| 摘 要： | 影响拉萨市浅层地温能地质环境质量的因素主要有地质环境背景、第四系及含水层因素、水量环境因素、水质环境因素等四大类,对四大类影响因素及其下一级因子进行层次分析和模糊数学模型的构建,确定其隶属度函数,计算各因子的权重值。利用GIS的属性赋值与空间分析,对地质环境质量评价区进行网格划分,计算出各网格单元的模糊质量指数值,绘制了模糊质量指数等值线,在此基础上对拉萨市浅层地温能地质环境质量进行了评价。

| Abstract: | This paper has a discussion on the application of fuzzy comprehensive evaluation method to the geological environmental assessment during development of the Lhasa Geothermal Field. Quality of geological environment is affected by geological setting, Quaternary, aquifer, water content and quality. The geological environment quality assessment areas are divided into cells by means of attribute assignment and space GIS, fuzzy quality indexes for each cells index are calculated and fuzzy quality index contour lines are drawn. Accordingly, a fuzzy mathematical model is established in order to assess quality of geological environment during development of the Lhasa Geothermal Field. |
