摘要
选用渭河流域主要控制站径流资料,分析了径流量的时空分布特性及其变化情势,探讨了20世纪90年代以来渭河径流量减少原因,为水资源合理开发、高效利用及系统规划提供科学依据。
In this paper, the runoff data from the main eontrol gauges on the Weihe River are analyzed for runoff char- acteristics, spatial-temporal distributions and changing trend. The cause of runoff reduction of the river since 1990 is explored so as to provide a scientific basis for the rational development and effieient utilization of the basin＇s water resources.
