장되지 않음을 파악하였다. 또한, 다층위의 역사를 존중하는 여부로서 '시대성'은 두 차례 창경궁의 복원기준연대를 설정하는 과정에서 고려되지 않았다. 조선과 근대의 원상이 병존하는 후원 권역의 대온실 일원은 자수화단, 춘당지가 하나의 영역으로서 '완전성'을 만족시키지 못하였다. 문화재 공간의 활용 실태로 파악한 '효용성'은 내·외전 권역과 다른 프로그램들로 집중된 대온실과 춘당지의 장소성 확립을 시사한다.

  • 부영양호의 수질정화를 위하여 알루미늄 응집제를 호수에 첨가하고 조류와 부유물의 침강제거효과, 및 인의 감소효과를 측정하였다. 서울 석촌호와 강원대학교 구내 연못을 대상으로 8회에 걸쳐 첨가량을 달리하여 실시하였다. 7회의 처리에서는 황산알루미늄을 사용하였고 1회는 PAC를 사용하였다. 부유물질의 침강제거효과는 첨가량에 따라 좌우되었다. 10.0 mgAl/l를 첨가한 경우에는 부유물질, 조류, 인 등이 완전히 제거되었으나, 3.3 mgAl/l와 1.8 mgAl/l를 첨가한 경우에는 부분적인제거 효과가 있었다. 그러나 0.45 mgAl/l로 첨가한 경우에는 거의 개선효과가 보이지 않았다. 알루미늄 첨가가 부유물을 침전제거에 효과를 나타내기 위해서는 최소역치 (약 5 mgAl/l) 이상을 투여하여야 하는 것으로 결론지을 수 있다. 효과 지속시간은 외부로부터의 추가부하량 유입에 의해 좌우되는 것으로 보인다. 석촌호에서는 인근 하천수의 펌핑에 의해 곧 다시 혼탁해 졌으며, 구내연못에서는 강우후 주변의 토사가 유입되거나 지하수 펌핑으로 영양염류가 유입되면 곧 다시 조류가 번성하고 혼탁해 졌다. 응집제 투여의 결과로 pH가 지나치게 낮아지는 피해나 어패류에 대한 유해성 징후는 발견되지 않았다. 외부 오염원을 제거할 수 없는 호수에서는 응집제의 투여가 호수수질 개선의 임시적 대안으로 활용될 수 있을 것으로 보인다.

  • 청평사는 고려 초 창건되었지만 현재와 같은 공간의 틀은 고려 중기 진락공 이자현(1061-1125)이 1089년 입산해 선사상을 바탕으로 구축한 것이다. 이 연구는 이자현이 청평사의 기반을 구축한 문수원 이후 형성, 발달했던 선원 내 인공유적의 출현과 존속의 시대사적인 변천과정을 고문헌을 근거로 하여 개념적으로 구현해 보고자 하였다. 이자현의 문수원 때 조성된 경외 8암자 중 식암, 견성암, 양신암 등 세 암자만이 조선 후기까지 복원, 수리를 거쳐 건재하며 상징적 암자로 보존되어 왔다. 또 이자현 때 조성된 영지도 고려시대 연못의 원형적 의미를 지닌 소중한 조경유적으로 현재까지 남아있다. 이자현이 식재했다는 구송은 후계수를 이어가며 1800년대 중반까지 살아있었다. 조선 중기 보우대사(1509-1565)는 이자현이 구축한 문수원을 기반으로 청평사로 개칭하고 중창하면서 경내를 능인전(대웅전)만 제외하고는 모두 새로 짓고 확장하여 현재와 같은 경내 공간구조로 만들었다. 또 경외 영지의 개축, 궁원으로부터의 조경식물 이식 등 경관의 질을 한층 높여 청평사를 역대 가장 번성한 모습의 선원으로 만들어 놓았다. 그러나 조선 후기인 1800년대 중반 이후 청평사는 더 번성하지 못하고 쇠락의 길로 접어들면서 선원의 건축물은 경내 일부를 제외하고 모두 소멸되고 기타 시설물들은 방치된 채로 현대까지 남아 있었다.

