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.

This thesis attempted to generate ideal tea culture space that connects environment and culture. Therefore, this examines: First, history of tea and the characteristics of tea culture space from Gochosun to modern times was reviewed Second, psychological factors (spirit of tea) of Korea tea culture space were reviewed. Third, the connection between the concept of tea culture space and Human Ecosystem Model by was analyzed. Also, this thesis examined how the culture of ecosystem and why tea culture space is needed. because tea includes varieties of ingredients for protecting environmental pollution. Finally, tea culture spaces were reviewed each region during Chosun dynasty, and tea culture space of recent tea users. In order to study tea culture space, complex residential area and single residential areas were compared. The useful of tea culture space as a ecological space was also examined. To achieve the purpose of this study, related literatures were reviewed, and investigations of museums and a survey on modern living space were also conducted. The results show that the space of our tea culture were affected by nature worshipping of Gochosun, Buddhism of Koryo, and Confusianism of Chosun with 'Pungryu', the idea that enjoys nature, thereby applying environment-friendly ecological beauty to their living space and life. The cultyral space in Korea is composed of natural environment such as mountain, sea, rock, or trees and artificial environment such as pond or pavilion. In the future, oriental culture with metaphysical value will lead the world culture, and especially, tea culture would play an important role regardless of nationality, race, religion, and ideology. Therefore, establishing a tea culture space in a living space would be the fundamental methods that would be able to settle down such tea life into our daily life. Our attempts to create ecological tea culture space as a integrated cultural space of natural, artificial, and human behavioral environment will contribute to enhance our quality of life.

우리나라에서는 유역 특성별 비점오염물질 유출특성을 파악하고 최적관리방안을 도모하기 위해 2000년 이후 다양한 형태의 실험실 규모 또는 실증 규모 최적관리방안(Best Management Practices, BMP) 시설에 대해 연구가 진행되고 있으나 유역 특성상 자정작용의 기회가 주어지지 않는 연안지역에서의 비점오염물질 유출특성 및 관리방안에 대한 연구는 미비한 상태이다. 최근 연안지역 개발에 따른 불투수층 비율은 지속적으로 증가하고 있으나, 초기우수의 직접유출을 방지하기 위한 완충 시설 및 최적관리방안 시설은 전무한 상태이다. 본 논문에서는 충남 보령시 대천항 주차장을 중심으로 연안 지역의 비점오염물질 유출특성을 파악하고, 이를 저감하기 위한 최적관리방안을 설정하여 연안지역 비점오염원 관리에 대한 기초자료를 제공하였다. 연안지역은 지역특성상 해안과 접하고 있기 때문에 지하수위가 낮고 경사차가 크지 않은 평탄한 지형을 이루고 있다. 즉, 최적관리방안을 선정하는데 있어 유출입구의 수두확보문제와 굴착 깊이에 제한을 받으며, 인공습지 및 저류지와 같은 대규모 저류형 시설의 입지조건으로는 부적합하다. 또한, 연안지역은 강우유출 특성상 염분의 함량이 높기 때문에 식물 생장에 미치는 영향이 커 식생을 이용한 자연형 최적관리방안 시설을 적용하는데도 제약을 받는다. 연안지역 비점오염원 유출 특성과 연안지역 지리 지형적 조건을 고려하여 선정된 최적관리방안 시설의 주관평가 결과 시공시 굴착 깊이가 적고, 식생의 이용이 제한적인 침투수로 형태의 시설이 적합한 것으로 사료되며 유지관리 측면에서도 유리하다.

With an objective to provide basic information for the management and the prediction of eutrophication in lentic water Systems, total amount of Kjeldahl nitrogen(T-N) and phosphorous(T-P) from irrigated water and drained water from flooded paddies were investigated during the rice growing period of 1988. A 29.3 ha paddies near Jungnam-myun, HwaSung-gun, Gyungi Province, Korea was instrumented for measuring runoff and sampling irrigated water and drained water from paddies. The following conclusions may be drawn from the result of this study. 1.During 115 days of investigation, T-N load for paddies was 362.6kg and T-P 63.44kg.These would be converted to 12.4kg T-N/ha and 2.17kg T-P/ha, respectively. 2.The T-N and T-P loadings in different periods showed a significant difference. The 25% of T-N loading was drained soon after fertilization period and 60% was drained during the rainy season from July 5 to July 24. 3.Annual loadings from paddies could be calculated to 30kg T-N/ha/year and 52kg T-P/ha/year considering non-measurement periods. 4.After the rainy season, the nutrient loads from drained water showed much less than those from irrigated water, and it may be suggested that the paddies would act as a stabilization pond. 5.The average concentrations of nutrients at 0.9km downstream from investigated paddies were 2.02(T-N) mg/l and 0.52(T-P) mg/I, which were 1.82(T-N) mg/l and 0.056(T-P)mg/l lower than those of drained water from paddies.

The field scale experiment which is constructed with four sets (0.88 ha for each set) of wetland (0.8 ha) and pond (0.08 ha) systems was performed to examine the effect of plant coverage on the constructed wetland performance and to recommend the optimum development and management of macrophyte communities. After six growing seasons of wetlands, plant coverage was about 100%. And the concentration of DO showed low value (1.0~5.4 mg/L). This is caused by a blighted plant consumed dissolved oxygen with decay in water column. As the result, water column went to be anaerobic conditions and T-N removal rate are 58~67%. Dead vegetation increased nitrogen removal during winter because it is a source of organic carbon which is an essential parameter in denitrification. However, wetland released phosphorus caused by a blighted plant and accumulation, the removal rate of phosphorus might be decreased. To rise of DO concentration, the three open-waters were constructed in cell 3 and 4. Cell 3 has two open-waters (width 10 m, depth 1.8 m) and cell 4 has one open-water (width 20 m, depth 1.8 m). As the result, DO concentration and treatment efficiency of nutrient and BOD were improved. In case that constructed wetland is operated for a long time, physical circulation structure such as open water help continuous circulation of aerobic and anaerobic conditions. Through the constructed open-water, treatment efficiency of phosphorus and nitrogen in wetland could be improved effectively.

Low impact development (LID) technique is recently proposed as new concept to reduce surface runoff and pollutant loading with various best management practices (BMPs). In this study, LIDMOD2, which is one of the model to evaluate LID, was applied at Mohyeon developing area to evaluate the redcution of annual runoff and pollution loading, cost-reduction efficient by LID with design of structural BMPs including bioretention, wet pond, and wetland. As a simulation results, the bioretention had the highest reduction efficiency for runoff (41.43%), and 22% for T-N and 22% for BOD. Wet pont had the highest reduction efficiency for T-P as showing 25% of reduction rate. As a results of cost-reduction efficient, wet pont represented the highest cost-effective for T-N and BOD with showing 0.43 T-P kg/million won and 17.37 BOD kg/million won, respectively, and bioretention represented the highest cost-effective for T-P with showing 2.52 T-P kg/million won. LID technology could reduce effectively surface runoff and nonpoint source pollution and construct sustainable development. LIDMOD2 could be suggested as useful tool to evaluate and design LID.
