柴达木盆地水资源信息系统研究

Study on the Water Resources Information System in Caidam Basin

以地理信息系统为工具 ,集成了相关的图形、图像、报表、文档等数据和以往的研究成果 ,建立了柴达木盆地水资源信息系统。系统具有友好的界面和便利的查询、检索功能。在此基础上 ,分析了雨量站的空间分布、降水量与高程的关系及通过数字高程模型 (DTM)的降水量空间插值 ,提出了降水水资源沿河开发域。

With GIS, the relative maps, the phots, the tables, the documents and the data are integrated into a water resources information system which possesses the ability of friendly interfaces and convenient index. Based on this, the special distribution of the precipitation stations, and the relationship between the precipitation and the terrain in the basin are analysed. Last, the water resources exploring area along the river in Caidam Basin is presented.
