摘要
通过对松辽流域风蚀图斑资料的收集,运用线性模型理论,对该地区土壤风蚀规律进行了研究,获得了下垫面备因素与风蚀量之间的相互关系。又通过计算机进行统计分析,找出了影响风蚀量的主导因子是土地利用类型和植被覆盖度。并可利用设计的数学方程,对该地区不同立地条件下的风蚀量进行预测。
Wind erosion mp delinecation data in Songhua and Liaohe river watershed are collect-ed,and wind erosion laws are studied with linear model theory.The results show that the princi-pal factors to effect wind ersion are land use type and vegetation coverage。Wind erosion in everykind of sites in this watershed is predicted with the linear models established.
