Every year, Taiwan endures typhoons and earthquakes; these natural hazards often induce landslides and debris flows. Therefore, watershed management strategies must consider the environmental vulnerabilities of local basins. Because many factors affect basin ecosystems, this study applied multiple criteria analysis and the analytical hierarchy process (AHP) to evaluate seven criteria in three phases (geographic phase, hydrologic phase, and societal phase). This study focused on five major basins in Taiwan: the Tan-Shui River Basin, the Ta-Chia River Basin, the Cho-Shui River Basin, the Tseng-Wen River Basin, and the Kao-Ping River Basin. The objectives were a comprehensive examination of the environmental characteristics of these basins and a comprehensive assessment of their environmental vulnerabilities. The results of a survey and AHP analysis showed that landslide area is the most important factor for basin environmental vulnerability. Of all these basins, the Cho-Shui River Basin in central Taiwan has the greatest environmental vulnerability.
每年台湾都会遭受台风和地震的侵袭，这些自然灾害常常导致山体滑坡和泥石流。因此，流域管理策略必须考虑当地流域的环境脆弱性。由于许多因素会影响流域生态系统，本研究应用多标准分析和层次分析法（AHP），在地理、水文和社会三个阶段对七个标准进行评估。本研究以台湾五个主要流域为重点：淡水河流域、大甲河流域、浊水河流域、曾文河流域和高屏河流域。目的是全面考察这些流域的环境特征，并全面评估其环境脆弱性。调查和 AHP 分析的结果表明，滑坡面积是流域环境脆弱性的最重要因素。在所有这些流域中，台湾中部的浊水河流域环境脆弱性最大。
