| 摘 要： | 为了科学预测浑河流域降水对径流的影响，利用浑河流域1956—2011年56年的逐月降水与径流资料，借助累积距平、滑动平均等方法分析了浑河流域降水量与径流量的变化趋势及时间尺度上的相关性。结果表明:（1）浑河流域降水集中在6—9月（7月最大），径流集中在7—8月，且流域降水年内分配的不均匀性由上游至下游逐渐递增，而径流年内分配的不均匀程度总体呈现由上游至下游逐渐减小的趋势。（2）浑河流域降水量与径流量的相关系数为0.682，累积距平曲线和滑动平均曲线均显示浑河径流量与降水量的年际变化趋势是一致的，70年代之前好于70年代之后，丰水年份好于枯水年份。结合累积距平曲线和滑动平均曲线分析得出浑河流域降水量和径流量具有较高的相关性，可为浑河流域水资源的可持续利用及区域社会经济的永续发展提供科学依据。

| 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. |
