【Abstract】 In this paper,the runoff data from the main control gauges on the Weihe River are analyzed for runoff characteristics,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 efficient utilization of the basin’s water resources.更多还原
