摘　　要：宁夏沿黄经济区是我国西北地区重要的工农业生产基地,同时又是带动宁夏回族自治区及周边地区国民经济发展的重要核心地区。本文利用层次分析法建立了区域生态地质环境质量评价指标体系;基于ArcGIS平台,将GIS技术应用于研究区基础资料的数字化处理,建立了生态地质环境质量信息数据库及基本图层;并针对宁夏沿黄经济区的实际特征建立了相应的分级标准,对该区的生态地质环境质量进行了评价与分区。评价结果表明:宁夏沿黄经济区生态地质环境质量分为优、良、中、差四个等级,其中优区面积约为370km2,占全区总面积的4.5%;良区面积为2 307km2,占全区总面积的28%;中区面积为2 959km2,占全区总面积的35.9%;差区面积为2 606km2,占全区总面积的31.6%。该研究结果对治理改善该地区的生态地质环境具有重要的指导意义。Economic zone along the Yellow River in Ningxia Hui Autonomous Region is an important industrial and agricultural region in northwestern China.It is a key area of leading economic development for Ningxia Hui Autonomous Region and its surrounding areas.The index system of quality assessment of regional geological eco-environment is established by applying Analytic Hierarchy Process（AHP）.Based on ArcGIS software,this paper applies GIS to the pre-processing of basic data and setting up database and basic layers of geological eco-environmental quality.According to the classification standard,the quality of geological eco-environment in the study area is evaluated and moreover the distribution is obtained.The result indicates that the geological eco-environmental quality can be divided into four classes as excellent,good,fair and poor.The four areas are 370km2,2 307km2,2959km2 and 2 606km2 respectively.The excellent,good,fair,poor areas take up 4.5%,28%,35.9%,and 31.6% of the total area respectively.
