This study aims to offer effective policies for managing local temperatures and reducing the heat island effect by identifying elements that affect local temperatures. The three elements of natural environment, land use, and land coverage were first selected, and then control factors were applied, including season, weather, and measurement units for wind speed. In order to analyze these factors' relations to summer temperatures, an integrated model was developed, and an analysis was conducted of the urban heat island reduction effect of elements impacting local temperatures. The analysis used nationwide weather system (AWS) data from July and August 2007 and 2011-2016, land coverage data provided by the Ministry of Environment, and land use area data from local governments after rearranging them based upon their falling within a 500-meter radius ($0.79km^2$) of AWS measuring points. The study results show that the natural environment, land use, and land coverage all have a relation to changes in local temperatures. Natural elements have the greatest impact, and land use has the lowest. The results could provide basic data for establishing more effective policies to mitigate the heat island effect and strategies for enhancing the sustainability of cities.

This study proposes the big data policy and case studies in Korea and the application of land and housing of spatial big data to excavate the future business and to propose the spatial big data based application for the government policy in advance. As a result, at first, the policy and cases of big data in Korea were evaluated. Centered on the Government 3.0 Committee, the information from each department of government is being established with the big-data-based system, and the Ministry of Land, Infrastructure, and Transport is establishing the spatial big data system from 2013 to support application of big data through the platform of national spatial information and job creation. Second, based on the information system established and administrated by LH, the status of national territory information and the application of land and housing were evaluated. First of all, the information system is categorized mainly into the support of public ministration, statistical view, real estate information, on-line petition, and national policy support, and as a basic direction of major application, the national territory information (DB), demand of application (scope of work), and profit creation (business model) were regarded. After the settings of such basic direction, as a result of evaluating an approach in terms of work scope and work procedure, the four application fields were extracted: selection of candidate land for regional development business, administration and operation of rental house, settings of priority for land preservation, and settings of priority for urban generation. Third, to implement the application system of spatial big data in the four fields extracted, the required data and application and analytic procedures for each application field were proposed, and to implement the application solution of spatial big data, the improvement and future direction of evaluation required from LH were proposed.

This article aims to conserve greenbelts by adopting the national trust approach. This article reviews the current issues and problems in managing greenbelts in Korea. And this article redefines the function of greenbelts, and then suggests the new principles of management strategies of greenbelts. Greenbelts is to provide green open space for urban residents and to contain urban sprawl not to reserve lands for the future urban development. This article proposes basic principles for the effective management of green belts. They include (1) preserving environmental value, (2) maximizing public access to open space and environment resources, and (3) enhancing public-participation and collaboration among different groups and organizations for the management of greenbelts. These principles are closely related to those of national trust movement. This article suggests the government to adopt national trust approach (organization, funding, site selection criteria, legislation) to improve the environmental-friendly conservation and management of greenbelts in Korea.

A preliminary study was conducted to introduce the concept of asset management in developing maintenance strategies for public facilities. A survey was carried out to analyze public institutions' maintenance status, thereby leading to an asset management system. The survey identified the maintenance priorities for the asset management system, evaluated the weight factor in selecting facilities, and analyzed the current maintenance system. The purpose of the study is to assess the system transitioning to asset management systems considering the life cycle of the facilities from safety management-oriented maintenance policies. As a consequence of the survey results, the study presents data for establishing an asset management system.

The purpose of this study is to make practical application of the results as basic data of National Park management-policy by surveying and analyzing management goals, management missions, land zoning, numeral of visitors, management organization, management staff and revenue and Expenditure budget of 1992 and 2004 those are main factors to know the management system well. The main management missions was found not only to put value on developing nature program but also to prepare for keeping and renewing of nature resources. The change of zoning land was researched to be controlled and nature preservation area was showed to be enlarged. While management missions and visitors have been increased, there weren't raise of organization and staffs at all. And expenditure budget had management formation by manpower. Although there are progressive changes in park management system during the period, several improvements are needed in details. They are as follows; To be sustainable preservation and usage which are the intrinsic roles of National Park by increasing the government investment than own revenue.

