降水一水土保持一径流统计模型在潮河流域的应用
Application of a Rainfall-Soil and Water Conservation-Runoff Statistical Model in Chaohe River Basin
摘要
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 runoff-reduction 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.关键词
