Modeling the relationship of land use change and some geophysical indicators for the interlock area of farming and pasturing in China

This paper discusses land-use changes in the interlock area of farming and pasturing (IAFP)in northem China. It presents detailed analyses of land-use features in the IAFP, which are controlledby the macro geomorphic units and geophysical conditions-constraints or advantages. Additionally, itselects some indicators, according to the availability in acquiring and processing their quantitative data,to analyze the canonical correlations between the typical conversion of grassland and geophysicalconditions. The preliminary study indicates that the physical conditions are of great advantages to thedevelopment of grassland. There exists significant correlation between land use change and somegeophysical conditions.
