Abstract: Starting from the concept of rural complex,quantitatively evaluate the building capacity of the rural complex in township,and provide theoretical support for the comprehensive utilization of agricultural land in Gaochun District.Taking Gaochun District of Nanjing as an example, this study constructed a quantitative measurement system covering modern agriculture, leisure tourism and rural communities, and used GIS spatial analysis, TOPSIS and obstacle model to analyze the building capacity and impediments of rural complex,which we took the town as the study scale,on the basis of which to refine the development path of differentiation.The results showed that:(1)The spatial differences of building capacity were significant in modern agriculture, leisure tourism and rural communities.(2) The three dimensions of leisure tourism, rural communities and modern agriculture had different degrees and directions for the building capacity of rural complex.(3)The main barrier factors were different from each other, and the factors had complex control effects. (4)The research proposed corresponding construction paths for the land use of the eastern slow city ecological zone, the central and southern surrounding wet area, the western water township network area, and the central and northern center old city.
