Abstract
This study developed an ecological mapping technique with GIS database using the analyses of existing ecological survey reports and the change detection on the Nakdong river estuary. The data which are used to establish GIS DB include 2 Landsat TM images on Nov. 31, 1984 and May 17, 1997, 1:25,000 topographical maps established by National Geography Institution and various ecological survey reports published by Busan metropolitan city government. The details for producing ecological map are as follows. At first, the current methods of ecomapping efforts and previous ecological surveys of Nakdong river estuary were carefully examined. Secondly, the land cover maps were created from the classified Landsat images of 1984 and 1997 for the spatiotemporal ecosystem analysis. Thirdly, the ecosystem was evaluated by using GIS ecological database based on the criteria of botany, zoology and water quality etc. Each criteria was reclassified into 3 stages which describe the overall quality of ecological condition. At last, the comprehensive ecological map was suggested as a prototype of ecosystem assesment and management tool with the discussion of further study. The findings of this study would be a milestone for preserving and managing the ecosystem.
본 연구는 낙동강 하구 일대의 생태계 변화와 생태 관련자료를 GIS DB로 구축하고 생태지도를 작성하였다. 생태지도 작성을 위해 1984년 11월 21일, 1997년 5월 17일에 촬영된 공간해상도 30m의 Landsat TM 위성영상과 국립지리원에서 발행된 1:25,000 수치지형도, 부산시에서 조사한 생물현황 자료를 바탕으로 DB를 구축하였다. 생태지도를 작성하기 위해, 첫째, 낙동강 하구 생태계 조사 보고서와 현재까지 진행된 생태지도에 대한 문헌 연구, 둘째, 시계열적 토지피복분류도 제작, 셋째, 동 식물상, 수질 등 생태계 항목별 DB 구축과 3단계 방식에 의한 생태계 평가, 최종적으로는 이러한 분석 결과를 바탕으로 생태계 관리를 위한 생태지도를 작성하였다.
