Achieving sustainable development through China’s national territory spatial planning requires comprehensive knowledge of all land characteristics. This paper introduces a land-type map of Jiangsu province (104 km2) in eastern China to provide such knowledge. The land-type map focuses on both physical geographic components (e.g. climate types, landforms, and soil types) and human-related components (e.g. land-use types and intensities). These components were represented by parameter layers and integrated with the help of the Geographic Information System (GIS) overlay function. A hierarchical land-type classification system was generated to provide land mapping units that represented certain degrees of geographic homogeneity and land-use potential. Trading off the relationship between resource protection and resource utilization, the space of Jiangsu was divided into seven land-use zones with different land-use policies based on the land-type map. The land-type map can thus be taken into consideration for land planning and management.
