Abstract

The land use type is a pivotal factor affecting land productivity in loess hilly region.Using the land productivity model based on erosion,supported by geographic information system(GIS),the paper researched the relation between different land use types and land productivity of hilly loess region.The result showed,to a majority of crops,land productivity of different land use types has a law,namely,bottomland >terrace >slope land>gully wall.In order to research the mechanism further,the paper discussed adaptability index and productivity index of different kinds of crop for different land use types,which embodied the same trends.
