Taking Fengyang Town of Fenxi County, Jiangxi Province for example, this paper applied Arc GIS to analyze natural facors, social economy, and construction factors quantitatively by evaluating development and construction conditions of each village comprehensively from the perspective of urban-rural integration. Classifying the villages into 4 types, namely urban reform type, concentrated development type, controlled construction type and relocation type, this paper tried to guide the scattered rural settlements to the intensive development.展开更多

By analyzing three cases of industry layout planning of Shenzhen, in particular the evolution of planning thoughts and the implementation effect of the plans, this paper argues that an effective industry layout planning should focus on studying the spatial requirements of industries and creating the suitable physical environment for industrial development instead of directly arranging the layout of various industries. Moreover, the implementation of the latest planning policy in Shenzhen proves that the industry space policies issued by the local government should be problem-oriented and be aimed to solve the practical difficulties in the innovative development.展开更多
