基于ArcGIS的高放处置库粘土岩预选区的评价研究

Evaluation of Pre-selected Area of Clay Rock in High-level Disposal Depot Based on ArcGIS

在高放处置库选址实际上是一个对各关键要素叠加分析与比较的过程。文章采用ArcGIS对中国高放处置库西北地区粘土岩预选区进行研究,从处置库选址的经济社会条件与自然地理条件出发,分别对阿拉善右旗人口密度、土地条件、矿产资源等七大因素进行叠加分析,得到预选区经济社会条件与自然地理条件评价结果,并得到选址的理想范围,为高放处置库粘土岩预选区的选址提供科学的方法和量化的评价标准与结果。

The location of a high-level repository is actually a process of superimposing and comparing key elements.In this paper,ArcGIS is used to study the pre-selected area of clay rock in the northwest of China s high-level depot.Starting from the economic and social conditions and natural and geographical conditions of the site selection,the population density,land conditions and mineral resources of Alashanyou Banner are respectively selected.The factors were superimposed and analyzed,and the results of economic and social conditions and natural geographical conditions in the pre-selected areas were obtained,and the ideal range of site selection was obtained.The scientific methods and quantitative evaluation criteria and results were selected for the site selection of the pre-selected areas of high-level depots.
