摘  要：
[目的]分析天然降雨条件下,裸坡、植被坡的产沙产流特征。[方法]以10°、15°裸坡和植被坡为试验对象,分析了裸坡、植被坡在天然降雨条件下的产沙产流特征,以及裸坡与植被坡的降雨量与产沙量关系。[结果]裸坡与植被坡的产沙量、产流量都与降雨量、坡度、坡面植被有关。各坡面累积产沙量、产流量的大小关系均为15°裸坡>10°裸坡>15°植被坡>10°植被坡。天然降雨情况下,各坡面产沙量与降雨量均呈幂函数关系。[结论]在相同坡度条件下,植被坡的产沙量、产流量都比裸坡要小,说明其具有较好的水土保持效应。

摘  要：
[Objective] The research aimed to analyze generated characteristics of sediment and runoff on bare and vegetation slopes under natural rainfall condition.[Method] 10° and 15° bare and vegetation slopes were the test object.The generated characteristics of sediment and runoff on bare and vegetation slopes,relationship between rainfall and sediment amount under natural rainfall condition were analyzed.[Result] The sediment and runoff amounts of bare and vegetation slopes both related to rainfall,gradient and vegetation.The relationships of accumulated sediment and runoff amounts on each slope were all 15° bare slope>10° bare slope> 15° vegetation slope>10° vegetation slope.Under the natural rainfall condition,the sediment amount on each slope and rainfall all presented power function relationship.[Conclusion] Under the same gradient condition,the sediment and runoff amounts of vegetation slope were smaller than that of bare slope.It illustrated that vegetation slope had good water and soil conservation effect.
