GIS支持下的矿山开采土地损害评估与分析

Mining Land Damage Assessment and Analysis Based on GIS

主要分析了矿区开采沉陷对土地利用变化影响,把矿井范围内的开采沉陷数据和土地利用现状图进行GIS入库,统一到ArcGIS平台下。把沉陷区转变成各沉陷深度的面状图层,并与土地利用现状图中的各种土地利用类型相叠加,通过空间分析得出开采沉陷影响各种土地利用类型的范围和准确影响面积,结果以图的方式反映到GIS平台上,最后对所得的数据进行统计分析。

This paper mainly analyzes mining subsidence’s influence on land use by using GIS,puts data of mining subsidence and layer’s data of land use into ArcGIS,changes region of mining subsidence to regions of the different deep subsidence,and intersects layers of mining subsidence with one of land use.The different deep subsidence and land use database are spatially analyzed and the different lands are found out and their areas are calculated.In the end the obtained data are analyzed statistically.
