摘要
要使土地利用数据库的成果在土地资源管理的模式优化方面取得显著成就,必须定期革新数据源。以靖边县为对象,对县级土地利用数据库数据的收集、数据源的确定、数据处理和数据库的建设,采用地理信息系统技术进行设计和评价。对土地利用现状调查成果转换成土地利用数据库数据过程中信息损耗最小的技术方法和工作流程进行了探索。
The database of land use can provided more accurate and more scientific decisive information for the optimal management model of land resource if only spatial data origins are renovated periodically. In the process of constructing land use database in Jingbian County, the data collection, the decision on spatial data origins, the data handling to the construction of land use database are planned and evaluated based on GIS at county level. The flow diagram and the techniques of the work to minimize the information loss in transforming from the investigation result at present land use to the land use database are studied with the help of GIS.
