西部艰险地区水源地选址研究

为了在西部艰险地区实现军用水源地快速选址,选取地形、岩性、地貌及汇流累积量作为影响地下水富集的赋存条件因子,以土壤湿度、地表温度和植被覆盖度作为地表指示因子,以地貌作为军事防护因子进行研究。充分发挥利用遥感数据进行大范围水源地选址的优势,结合研究区地质资料进行图像解译和上述因子信息提取,建立具有不同层次结构的水源地选址评估指数模型。通过实地调查对模型进行验证,结果表明该评估指数模型预测结果可靠,适用于该地区军用水源地选址。

Study on site selection of water source in the perilous region of West China

In order to meet the need of efficient site selection of water source in the perilous region of West China, the study chose topography, lithology, landforms and flow accumulation as underground water enrichment factors in the study area. Soil humility, surface temperature and vegetation coverage were chosen as surface indicative factors. Landforms were also studied as the factor of military protection. Combining geological data and remote sensing images which have a great advantage in large-scale site selection of water source, the remote sensing images were interpreted and these factors data were extracted. And then the evaluation index model for site selection of water source was established. Through the field investigation for the model, the predictive results of the evaluation index model was correct. And the model can work well on site selection of water source for military in the study area.
