최근 몇 년동안 지속가능하고 효과적인 수자원 관리는 전체적인 접근방법이 요구되고 있으며, 사회와 경제발전과 생태계 보호 및 토지이용과 수자원 이용의 적절한 관리와 연결된 개념이 필요하다. 이러한 관점에서 유역을 간단한 고정된 지역적인 문제라고 생각하는 것보다 전체로서의 유역 기능을 개선하는데 노력이 필요하다. 또한 사회와 경제발전으로 인해 도시화, 여가 관광지역 및 사회기반시설의 확장 그리고 자연환경의 변화가 발행하고 있다. 효과적인 토지이용 배분과 자연지역의 보호도 중요하지만 잠재적인 홍수피해 저감도 중요한 문제이다. 토지이용의 변화는 많은 이해관계자들로부터 유발되는 문제이기 때문에 거시적인 관점에서 고려되어야 한다. 본 논문은 다양한 관계자와 자연환경과의 연결과 상호작용 유형을 이해하고 다양한 정책선택과 자연환경 상태가 토지이용 변화에 미치는 영향을 이해하고자 한다. 인간의 활동으로 인해 발생하는 토지이용의 변화를 모의하기 위해서 행위자기반모형(Agent based Model, ABM)으로 접근하고자 한다. ABM은 유역관리의 이해당사자간의 정책과정을 도출하고 다양한 유역관리 대안을 평가하기 위해서 홍수위험, 자연개발 및 비용과 같은 유역관리의 영향을 설명하는 통합된 유역모델이다. 여기서 토지이용은 경제적, 지형학적 상황, 공간계획 및 홍수방어정책에 좌우되며, 토지의 속성과 규칙을 통해 토지이용이 선택되게 된다. 본 모형을 통해 공간적으로 분포된 행위자의 운영을 기반으로 종합적인 토지이용 패턴을 분석하였다, 이를 통해 토지이용 결정에 영향을 주는 인자를 추정하여 통합홍수관리 목적에 맞는 관리 대책의 결정 및 설계를 가능토록 하였다.

This paper evaluate use on facilities of green tourism by participator's questionnaire and urban inhabitants' questionnaire. As the result of study, it shows follows; 1) To make town look more traditionally we should rebuild the buildings and the styles of roof with our own traditional rural system. And, we also change the block and brick style fence into soil or rock one instead to look rural path. The agricultural land and watercourse should be left naturally to be looked non-polluted environment. 2) The outdoor toilet, washing stand and distribute should be maintained and managed clearly every time. Residents' own housing also should be maintained to promote the home-stay lodging. 3) To improve the satisfaction of people's need of agricultural product, the special market building or place that could be packed and sold the product at the same time should be built or made. And, it should be located in the harmonious spot with the natural scenery and good parking lot.

This study established the definition of invasive disturbance species for a sustainable management and biodiversity, and derived the influence factors caused by the species. To define the species, the paper reviewed similar words such as alien species and invasive species, using standard definitions. Also reviewed the results of recent research on the factors of the species. The paper defined the invasive disturbance species as an species whose establishment and spread threaten ecosystems, habitats or species with economic or environmental harm including native and non-native. Through the reviews, The factors were classified as geographic (altitude, slope, and soil, etc.), climate (temperature, precipitation, climate change, etc.) and, anthropogenic (land use, population, road, and human activity, etc.), and species & vegetation structure (species property, local-species richness, and canopy, etc.). Especially, human activity such as urbanization and highways may be associated with both higher disturbance and higher propagule pressure. In the further study, it is required development of mitigation strategies and vegetation structure model against invasive disturbance species in urban forest based on this study.

Many countries over the world have taken many discussions and endeavors on environmental improvements of energy savings and greenhouse gas emission reductions for solving global climate change problems. In Korea, pre-considerations of environment-conscious factors in buildings have been taken to be critical with new constructions and renovation markets. In this situation, the Korean Green Building Certification(KGBC) system to induce the diffusion of sustainable buildings was introduced in 2002 and developed as an improved version of the G-SEED(Green Standard for Energy and Environmental Design) system in 2013 after major revisions. This research examines the importance of assessment criteria on apartment buildings to certify green buildings using the AHP(Analytic Hierarchy Process) method and suggests a new direction on certification assessment standards from the AHP result. In order to apply the AHP method, the survey via e-mail was conducted to design staffs in domestic architectural firms. As a result, assessment criteria such as ecological environment, indoor environment, and energy & environment pollution among 7 main ones proved to be important on assessing the G-SEED system for apartment buildings, while criteria such as land use & transportation, material & resource, water circulation management, maintenance management did relatively unimportant.

