By analyzing the amount, development level, type, structure, and space distribution of the institutional pension facility in main urban district of Xuzhou City, this paper has summed up the main problems. Combining the estimation on the number of the elders and pension bed, coordination and planning of institutional pension facility in the research zone are conducted from three aspects: distribution guidance, principle of locating and differentiation configuration, to promote the construction of pension agency and impel the development of pension business in Xuzhou City.展开更多

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
