摘要

集水區在整治上常面臨不同治理目標的衝突或權衡（trade-off），而一般傳統單目標決策方法並不能兼顧多方面的要求，提供選擇的資訊；多評準決策方法（MCDM）則可提供在有限資源之條件下，提供一兼顧各目標之滿意解。有鑑於此，本研究以地理資訊系統與遙感探測等技術輔助萃取研究範圍－新草嶺潭集水區之相關空間資訊，結合應用多評準決策之PROMETHEE方法對研究範圍區內41個子集水區進行其優先整治區域之評選分析，期建立一客觀評估模式以供主管機關於集水區整治規劃時之參考。

The management of watershed often encounters with conflicts or trade-off among objectives. While traditional single objective decision techniques fail to provide alternatives information in the way of multiple objectives, multiple criteria decision making (MCDM) measures can provide a satisficing solution for compromising all the objectives under the constraint of finite resources. Therefore, this study applied GIS (Geographic Information Systems) and RS (Remote Sensing) techniques to extract related spatial information for New Tasoling Lake watershed, and integrated them with MCDM PROMETHEE method to proceed spatial priority assessment analysis for 41 sub-watersheds for the study area. The goal of this study is to establish a multi-objective evaluation model as consultation reference to decision managers for watershed management.
