| 摘 要： | 大流域区划数据是反映水资源分布的重要数据,也是土地利用总体规划和农业结构总体规划所必需的重要基础数据。针对当前没有与北京市土地利用现状数据一致的大流域区划数据,参照北京市已有的流域划分数据与方案,以DEM和SPOT5遥感影像为基础数据源,通过GIS数据处理、水文特征分析与流域划分等生成北京市五大流域区划数据;通过三维景观图等对大流域界线进行调整,重新勘定北京市大流域界线。

| Abstract: | The data of Beijing large watershed which reflect water resource distribution are the important data to the land use global planning and agriculture global planning.In allusion to the absence of large watershed map data which are accordant with Beijing land use status data,the borderline of Beijing large watershed is re-delineated in this paper.The historical watershed data and solution are referenced and the DEM(digital elevation model) and SPOT5 remote sensing image are chosen as base data resources.The five large watershed map data are gotten through GIS data processing,hydrology feature analysis and watershed division.Moreover,local adjustments with the means such as 3-dimensional view are done.At last,this paper presents important base data to the editing and adjustment of Beijing land use global planning. |
