摘要

以土壤风蚀的随机理论为基础

建立了土壤风蚀的一类随机过程模型。并求出了在任意时刻任一类可风蚀物质的随机概率分布、数学期望 (平均风蚀量 )以及平均风蚀量的方差。与前人的研究相比

该模型不需要规定时间的长度

可以将影响风蚀的不同因素分为不同的类别

以便进行单一风蚀因子影响分析或通过求出各因子之间的联合概率密度分布而进行综合分析.

Abstract

Based on the stochastic theories of soil wind erosion

a stochastic model for soil wind erosion isfounded

and the stochastic probability distributions

expectations and variations for stun a kinds erodible soil particles at any time are calculated. Com-pared with the former researches

the model do not need to limit the length of the time

and classified the factors which influence the wind erosion as different kinds. And through those can analysis for single factor or through calculating the joint probability density distributions of those factors and analysis the relations-hips of those factors synthetically.
