北洛河流域近期水沙变化原因水文分析
Hydrological Analysis for the Cause of Recent Change of Water and Sediment in the Beiluohe River Basin
摘要
Abstract
Based on the analysis of the characteristic of natural environment, soil and water conservation in the Beiluohe River Basin, using the data on rainfall, runoff and sediment, the paper established a statistic model for the runoff and sediment under rain, and analyzed the cause of water and sediment change in the basin. The results showed that the sediment reduction of the Beiluohe River Basin is mainly in the upper reaches of the Liujiahe Station, in which the human activities accounted for about 60%, and rainfall effects for 40%.The large amount reduction of runoff took place mainly in the lower reaches of the Liujiahe Station, from the comparing between human activities and rainfall effects, the rainfall effects accounted for about 60%～70%, and the human aceivities for about 30%～40%.关键词
