基于层次分析法确定权重的地质环境质量评价——以乌蒙山重点贫困地区喜德县、昭觉县交界区域为例

Geological Environmental Quality Evaluation Based on Analytical Hierarchy Process to Determine the Weight——By the Example of Xide-Zhaojue Border Region

以四川喜德县与昭觉县交界区域为研究区,以1:5万水文地质调查成果为基础,建立起地质环境质量评价指标体系。运用遥感、水文钻、地球物理、水文地球化学等手段,量化分级评价体系指标,确定体系中不同层次指标权重,用GIS软件对研究区地质环境质量分区及评价。结果表明,研究区92.38%的区域地质环境质量较好,而区内两河口镇、沙马拉达乡、巴久乡等人类工程活动强烈区域,地质环境质量较差,这与研究区实际现状相符。研究成果可为乌蒙山重点贫困地区推进区域精准扶贫,实现区域人口、环境和资源协调发展提供技术支撑。

A geological environmental quality evaluation system is established based on 1：50 000 hydrogeological survey in the Xide-Zhaojue border region and GIS and analytical hierarchy process to determine the weight by means of remote sensing, hydrogeological drilling, geophysical and geochemical data. The results indicate that area of good geological environment quality makes up 92.3% of total area of the studied area, while geological environment quality in the region with strong human engineering activities is poorer.
