摘要:
为进一步探讨森林植被对流域坡地不同尺度降雨产流产沙的影响，为黄土区植被建设提供理论依据，对蔡家川流域坡面径流小区和试验小流域降雨产流产沙进行了测定和分析.结果表明，坡面自然更新的次生林和虎榛子灌木林较人工林有更好的涵养水源、保持水土功能;通过灰色关联分析，林分郁闭度和草本、枯落物生物量对坡面产流产沙影响显著.在对嵌套流域聚类分析的基础上，相似地形地貌的子流域，少林流域比多林流域的雨季径流深和径流系数高2.7～2.9倍，且前者暴雨径流输沙量是后者3～6倍.
Abstract:
In order to study deeply the relationship between vegetation and runoff and sediment production in sloping lands at different scales,and to provide theoretical basis for vegetation re-construction of loess area,the runoff and sediment production were observed and analyzed which produced in runoff plots of sloping lands and testing catchment in Caijiachuan watershed which lies in Jixian county of Shanxi Province in Loess area.The results showed: 1) the natural-secondary forest and Ostryopsi sdavidiana forest had better function of soil and water conservation than man-made Robinia pseudoacacia forest.2) Based on gray correlation analysis to kinds of factors affecting runoff and sediment production in sloping land,the factors of stand canopy density and herb and litter biomass were the most significant ones.3) Forested watershed and rangeland watershed with similar terrain and topographical features were selected by using the method of cluster analysis to nesting Caijiachan watershed.It clarified that runoff depth and runoff coefficient of less forest watershed were 2.7~2.9-fold as much as those of more forest watershed.And sediment yield produced from less forest watershed by storm was 2~5-fold than those from more forest watershed.