  • This study seeks to present creation techniques increasing biodiversity while excluding techniques that avoid rooftop as a place for revegetation or techniques that are standardized and ecologically undesirable. To this end, a theoretical study was conducted including the identification of issues that need to be considered in introducing biotope creation techniques at a rooftop space using eco-pond or eco-park creation techniques. Based on the result, a creation process and techniques were presented for the rooftop of Kyungdong Energy Company building located in Bundang, Sungnam city. The conclusions reached in this study are as follows. First, when structural problems such as load or leakage are resolved and when it is planned as a habitat within a range of carrying load, a rooftop may be habitats for various organisms. Second, same creation techniques for eco-ponds or eco-parks may be applied to create biotope in a rooftop. In fact, the introduction of a wetland ecosystem on a rooftop may contribute significantly in increasing biodiversity. In addition, it would be desirable to approach traditional rooftop revegetation methods in an ecological aspect and to introduce indigenous plants and to offer habitats to insects and birds. Third, in order to create rooftop biotope, there should be enough studies and experiments on resolving structural problems and on techniques or technologies to create habitats. Since the Kyongdong Energy Company rooftop biotope described in this study is the first experimental site in Korea, it requires a series of process to identify problems and to improve them by monitoring the site in the future. Through such studies and experiments, efficient rooftop biotope creation techniques should be developed and disseminated.

  • $NO^3$-N removal was examined from July 2002 to December 2002 of a surface-flow constructed treatment wetland cell, which was a part of a treatment wetland system composed of four wetland cells and one distribution pond. The system was established on rice paddy near the Kohung Estuarine Lake located at the southern part of the Korean Peninsula. The lake and the paddy were formed by a salt marsh reclamation project. Effluent from a secondary-level treatment plant was funneled into the system. The investigated cell was created in June 2002. Its dimensions were 87 m in length and 14 m in width. It had an open water zone at its center, which was equivalent to 10 percent of its total area. Reeds(Phragmites australis) were transplanted from natural wetlands into the cell and their stems were cut at about 40 cm height from their bottom ends. Average 25 $m^3$/day of effluent from the plant was funneled into the cell by gravity flow and average 24.2$m^3$/day of its treated effluent was discharged into the Sinyang Stream flowing into the lake. Its water depth was maintained about 0.2 m and its hydraulic detention time averaged 5.2 days. The average height of the reed stems was 45.2 cm in July 2002 and 80.5 cm in September 2002. The number of stems averaged 40.3 stems/$m^2$ in July 2002 and 74.5 stems/$m^2$ in September 2002. The reeds were established initially well. $NO_3$-N loading rate of influent and effluent averaged 173.7 and $93.5mg/m2{\cdot}day$, respectively. Removal of $NO_3$-N averaged $80.2mg/m2{\cdot}day$ and its removal rate by mass was about 50 %. Considering the initial operation of the cell and the inclusion of the cold months of November and December in the analysis period, the $NO_3$-N removal rate was good.

  • This paper has aimed to determine how the Suwon Palkyong(水原八景: eight scenic wonders) were formed and the implicature of landscape, such as implicit intention and symbolic significance. For this, the significance and symbolic meaning of the Suwon Palkyong from the time of the 'Hwaseong Chunchu Palgyeong(華城春 秋入景)' have been investigated in order to determine the political and social arguments in Suwon Palkyong that surrounded the formation process and meaning. The 'Hwaseong Chunchu Palkyong' contains a variety of significant elements and factors of Pungmul(Korean drum & dance) as well as formative elements such as a castle. Plantings for beautiful scenery and water use for flood control have also been major elements in the development of Hwaseong. Therefore, it seems that the 'Hwaseong Chunchu Palkyong' is a catchphrase for the future image of the urban landscape. Most Suwon Palkyong sites such as Paldalsan, Namje, Yungneung, Manseokgeo, Chukmanje, Hwahongmun, and Yongji(a pond in Banghwa Suryujeong) are related to the 'Hwaseong Chunchu Palkyong'. 'Gwanggyo Jeokseol(光敎積雪: the landmark mountain, Mt. Gwanggyo with snow)' and 'Paldal Cheongnam(八達晴嵐: Mt. Paldal with shimmering air)' have also been added to Suwon Palkyong. Suwon Palkyong is either directly or indirectly related with water including the origin of Suwoncheon(水原川), an artificial reservoir for flood control and irrigation and Bibopungsu in Yungneung(隆陵), as well as the source of water for rituals after the death of King Jeongjo(正祖大王). Based on Suwon Palkyong, therefore, it can be said that water is a decisive medium in connecting old Suwon with Hwaseong New Town and essential element in the natural landscape. In conclusion, while Hwaseong is a 'Designed Landscape' that was created with a specific intention during the reign of King Jeongjo, the 'Hwaseong Chunchu Palkyong is a 'Desired Landscape' that envisioned a future landscape while Suwon Palkyong is an 'Evolved Landscape' related to the business affairs of the citizens. To completely restore Hwaseong, whose value and importance have been recognized internationally, therefore, the fundamental restoration of a cultural landscape as well as the restoration of the original form of the Hwaseong landscape including Suwon Palkyong is essential.

