MAPGIS在甘肃省矿山地质环境分区中的应用
|
摘要
在MAPGIS技术支持下,采用综合指数模型,将各影响因素按其权重进行空间代数叠加,根据叠加的结果并结合综合评估指数的大小将甘肃省的矿山地质环境分为3级区.其中:严重区23个、较严重区22个、一般区1个,分别占全省总面积的2.731%,7.380%和89.889%.
The grid layers were combined with a weighted linear equation using map overlay to obtain a map indicating the quality of a mine's geological environment using the MAPGIS.The resultant grid map was categorized into three classes:severe,relatively severe and moderate,and then vectorized into a vector map. It is found that in Gansu Province,the zoning number and area percentages indicating that the geological environment of mines is severe are 23 and 2.731%,respectively,the zoning number and area percentages indicating that the geological environment of mines is relatively severe are 22 and 7.380%,respectively,while the zoning number and area percentages indicating that the geological environment of mines is moderate are 1 and 89.889%,respectively.
