According to the interpretation results of composite TM images of the Yanhe River Catchment and Ansai County in 1990 and 2000, and based on the field investigation on the eco-construction activities from 2000 to 2006 in this area, the land use/cover change and its driving factors in the Yanhe River Catchment and Ansai County were analyzed at both catchment and county scales. The driving force models of cultivated land area change were established at both catchment and county scales. Based on the relationship among the common driving factors at different scales, a scale conversion method for cultivated land changes at different scales was established. The results showed that, for land use/cover change models at different scales, they could be converted based on the quantitative relationship of key driving factors, no matter how complicated the models were. The study results would put new insights into the scale conversion research of land use/cover change.

Key words: driving force models, land use/cover change, scale conversion, Yanhe River Catchment
