面蚀

雨强29.7mm/h时主要以面蚀为主，产沙起伏3次。

When the rainfall density is 29.7mm / h , the erosion is primarily the surface erosion and there are three fluctuations in the process of sediment production .

累积面蚀量和细沟累积侵蚀量均随降雨时间的延续而增加，且后者增加幅度明显大于前者；

Accumulated sheet and rill erosion amounts increased with the rainfalls time , and the latter increased quickly than the earlier .

试验结束时细沟侵蚀量分别为面蚀量的4～5倍。

At the end of the rainfalls , the total rill erosion amounts are 4.3 and 5 times more than in sheet erosion .

坡面侵蚀过程可以明显分为面蚀、细沟发育和细沟稳定三个阶段。

The soil erosion process on the slope was clearly divided into sheet erosion stage , rill erosion developing stage and rill erosion stable stage .

研究结果表明，降雨初期坡面以面蚀为主，细沟出现后，坡面侵蚀将加快加剧；

The results indicate that the main erosion type is sheet erosion at the beginning of the rainfalls , and serious erosion happens after rill erosion appeared .

降雨结束时，坡面细沟累积侵蚀量约为累积面蚀量的2.5～5.5倍，约占坡面总侵蚀量的80%以上。

The total accumulated rill erosion amounts were 2.5 and 5.5 times more than accumulated sheet erosion amounts . The rill erosion amount contributed 80 % to the total erosion amount on the slope .

产沙最与降雨量加径流深组合因子成正比相关，并随坡度增大而增加，坡度超过25&28度水流面蚀强度减弱。

Soil erosion is proportional to the addition of precipitation and the depth of runoff and increases with the gradient of the ground surface , while the runoff flow erosion decreases on the slope of over 25 ° - 28 ° .

结果表明，研究区内面蚀侵蚀量最大，沟蚀次之，重力侵蚀最小，分别占总量的46.8%，35.1%和18.1%。

Using the model conclusion might be gotten in the studied watershed , that is , erosion amount by surface erosion is the greatest ( 46.8 % ), gully erosion the greater ( 35.1 % ) and gravity erosion Lhe least ( 18.1 % ) .
