摘　　要：地籍测量中宗地数据以AutoCAD的图形文件格式(*.dwg)为主,其中宗地属性以闭合多段线的扩展数据(XData)存储。目前,宗地属性的录入一般以南方CASS软件的模式窗口逐条录入,当宗地数据量增加时,该过程显得过于繁琐,如果能从Excel直接批量导入,可以解决该问题。文中以乐山市马边县的房屋宅基地调查为例,借助Excel对宗地数据的预处理,利用C#对AutoCAD进行二次开发,最终实现自动添加宗地编码,批量导入宗地属性。实践表明,该方法的处理效率较高。The parcel data in cadastral survey takes AutoCAD graphics file format （ ＊. Dwg） as the main which attributes are in a closed polyline extended data （XData） memory. At present, the entry of the parcel attributes generally allow the South CASS software mode window one by one, when the parcel increases the amount of data the process is too cumbersome. If the bulk import is directly from Excel, the problem will be solved. Taking the housing homestead survey as the example, in Mabian Country of I.eshan City, and with the help of Excel parcel data preprocessing, C# is used for secondary development of AutoCAD to obtain automatically added parcel coding and import parcel attributes. Practice shows that the method of processing is of the efficiency.
