宁夏草原实验站地区生态地质环境脆弱 ,土壤侵蚀 ,土地沙化 ,水质恶化等地质灾害现象较严重。为了提高全民保护和改善地质环境的意识 ,帮助政府部门制定环境管理和地区开发政策 ,利用模糊加权评价的数学模型 ,借助 GIS空间分析技术 ,对来自于多渠道的地质环境信息进行了综合分析 ,将研究区地质环境质量分为差、较差、中等、较好、良好 5个等级 ,并制作了地质环境质量综合评价分区图 。
The complex assessment of geological environment is a main part of environment evaluating. The ecology geological environment in Caoyuanshiyanzhan area is very vulnerable with severe hazards such as soil erosion, land sanded and water deteriorated. In order to improve people's idea of protecting geological environment and help the governmental department make more reasonable policies of environment management and regional development, in this paper, the Fuzzy method is used with the spatial analysis techniques of GIS, the geological environment information from various sources is analyzed, and the quality of geological environment in study area is ranked as five ranks from good to bad. It also describes the characters of zones and provides some remedial suggestions.
