摘　　要：本研究针对现阶段我国集体建设用地分布在广大的集镇和农村,数量巨大、空间分布分散零乱、地形复杂,在全国范围内完全采用解析法获取大比例尺集体建设用地的空间数据,大部分地区不能承受为此付出的人、财、物之成本的特点,提出在全解析之外开展适合我国国情的集体建设用地信息采集、检查、入库、使用、管理和更新的技术。利用高分辨率影像采集集体建设用地空间数据,获取界址点坐标、界址边长、宗地面积;通过地籍调查和外业勘丈对建设用地空间数据进行检查纠错,同时,以村坊为单位建立建设用地属性数据;最终以村坊为单位对空间数据和属性数据进行关联,建立集体建设用地信息数据库。将该研究技术应用到试验区取得了较好的成果。In our country, an enormous amount of village constructive land is widely distributed in the market towns and large rural areas with dispersed and complex spatial land.It will pay a lot of manpower, financial and material resources that the analytical methods have used for obtain the large-scale of spatial data of collective building land across the country With this situation, the new technique methods very conducive, more suitable for our nation, to the collective building land spatial data for inspection, storage, using, management and update have been put forward in this paper, apart from the analytical method. First of all, we will collect the spatial data of land building to have the boundary point coordinates, boundary line length, and cadastral parcel area by using the high-resolution images. Secondly, the spatial land data will be checked and corrected by the cadastral inventory and tape measurement in the field; the attribute data of building land will be collected as a unit of the village administrative. Finally, the spatial data will be linked to the attribute data within one village administrative in order to set up the collective construction land database. This technique has been successfully applied at the test area with good results.
