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 the help of GIS, the related graphic, image, report, document and other data and the previous research results have been integrated, and a water resource information system of the Qaidam Basin has been established. The system has a friendly interface and convenient query and retrieval functions. On this basis, the spatial distribution of rainfall stations, the relationship between precipitation and elevation, and precipitation space interpolation of digital elevation model (DTM) are analyzed.
