Abstract: The methods of statistics,accumulated difference and the Kendall's rank verification were used comprehensively in this paper.The results showed that,in the Heihe River Basin,the annual precipitation is gently in general.In recent years,mean precipitation is lower than the average of long term's;the evaporation,which is relative stable,is bigger than the precipitation;the runoff varied dramatically from year to year,cut down notably,as the impact by precipitation and evaporation;the temperature daily amplitude is big and the accumulated temperature is of high efficiency.
