- Abstract:
- To forecast the effect of precipitation on runoff scientifically, the change trend and the correlation time scales of basin precipitation and runoff in Hunhe River basin are analyzed with the help of accumulated anomaly and 5-year moving-average method based on the monthly data of precipitation and runoff in Hunhe River basin within 56 years(1956—2011). The results showed that: (1) the precipitation and runoff concentrated from June to September (especially in July)， and runoff concentrated from July to August, the precipitation inhomogeneity increased gradually from upstream to downstream within a year, but the non-uniform of runoff decreased from upstream to downstream; (2) the correlation coefficient between precipitation and runoff in Hunhe River basin was 0.682, both the cumulative departure curve and moving average curve showed that the inter-annual variation trend of runoff and precipitation in Hunhe River basin were consistent, and the trend was more obvious after 1970s than before 1970s, more obvious in wet years than in dry years. The conclusion of runoff highly correlated with the precipitation is presented, which can provide scientific basis for the sustainable utilization of water resources and regional society and economy sustainable development in Hunhe River basin.
