Description :
This paper, taking the Changchuan Watershed as a case study, on the basis of field investigation and by means of multiple objective programming and GIS approaches, discusses the interactions between land use, soil erosion and water consumption, in an attempt to better understand if an optimized land use structure with deliberately readjusted spatial pattern can effectively control soil erosion and rationally use water resources in the region, in order to eventually contribute to the soil and water conservation, land resource utilization, ecological conservation, and development of the region.
