It applies the basis toestablish a sound development planning. In this paper, by applying multi-dimension niche concept, an eco-logical niche suitability (ENS) model was developed. The ENS model, combined with geographical informa-tion system (GIS) and spatial simulation, was used to analyze regional resources and environmental features ,and identify the suitability of regional resource and environment to regional development. An application ofthe ENS model in Taojiang agricultural land use planning is presented.展开更多