This study empirically investigates whether urbanization triggers urban disaster damages in the metropolitan areas of Korea by applying panel data analysis. Issues are approached with respect to the perspective that increased natural disaster damages are closely related with urbanization. This paper describes the conceptual framework of disaster management to understand the factors that determine urban disaster damages in Korea. This study used a simplified model with some key factors for analysis, because flood damage factors in urban areas are too diverse, and a full understanding of every cause is not feasible. The results indicate that urbanization does not necessarily lead to increasing urban disaster damages and if properly managed, urbanization can actually reduce urban disaster damage.

In the debates of development gains, the general rule is that it results from actions other than those of the landowner, most notably of the public sector as in granting of permissions for the development of specific land uses and densities or through infrastructure investments, or of socio-economic forces due to a general capital accumulation in space. A huge academic literature has investigated the development gains capture that refers to the process by which a portion of or all land value increments attributed to the community effort are recouped by the public sector. Policy instruments for applying development gains capture are based on deepening land value taxation, financing infrastructure, controling land use. But one of the most basic for the efficient policy implementation is the accurate estimation of development gains. This paper estimates the development gains generated by the total 204 building land projects of Korea Land Corporation and Korea National Housing Corporation since 1995.

인간활동으로 인해 서식처의 변화, 서식처의 파편화를 비롯하여 기후변화, 토지이용의 변화 등으로 생태계 생물 다양성은 빠르게 손실되고있는 상황이다. 특히 생물 다양성은 생태계 복원력에 중요한 인자로서 유역의 건전성 회복을 위해 생물 다양성을 중요한 인자로 고려하려는 경향이 커지고 있다. 유역 건전성은 주로 큰 하천에서의 친수성, 서식처, 유량 및 수질 등에 적용되어왔고 국내에서는 최근 들어 유역 건전성을 확보하기 위해 수량 및 수질관리, 환경문제 등의 해결을 위해 유역관리 차원에서 접근하려는 시도가 시작되었으나 어떠한 수단을 통해 생물다양성과 서식처 관리를 접근할 수 있는지에 대한 연구는 아직 부족한 실정이다. 이에 본 연구에서는 최근 20년 동안 도시화, 댐 건설 등 토지이용변화가 크게 발생한 금강유역(9,865 km²)을 대상으로 InVest 모델 중 서식처 가치평가 모델 (Habitat Quality Model)을 이용하여 유역의 서식처 가치를 평가하고 이를 수생태계 건강성 모니터링 자료와 비교하여 모형의 적용성을 평가하고자 한다.

우리나라는 농산물시장개방이후 휴경면적의 증가, 농지전용, 도시화의 가속화, 시설작물 재배면적 변화 영향에 의한 논과 밭의 이용 패턴변화 등으로 농촌지역의 토지이용구조가 변화되어 왔다. 이는 곧 국내 토지이용패턴의 변화로 연결되고, 농업구조의 변화는 농촌경관, 농업용수 이용, 농촌지역 비점오염 물질 발생패턴의 변화를 야기할 것으로 예상되고 있다. 본 연구에서는 금강권역을 연구지역으로 하여, 농업지역의 토지이용변화 중 논 내 시설작물 재배면적 변화에 주안점을 두고 토지이용변화 예측모형인 CLUE-s(Conversion of Land Use and its Effects at Small regional extent) 모형을 이용하여 미래 농업지역의 토지이용변화를 예측하고자 하였다. CLUE-s 모형의 입력 자료로 국가수자원관리종합시스템(WAMIS)의 1980~2010년까지 5년 간격 토지이용 통계자료 및 환경부 2008, 2013년 중분류 토지이용 자료에서 금강유역을 추출하여 구축하였다. 모형의 입력자료를 위해 토지이용 항목을 총 7개(수역, 시가지, 논, 밭, 시설재배지, 산림, 초지)로 분류하고 특별토지이용 정책 자료로 농업진흥구역도 및 국토환경성 평가도를 이용하였다. 관측자료의 경향을 이용하여 환경부 중분류 토지이용 변화를 기준으로 농업지역(논, 밭, 시설재배) 변화에 대한 회귀식을 도출하였다. 본 연구의 결과를 활용하여 농업지역 변화에 따른 수문 및 수질의 영향을 파악하고 미래 토지이용 변화에 따른 농촌지역 비점오염 물질 발생패턴 등을 분석하기 위한 기초 자료로 활용할 것으로 판단된다.
