| 摘 要： | 利用时间序列对比法分析了1961-2005年潮河流域降水、径流、用水量、水利工程、水土保持措施变化。结果表明：（1）自20世纪60年代以来，潮河流域年平均面雨量略有减少，但流域年径流量却呈明显减少趋势。1991-2000年的流域年径流量平均值为1961-1970年的90．9％，减少幅度较大；（2）潮河流域径流量的变化主要与水利水保等人类活动有关。利用降水一径流经验统计模型评估了流域水利水保措施对年径流量的影响程度：1981-1990年、1991-2000年、2001-2005年、1981-2005年，受水利水保措施影响所产生的年均减水量分别为1．15、0．28、1．10、0．79亿m^3，水利水保措施减水效应分别为31．99％、7．13％、40．71％、23．79％。水利水保措施对枯水时段的减水效应更为突出。 |

| Abstract: | Time series contrasting method is used to analyze the variation of precipitation, runoff, water consumption, water conservancy projects and soil and water conservation measures of the Chaohe River Basin from 1961 to 2005. The results show: (1) The annual precipitation in the drainage basin tends to decrease while the runoff has declined markedly since the 1960s, the mean annual runoff during 1991-2000 is only 90.9% in proportion to that of the period from 1961 to 1970. (2) The annual runoff variation in the drainage basin is significantly related to human activities such as soil and water conservation and hydraulic projects. The influence degree of engineering measures for water conservancy on runoff reduction is calculated by using the rainfall-runoff statistical model. The results show that during 1981-1990, 1991-2000, 2001-2005 and 1981-2005, the average annual runoff reduction amounts are 1.15 ×108, 0.28 ×108, 1.10 ×108 and 0.79 ×108 m3 respectively and the average annual runoff-reducing effects are 31.99% , 7.13% , 40.71% and 23.79% accordingly. Runoff-reducing effects by engineering measures for water conservancy are more prominent in the low water period. |