  • This study was conducted to understand the environmental and ecological function of habitat through evaluation of water environment, soil environment, vegetation characteristics, macro-invertebrate characteristics, and visual habits environment evaluation (SVAP) in Hongdong stream located in Hongseong-Gun, Chungnam Province, and hereafter to utilize the results for the habits reconstruction and improvement project. As the results of water quality analysis, BOD, COD, T-P was almost below the standard quality from upper stream to down stream. The construction of small reservoir, wetland and water purification facility, and the management of non-point pollution are proposed to improve these problems. The soil texture was sandy soil, which is unfitted with vegetation development. The construction of shallows and bogs, and induction of soil sedimentation and biotope formation are proposed to improve these problems. In the plant flora, total 90 kinds were observed with 81 species and nine varieties in total 36 families and 85 genera, and the naturalization rate was higher at down area than upper area. As the results of macro-invertebrate fauna survey, total 26 species and 297 individuals in 20 families and 22 genera were collected. Peltodytes sinensis, Chironomidae sp., and Culicidae sp., which are observed at polluted environment, were collected as dominant species. An appropriate vegetation management party idea is necessary, and it is done an idea in consideration of the soil and a physical characteristic. Visual habits environment evaluation (SVAP) result was mostly determined with below normal (Fair) grade. Pollution source interception, purification pond establishment, and various bog establishment are proposed to improve these problems. With the above results, the ecological environment was determined with bad condition, and the improvement of biotope was urgently needed through sustainable monitoring and management of streams habitat in rural area.

  • <하환정도>의 제작 시점인 1860년경을 기점으로, 그림에 표현된 무기연당과 일곽의 정원시설 그리고 경관 등을 현재와 비교하여 고찰한 연구의 결론은 다음과 같다. <하환정도>에는 내원(內園)인 국담(菊潭)을 중심으로 하환정(何換亭)과 풍욕루(風浴樓)가 핵심을 이루고 있으며, 1971년 이후 기양서원의 후신(後身)인 충효사(忠孝祠)와 영정각(影幀閣) 등이 보태졌다. 하환정 반대편 국담 지안(池岸)에는 3기의 괴석과 함께 다채로운 초화류와 화관목이 식재되었으며, 중도(中島)에는 봉황석(鳳凰石)과 납두석(衲頭石)의 배치와 함께 2종의 수목이 그려져 있는데 이 중 하나는 단풍나무로 확인된다. 그림의 외경(外境)에는 무기연당을 중심으로 상부로는 작대산과 천주산이, 하부로는 정충비각과 현재는 멸실된 비보숲이 묘사되어 있다. 주목할 만한 성과로 외경의 작대산 아래 십 여기의 봉분 형태의 주씨묘군(朱氏墓群)과 함께 묘사된 '별업 유회정(別業 有懷亭)' 유구(遺構)를 주씨 선산인 산정리 일대에서 확인하였다. 확인된 유구는 방형의 지당(池塘)과 석가산인 중도(中島) 그리고 석비 망추대(望楸臺) 등이며 지당내 석가산은 자연석에 약간의 가공을 한 뒤, 여러 개의 괴석을 첩석한 형태로 측면에는 '경암(敬嵒)'과 '세심(洗心)'이라 각자(刻字)되어 있다. 특히 '경(敬)'자(字)는 소수서원 경자바위(敬字岩)의 그것을 모사(模寫)한 것으로 풍욕루 현판은 물론 주세붕을 모신 관내 무산사(武山祠)에서도 발견되는 주씨 정원의 상징적 정원언어가 되고 있다. <하환정도> 외경에서 유회정과 석가산을 갖는 방당(方塘)의 이름은 '태화지(泰和池)' 또는 '정우당(淨友塘)'이라 하였으며 석가산의 이름은 '소금강(小金剛)' 또는 '소방장(小方丈)'으로 명명되었음이 확인된다. 이는 국담의 석가산인 '봉래산'에 비견되는 명칭으로, 양 공간에 관련성을 이해하는데 중요한 연결고리가 되고 있다. <하환정도>는 함안 칠원리에 입향한 15대손 주씨문중에서 주도하여 그린 일종의 장원도(莊園圖)로서, 내원은 물론 외경의 상황을 세밀하게 묘사하고 있어 무기연당원 및 주변 경관을 이해할 뿐 아니라 무기연당을 포함한 외경의 정비 및 복원의 중요한 단서를 제공하고 있다고 판단된다.
