Beginning with the problem of interlaced region between farming and herding, the boundary line of the interlaced region is calculated based on grid with 10km grid ; then the relation among land use of the region, soil erosion and erosion region is analyzed ; based on factor classification, no useful factors were neglected and stepwise regression method was used to analysis the drive of land use change ; fractal method was applied to analysis the degradation of land - use and relation among land use, soil erosion and wind - water erosion zone ; environmental variances are introduced to establish characteristic index of land use change and analysis the effect of land use change on soil erosion
從農牧交錯帶的實質問題入手,基於10公里網格,計算農牧交錯帶的界限;在此基礎上分析農牧交錯帶的土地利用、土壤侵蝕及與風水侵蝕帶的關系;在因子分層的基礎上,剔除不需要因素,採用逐步回歸的方法,進行土地利用變化驅動力分析;運用分形方法分析土地利用的退化,並分析土地利用與土壤侵蝕的關系,引入環境變量,建立土地利用變化特徵指數,分析土地利用變化對土壤侵蝕的影響。
