【摘要】For calculating land damage degree in the coal mining subsidence area,the Python that attached to ArcGIS,a script language compilation software,were used to predict the land damage degree area of every land use type.Land damaged degree result characterized as the SHP file format can be outputted directly and then the predicted figures of land damaged can be obtained,through the way that the subsidence contour,additional tilting contour and horizontal deformation contour files with DWG format and the land use file with SHP format were inputted altogether in the Py-thon software.The satisfactory result was obtained from SanYuanJiXiang Coal Mine.Therefore,the software can be applied directly to calculate land damaged degree in other coal mining subsidence area.It is promoted easily and conven-ient for the application of basic technician.%为计算井工煤矿采煤沉陷区土地损毁程度，利用 ArcGIS 的 Python 脚本语言编制软件，实现通过输入相同坐标系的下沉等值线、附加倾斜等值线及水平变形等值线3个 DWG 格式文件和土地利用现状 SHP 格式文件，直接输出土地损毁程度的 SHP 格式文件，从而获得沉陷区土地损毁程度预测图。通过对三元吉祥煤矿的实例分析，该软件亦可直接用于其他井工煤矿开采沉陷区土地损毁程度计算，且方便基层技术人员使用和推广。
