全国河流信息分布图的编制

Compilation of National Rivers Information Distribution Map

为直观地表现全国河流密度分布信息,将经过分析和统计的,以县或水资源三级区为单位的河流密度成果,选用Map GIS软件,结合全国行政区划图和水资源分区图编制全国河流信息分布图,对全国河流信息分布图编制的流程做较详细的阐述。本图编制采用的资料较齐备,成果满足全国中小河流治理规划等水利专题规划工作的需要。

In order to show the national rivers density distribution directly, combining with the national administrative zoning map and water partition map, the article uses the analysis and statistics of the rivers water density results of every county or water resource level 3 partition units to compile the national rivers density distribution map by Map GIS. It introduces the national rivers density distribution map compiling process in detail. Data used in distribution map is completed. The results meet the needs of the national small and medium-sized river management plan and other water conservancy projects.
