| 摘 要： | 以海河水系唐河上游流域为研究对象,根据1960年-2002年流域的降水及实测径流资料,利用肯德尔秩次相关法和双累积曲线,分析了年降水、年径流和降水-径流关系的变化趋势.结果表明,降水量不存在明显变化趋势,而径流量存在明显的下降趋势.整个降水-径流系列可以划分为三个阶段:1960年-1978年,1979年-1995年,1996年-2002年,三个阶段的降水-径流相关系数依次减少,降水-径流相关性减弱.此外,从流域内土地利用类型变化、水利工程建设、地下水资源开发利用状况等几个方面对流域降水-径流变化原因进行了初步分析与评价. |

| Abstract: | Kendall method and double mass curve are applied to analyze the variation trend of annual rainfall,runoff and rainfall-runoff relationship in the upper Tang watershed in the Haihe River Basin from 1960 to 2002. The result showed that the annual rainfall series had not a visible downtrend but the annual runoff series had an obvious downtrend. The whole rainfall-runoff series could be divided into three periods: 1960~1978,1979~1995,1996~2002. The correlation between rainfall and runoff kept weakening,as its c... |
