Today, the space itself of rivers have become the specimen of environmental pollution due to the change of living pattern following the development and urbanization during the past some 30 years, and the stream ecosystem has been destroyed due to be changed to straight, dike or concrete stream, and the habitat of animals and plants have been damaged. The purpose of this study is to analyze of character and problem of environmental friendly improvement method which is promoted in Korea since 1990, and to present plan to restore the destroyed ecosystem of the stream continuously and the basic data which will be used in environmental friendly method.

This paper presents how Digital Knowledge Ecosystem such as "Govi Nena" (translates as agriculture intelligence) can be used to provide a more effective and practical solution to eliminate the inefficiencies in agricultural markets and achieve higher productivity and price stability. In order to establish the framework to analyze the system, this paper uses a set of hypothetical scenarios faced by value chain actors based on a review of the literature, established knowledge and recent developing country experiences. The scenario analysis reveals that "Govi Nena" enables farmers to make effective production decisions, deepens the level of value chain integration, and enhances the level of welfare for the society as a whole.

BACKGROUND: To quantify carbon exchange at agricultural ecosystems in South Korea, net ecosystem exchange (NEE) at three croplands including a rice paddy, a bean field and an apple orchard was measured on the basis of the eddy covariance technique. METHODS AND RESULTS: NEE of CO2 during the growing season (June to September) averaged over the recent two years (2018-2019) was the highest at rice (-4.49 g C m-2 day-1), followed by the bean (-3.12 g C m-2 day-1) and apple (-0.93 g C m-2 day-1). The diurnal variation of NEE was the highest at the rice, while the seasonal variation of it was the highest at the bean than others. In terms of yearly variation, the rice paddy and the bean field absorbed more CO2 in 2019 compared to 2018, while the apple orchard absorbed less. CONCLUSION: Our results confirmed that these croplands consistently acted as net sinks for CO2 during the growing season because an amount of CO2 uptake from photosynthesis was larger than one of its emissions from respiration. The quantification of net CO2 exchange at agricultural ecosystems may help to better understand the local carbon cycle over various time scales.

Remodeling of agricultural facilities can be defined as follows; it is received newly social needs which calamity is reduced, its function is improved, ecosystem is maintained, water-friendly space is preserved. By those remodeling, environment water and tour water with role as a place of rest and leisure sports, and so forth can be ensured. Therefore, on this study, we would propose the approach of the repair and enhancement of agricultural facilities which can reflect those social demands.

갈색여치 알의 휴면타파에 대한 온도의 영향을 조사하기 위하여 실내 및 야외의 다양한 온도조건에서 배자발달 및 부화율을 측정하였다. 갈색여치 휴면알을 $25^{\circ}C$에서 계속 사육할 경우 부화하지 않았으며 1회 저온처리($5^{\circ}C$ 또는 $10^{\circ}C$에서 30, 45, 60일간)한 후 $25^{\circ}C$에서 사육해도 부화하지 않았다. 또한, $5^{\circ}C$에서 같은 기간 동안 2회 저온처리를 한 경우에도 부화하지 않았다. 그러나 $10^{\circ}C$에서 2회 반복하여 저온처리를 했을 때에 3.6${\sim}$26.7%의 알이 부화하였다. 1회 저온처리 후 $25^{\circ}C$에서 부화하지 않은 알의 무게를 측정한 결과 $5^{\circ}C$에서 저온처리한 알들은 변하지 않았으나 $10^{\circ}C$의 경우에는 1.5배 증가했다. 90일 된 알을 2007년 9월에 산간지역 3곳의 땅속에 묻은 후에 월동후 부화율을 관찰한 결과, 충북 영동 회포리, 비탄리 및 경북 화산리에서 1회 월동알의 부화율은 11.3, 3.5, 4.1%였지만 2회 월동알은 25.1, 21.6, 0.4%였다. 부화는 3월 중순부터 4월 중순 사이이지만 남쪽에서 약간 일찍 부화하였다. 이 시기의 토양온도는 8${\sim}$$12^{\circ}C$로 나타났다. 본 연구결과 갈색여치 휴면알은 반복적인 저온기간의 영향이 크며 야외에서는 1회 또는 2회의 월동기간이 필요한 것으로 판단된다.

Ecosystem services play a role in promoting sustainable development by contributing to human welfare. For sustainable development, a balance between supply and demand for ecosystem services must be made. In this regard, in this study, factor analysis was performed using the results of measuring ecosystem services for the supply of ecosystem services and national statistical data representing socio-economic factors for demand for ecosystem services The results of analysis for Gyeong-gi Province are as follows. The service supply based on the result of ecosystem services was divided into the mixed service provisioning as factor1, the food provisioning as factor2, and the P retention service provisioning area as factor3. As for the demand for services based on socio-economic factors, factor1 is divided into urbanized areas, factor2 is forest development area, and factor3 is agricultural activity development area. Local governments that maintain balance were evaluated as Pocheon, Yangpyeong, Icheon, Pyeongtaek, Goyang, Suwon, Gwangmyeong, and Osan, and imbalanced local governments appeared in Gimpo, Uiwang, Anseong, and Yeoju. A management plan to maintain the balance between supply and demand of ecosystem services was suggested. The analysis method and results of this study are expected to be applicable to various local governments through regional expansion.

연못형습지(Pond Wetland)는 우리나라 농업경관에서 많이 분포하고 있다. 이러한 연못형습지는 생물다양성을 위한 중요한 자원으로 평가 받는다. 하지만 연못형습지(Pond Wetland)에 대한 연구는 유형분류에 그치고 있다. 따라서 본 연구는 연못형습지의 생태계서비스(Ecosystem Service) 기능을 알아보았다. 연구방법은 총 3단계로 기능분석, 기능도출, 중요도 분석의 순으로 진행하였다. 선행연구를 분석하여 총 22가지의 기능을 도출하였다. 전문가 설문 결과 22개 항목 중 생물, 환경, 사회문화 분야에 각 4 기능씩 총 12개 기능으로 선별하였다. 항목간 AHP(Analytic Hierarchy Process)를 실시하여 기능별 중요도를 산출하였다. 중복된 기능은 통합하여 연못형습지의 생태계서비스 기능 10가지(1. Water Storage & Irrigation, 2. Vegetation Diversity, 3. Amphibian & Reptile Habitat, 4. Water Purification, 5. Aquatic Insect Habitat, 6. Nutriments Control, 7. Groundwater Recharge, 8. Fishery Habitat, 9. Eco-Experience & Education, 10. Aesthetic landscape)를 도출하였다. 향후 기능별 중요도 분석과 경제적 가치 지표를 적용하여 연못형습지의 생태계서비스 평가에 활용 할 수 있을 것으로 판단된다.
