摘　　要：为满足藏北高原地区给水站快速选址的需求,从该区气象水文、地质环境和地貌条件出发,对给水站选址的遥感多指标评价模型进行了优化,减小了模型复杂度和遥感信息提取的工作量。采用模糊评价算法对各指标进行规范化,构建高原地区给水站选址多指标评价模型;采用加权合成算法计算给水站选址评估指数。研究区实地勘查表明,选址评估指数的验证结果与理论分析结果一致,该模型在高原地区给水站选址中具有较好的应用效果。In order to meet the urgent need of water supply site selection in North Tibetan Plateau, this study opti-mized the remote sensing multi-index evaluation model for water supply site selection by meteorology and hydrolo-gy ,geological environment and landforms in the study area. Also the model complexity and the worklood of remotesensing data extraction were reduced. The study utilized the fuzzy evaluation algorithm for normalizing each factor,and then constructed the multi-index evaluation model for water supply site selection in plateau. Finally, the eval-uation index of water supply site selection was calculated by weighted synthesis algorithm. The prediction of theselection evaluation index was consistent with theoretical analysis through the field investigation in the study area. Therefore, the model can work well for water supply site selection in plateau.
