- 摘要:
- 台湾省的土地资源非常有限，山地面积占73.65%，平地仅占26.35%，由於人口急速膨胀，大量向都市集中淤是都市范围不断扩张，使得广大山坡地成为重要开发之目标。本省山地约占2/3，因地形起伏大，加上降雨集中，一遇豪雨，雨水所汇集之迳流即流入溪流，迅速排出，无法渗透至地下，故集流时间短、洪峰流量大，成为台湾水文环境之特性。在资源有限，自然环境欠佳，而各种森林资源之开发、农地之利用、人口居住又面临迫切的需求下，如何兼顾资源的开发与保育，避免两者之间的冲突，集水区水资源的开发与划定亦是重要的课题之一。水里溪集水区位於台湾省中部，属浊水溪中游之水系，面积约7400hm2，包括明湖、明潭、日月潭等三个水库及钜工调整池。由於区内交通方便，游客众多，观光事业发达；另一方面，因本集水区的气候、土壤适宜栽种摈榔等经济作物，在有厚利可图的情况下，集水区内的土地纷纷改种槟榔，近年来更有大量种植的趋势，使得森林的覆盖减少，造成生态环境、微气候的改变，并对当地的水土冲蚀、水质、水量产生影响，故对於集水区的经营与管理，需有一合宜的监控模式。本集水区的环境日益恶化，究其原因乃为土地利用之改变，故本研究即利用遥测影像加以判释，了解其土地利？
- Abstract:
- Taiwan has a limited land resources where flat land area counts for only one fourth of the total land area.Due to the population increase and economic growth, the urbanization movement has expanded to slope land and even mountain side development.From nature geology point of view 4 the land of Taiwan consists of short run -off path and high peak flow because of dramastic surface relief and huge amount of precipitation.which two or three events of typhoon would bring into.There is a conflict between slopeland resources development and preservation especilly at watershed area.Shut-li River watershed locates at the center of Taiwan consists the area of 7400 hectare.Three reservoivs with power plants, one amendment ponds, and a tourist attraction sites were also inside this watershed.Climate condition and deep soil are Suitable for cash crop growth in the watershed area.Banboo and Pinang (Areca cutechu L.) has been developed as the major vegetations alo ng this slope land where were restricted as preserved area and caused concern about soil erosion and fertilizer pollution problem.This study used Geographic Information System (GIS) technique to collect watershed database and to combine with satellite image classification for land use suitability analysis.This results can then link with other hydrology and socio -economic model to develop an integrated watershed land use monitoring strategy for better decision making and for resources sustainability.
