Abstract It is very important to make known mechanization of land use space difference on the Loess Plateau,which is the key in improvement of man-land relationship.The method of quantitative ecology to analyze multi-variation relationship between land use change and its driver factors in Jinghe River Basin in middle of the Loess Plateau was borrowed.Land use pattern appears territorial difference in middle of the Loess Plateau and its main driving factors are slope,rainfall,population density,mechanization of work farm and river density.Slope is positive to forest land ratio and shrub land ratio,while negative to that of building land.Rainfall is positive to forest land ratio.Population density is positive to farm land ratio and that of building land ratio.Mechanization is negative to farm land ratio and that of shrub land ratio.The quantitative canonical load of these driver factors to change of land use pattern was given at last.
