松华坝水源地坡面水土保持林对水沙关系影响及其贮水能力分析
Influence of soil and water conservation forest on runoff and sediment's relationship and analysis of it's water storage capacity in water source slope at Songhua dam
摘要
Abstract
Through the analysis of the variation of runoff and sediment of Songhua dam water source,the paper used the LANDSAT TM remote sensing image of Songhua dam water source protection area from 1982 to 2010 and estimated the changes of soil and water conservation forest area in the basin for many years by using ENVI remote sensing inage processing method,and classified according to different slope.Through the comparison analysis of obtained data,it got the conclusion that sediment concentration of runoff and soil and water conservation forest coverage is exponential relation,the higher the degree of soil and water conservation forest coverage,the lower the sediment concentration of runoff.Using the deduction negative function method to calculate the actual water storage capacity of forest,it got the result that the average annual actual storage capacity of soil and water conservation forest in Songhua dam area is 113.44 million m3.关键词
