摘要
该文介绍的土地资源信息系统是建立在大比例尺资料基础上,并直接为基层生产单位服务的专业性地理信息系统。通过对以地块为单元的各种要素数据进行采集、贮存、分析、变换、综合等项处理,可完成土地资源清查、质量评价、动态分析、优化利用以及规划预测等项任务。应用结果表明,该系统对于小流域水土保持综合治理有重要的意义。
Land Resources Information System of Shanghuang presented in this paper is based on data from big scale infrared aerial photographs,thematic maps, field experiment and investigation.It is oriented to application for grass- roots organizations directly.Resources inventory,capability evaluation,Landuse optimization and modelling are undertaken on the basis of field patches.36 features of each patch were collected,including geography,climate,soil, current use and soil conservation measures.Primary application showed this system is very useful for small catchment management of soil conservation.
