Detailed Description

风蚀水蚀交错带侵蚀能量特征模型

 

(1)风蚀能量的计算模型:

式中,C为风蚀能,实际为单位体系的风蚀能,对于地表来说,则为单位面积上的侵蚀能;ρ为大气密度;Vi为月平均风速;Ei为月平均蒸发量;Pi为月平均降水量;Di为月天数。

(2)雨蚀能量的计算模型:

             R=Ped

式中,R为降水侵蚀量;e为单位雨量的动能;P为年汛期降水量的多年平均值;d为降雨历时。

(3)地形附加侵蚀能量Eg模型:

                        Eg=mgHS

式中,m为质量;g为重力加速度;H为地面切割深度;S为土壤侵蚀面积率。
