在二调数据库中统计指定范围内地类面积的方法

THE METHOD OD LAND AREA STATISTICS WITHIN THE SPECIFIED RANGE IN DATA BASE FROM THE SECOND NATIONAL LAND SURVEY

全国第二次土地调查数据库利用以后,城市建设用地审批、大型的线状用地、土地复垦、矿山治理等工程的前期可研及预审工作等基本都以二调数据为基础数据。将正确的用地红线用ArcGis软件处理成面文件(.Shp),然后把处理后的.shp文件复制到二调数据库里的KCDJ层里。再使用农村土地调查专用软件导出各级用地面积汇总表。通过文中介绍的方法,可以实现快速、准确的制作指定范围的各种地类面积表。

After the second national land survey, the preliminary feasibility study and prejudication of some projects （such as granting urban development land use right, large liner land, Land reclamation and mine management） are based on the data from the second national land survey. This paper introduced how to use software such as ArcGis. Cass and Guotu to analyze the land type within the specified range and export the summary sheet of all levels of land area. Through the method introduced in this paper, all kinds of land type sheet can be produced quickly and accurately.
