本計畫運用地理資訊系統及統計分析方法,整合相關地形與地質資料,分析各種潛在因子及不同促崩因子之基本特性、各因子與崩塌地間的關聯性及因子間的相依性等,找出關鍵因子暨各因子的內部評分及因子間的權重,建立山崩潛感分析模式並進行山崩潛感分析,分年編製各區相關成果圖。計畫全程共三年。第一年工作主要為方法學回顧與分析模式建立,並選擇現有資料較為豐富的台灣中部國姓地區進行初步測試,研究成果顯示本研究所選用的判別分析方法優良,所建立的分析流程務實可行。第二年研究先將前一年度在國姓地區的分析成果運用於其北鄰之東勢地區,瞭解其可行性,並選擇台北地區做分析模式之進一步測試,同時進行設計雨量及設計地震之初步分析。本年度 (第三年) 再於台灣東部及西南部各選一試驗區做最後驗證,進行三年研究成果之總檢討,確定山崩潛感分析方法及工作準則,完成總報告。 This study utilizes a geographic information system and the statistical method to integrate geomorphic, geologic and relevant data, and to analyze the basic properties of each landslide potential factor and the triggering factor. The statistical method was used to make clear the correlation of each factor with the actual landslides, and to realize the dependency among factors. Several important factors were then selected for further analysis. Rating was done for each selected factor, and weighting between factors was determined according to a proper analytical method. The landslide susceptibility analysis was actually performed at several test sites, and a susceptibility map for each test site was made as the work progressed. 研究期間:9402 ~ 9412
