지속가능한 토지이용을 위한 경관규모 생태계평가기법 연구
황국웅 ( Kook Woong Hwang ),박소윤 ( So Yoon Park ) 한국지리정보학회 2003 한국지리정보학회지 Vol.6 No.1
본 연구에서는 경북 봉화군을 대상으로 하여 지속가능한 토지이용을 위한 생태계정보를 추출하기 위하여 경관생태학적 방법에 의한 생태계의 종합적 건강성을 평가하였다. Landsat TM 위성영상을 가지고 봉화군에 대한 토기피복분류를 실시한 후, 산림지역에 대하여 경관지수를 적용하여 생태계 건강성에 대한 면별 비교평가를 실시하였으며, 그 결과를 정규식생지수(NDVI)와 비교하였다. 경관지수를 이용한 생태계 건강성 종합평가에서는 석포면, 재산면, 소천면이 가장 양호한 것으로 평가되어 지역의 생물종의 풍부도와 다양성이 높을 것으로 보여진다. 봉화읍은 10개 면 중에서 생태계 건강성이 가장 낮은 상태로 나타났다. 정규식생지수(NDVI)와 비교하였을 때, 재산면, 춘양면, 소천면의 수치가 가장 높고, 봉화읍의 수치가 가장 낮은 것으로 나와 춘양면을 제외한 결과는 생태계 건강성 종합평가와 비슷한 결과를 보여주었다. 앞으로 보다 많은 보완적인 연구가 필요하지만, 경관지수를 이용한 경관규모 생태계 평가기법은 지속가능한 토이지용과 관련한 생태계 정보를 제공할 수 있을 것으로 기대된다. The purpose of this study is to evaluate the ecosystem soundness in landscape scale using landscape indices, and to extract regional information that can be used for sustainable landuse planning. About BongWha-gun, the landcover classification using Landsat TM images and patch analysis ware carried out, and some landscape indicies were calculated using geographic information system(GIS) and patch analyst program. As the results of this study, Seokpo, Jaesan and Sochun got higher scores in landscape indices related to the ecosystem soundness. But, Bonghwa-eup got lowest scores in the 10 regions. When compared with normalized difference vegetation index(NDVI), this result showed consistency to some degree. Although, there needs more supplementary studies, it is anticipated that landscape scale ecosystem evaluation using landscape indices can gives us some informations related to sustainable landuse planning.
GIS 와 다요소의사결정방법 ( MCE ) 에 의한 김해 대청공원 집단시설지구 적지분석

지리정보체계(GIS)에 의한 도면중첩방법은 지도화된 명목척도의 기준들에 대하여 적합한 위치를 찾는 문제에는 이상적인 방법이 될 수 있으나, 다수의 불명확한 기준을 가진 경우에는 많은 문제점을 안고 있다. 반면에, 다요소의사결정(MCE)기법은 다수의 결정요인을 가진 복잡한 위치결정의 문제를 푸는 좋은 방법이다. 이러한 GIS와 MCE의 결합에 의한 접근방법은 다수의 결정요인을 가진 적지분석을 합리적이고 객관적으로 수행하는 도구가 된다. 이러한 방법에 의하 Geographic Information System(GIS) overlay analyses, while for performing spatial searches on nominally criteria, are of limited use when multiple uncertian criteria are concerned. But,Multi-Criteria Evaluation(MCE) techniques offer a means of making comp

In order to reveal the geographical landscape's features of the East Sea-gateway(東海口), which has existed only in the era of Shilla as unique east path, we have carried out analysis of the old maps(邑誌圖) and satellite imagery, and geographical features analysis in the application of digital maps, and the result is as follows. 1. Analysis of materials from the Chosun dynasty describes landscapes called sea gates(海口) (note that this should not be capitalized); a place where the river meets the sea and the sea comes far into the land. Sea gate landscapes may have an island, but this is not a prerequisite. 2. According to the satellite imagery, the capital city of Shilla Dynasty had five passages. four or them are broad corridors, but one of them is narrow. The east side of the capital city is blocked by mountains and there was an important path which leads into the East Sea. 3. According to the cross section of the mountains, there is the only rule East-path. There was no alternative way. There was only one way-out to the east side from the capital city. This is the unique path which reaches a length of 28km. Judging from this, it seems that this path was called the East Sea-gateway. 4. The landscape of the East Sea-gateway was shaped like the letter 'V' and reached to the landscape of the sea gate. However, the route was blocked - part by the mountains, and also the part in the crisis of loss of path-landscape which has lost its own character of closure as several valleys are merged together.

The agricultural reservoir watershed plan suggests three specific indices or ways to measure the potential for maintaining reservoir quality in balance with existing or proposed uses: an index of the reservoir's vulnerability to accelerated eutrophication, an index of the degree of land use intensity in reservoir watersheds, and an index of present water quality. Three items that contribute to reservoir eutrophication are included in the vulnerability index: the ratio of reservoir volume to drainage-basin area, shoreline configuration, and mean depth. The watershed land-use intensity index is based on road proximity and upland watershed land-use intensity. Water quality can be given a COD level. All six indicators are considered separately and then rated as follow: low (1), medium (2), or high (3). Five out of 30survey sites were less than 8points, 17sites were less than 11points and 8sites were less than 14points. This study suggests that the sites in the first ranking were potential areas for preservation, sites in the second ranking were potential areas for environmental friendly planning and sites in the third ranking were potential areas for residential need oriented planning. The advantage of this study is the low cost of gathering data for the development of local policy for the planning, management and protection of reservoir basin.

본 연구에서는 토지정보체계(GIS)의 도형정보 처리를 위한 객체지향 데이타베이스를 개발하고, 이를 위하여 사용된 프로그램 개발방법을 설명하였다. 본 연구의 결과, 도형자료를 저장하고 관리하기 위한 자료모델을 개발하였으며, 개체지향 프로그래밍기법에 의한 도형자료 관리를 실현하였다. 도형자료 처리를 위한 자료모델을 개발함에 있어서, 관망해석을 하지않는 자료관리만을 목표로 하였기 때문에 위상학적(topology) 자료구조를 갖지않는 단순한 벡터모델을 사용하였다. 차후에 관거의 연결망을 기초로 하는 분석기능을 개발할 경우에는, 도형자료 처리를 위한 자료구조 부분에 대하여 수정 또는 추가 개발이 필요할 것이다. The purpose of this study is to develope on Object-Oriented Graphic database management system to handle geographic data of geographic information systems. As the result of this study, unstructured vector model was developed to handle geographic data and graphic database management was implemented by object-oriented programming. This study was focused on liking function between graphic data and attribute data, and not focused on network analysis function.
