摘要

以密云水库以上的潮河流域作为研究区域，对流域1961-2005年的还原年径流量、年降水量、年水土保持措施(水平梯田和造林)面积数据进行了多元回归分析。建立基于降水-水土保持-径流之间关系的统计模型，定量评估了该区水土保持措施对流域年径流量的影响程度。模型评估结果表明，1961-1970年，1971-1980年，1981-1990年，1991-2000年，2001-2005年，流域水土保持措施的年均减水效应分别为2.54%，3.52%，28.71%，6.87%和48.02%;1981-2005年，流域水土保持措施的年均减水效应比较显著为22.96%。2001-2005年的年均减水效应最大，1981-1990年的年均减水效应次之，1991-2000年的年均减水效应最小。水土保持措施对枯水时段的减水效应更为突出。

Abstract

Taking the Chaohe River Basin above the Miyun Reservoir as a study area

the influence of soil and water conservation measures on annual runoff was assessed quantitatively by the rainfall-soil and water conservation-runoff statistical model established on the basis of multiple regression analysis using historical annual runoff

annual precipitation and areas of soil and water conservation measures in the drainage basin during 1961-2005.The results showed that during 1961-1970

1971-1980

1981-1990

1991-2000 and 2001-2005

the average annual runoff-reduction effects were 2.54%

3.52%

28.71%

6.87% and 48.02%

respectively

with an average of 22.96% during 1981-2005.The average annual runof-freduction effect was the greatest during 2001-2005

intermediate during 1981-1990

and the smallest during 1991-2000.The runoff reduction effects of soil and water conservation measures were more profound in the drier period.