This work aims to establish the landscape ecological countermeasures to improve the sustainability of urban mountain forest and to enrich the biodiversity in twenty mountains of the Seoul Metropolitan City. Landscape ecological analysis was conducted based upon various criteria, such as area and elevation of mountains, flora, naturalized plants, vegetation, forest types, mountain trails, and public facilities. Various measures were suggested for the better maintenances of floristic diversity, introduced plants, vegetation and forest types of urban mountain forests. Sustainable recommendations for land use adminstration were developed for the preparations of a climate change-adapted urban mountain forests, as well as rational managements of ecosystem, walking trails, and public facilities within mountain forest. Rich and diverse natural vegetation as well as high floristic diversity were reported at mountains with higher elevations, larger area size, and rich landscape diversity. Mountains with low elevation, small size with easy public access, however, might require an urgent action to decrease the burdens by anthropogenic disturbances and urban development.

Recently some urban areas have been flooded due to heavy storm rainfalls. Though major causes of these floodings may be attributed to localized heavy rainfalls, other factors are related to urban flooding including deficiency of storm sewer network capacity, change of surface runoff due to covered open channels, and operational problems of storm drainage pump stations. In this study, hydrologic and hydraulic analysis of Sutak basin in Guri city were carried out to evaluate flooding problems occurred during the heavy storm in July, 2001. ArcView, a world most widely used GIS tool, was used to extract required data for the hydrologic analysis including basin characteristics data, concentration times, channel routing data, land use data, soil distribution data and SCS runoff curve number generation from digital maps. HEC-HMS, a GIS-based runoff simulation model, was successfully used to simulate the flood inflow hydrograph to Sutak pumping station.

This study examined the regulation status on wastewater treatment in agro-food processing and a case study on effluent treatment m ethods was carried out to evaluate any change after the mitigation of regulation. First, in order to clarify the area of investigation, the definition of small-scale agro-processing facilities was reviewed through literature survey and local government ordinance. The current law were separately analyzed into four areas; effluent treatment facilities, development of agro-processing industries, land use and food processes equipment. The exclusion clauses on wastewater discharging facility in the enforcement regulation were defined in detail, which can be served in practice. Site survey, after the questionnaire survey of the person in charge of the local unit, was carried out. As the result, this survey confirmed the positive effects of the deregulation on promoting sewer system service in rural areas, introducing the new processing construction and so on. In addition, it was found that some matters to be considered to determine whether to introduce wastewater treatment plan for public food processing facilities.

The purpose of this study is to present the conditions and methods for keeping the sustainability of the landscape resources of the East Coast of Gangwon province, the republic of Korea by investigating the landscape resources management in the area and pointing out its problems. The problems of the landscape resources management are： 1) the disturbance of the persistence of life by reclamation, the population reduction in the ecosystem due to the overload in environmental capacity, and the severance of space between land and water. 2) the reduction of the benefits from indirect experience by interfering with the conservation of fluxes -- the manipulation of horizontal arrangement of the landscape resource, the visual disturbance by the construction of high-storied buildings, and the disharmony between the color/image and the environment. The means for keeping sustainability of the landscape resources include the regulations of development and use, the change in the recognition of the value of landscape resources and the moral system, and the improvement of resource management skills.

토지이용의 변화는 강우에 의한 유역의 수문 및 수질에 많은 영향을 미친다고 알려져 있다. 최근에 도시유역 뿐만 아니라 농촌유역에서도 도시화 및 시설재배지의 증가 등으로 인하여 토지이 용의 변화가 급격히 일어나고 있으며, 이는 곧 유역의 물 순환에 다양한 영향을 미칠 것으로 판단된다. 본 연구에서는 AGNPS 모형을 이용하여 토지이용 특성의 변화가 농촌유역 수문 및 수질 환경에 미치는 영향을 평가하였다. 시험유역은 서울대학교 지역시스템공학과에서 운영하고 있는 발안 유역의 HP#6 소유역으로 다양한 토지이용상태를 보이고 있다. 본 연구에서는 선정된 시험유역에 대해 수문 수질 자료와 기타 수집된 자료를 이용하여 유출량, 유사량, 그리고 영양물질에 대해 보정과 검정을 실시하였다. 시험유역의 비점오염 배출특성을 고려하여 토지이용의 변화 시나리오를 구성하여 분석하였다. 선정된 시나리오는 유역 상류에 위치한 나지의 피복상태를 초지로 개선하는 경우(시나리오 I), 현재의 논이 비닐하우스 등 시설재배지로 변경되어 불투수면이 증가하는 경우(시나리오 II), 시나리오 I과 시나리오 II가 복합적으로 일어나는 경우(시나리오 III) 등으로 구성하였다. 각각의 시나리오를 통하여 유역 내 토지이용의 변화에 따른 수문 및 수질영향을 정량적으로 예측 및 평가하였다. 본 연구를 통해 농촌유역 미래의 토지이용 변화가 물 순환에 미치는 영향을 분석함으로서 지속가능한 농촌유역의 개발 계획 수립 및 물환경 정책 결정 등에 활용이 가능할 것으로 기대된다.
