With the rapid development of industrialization and urbanization as well as enhancement of geographic differentiation and diversity of man-earth areal system, functions and regional development orientations in metropolitan suburbs have shown an increasingly strong trend towards diversification. It is one of the keys to draw up the Rural Revitalization policy objectively to evaluate the multi-functional system and then sum up pattern of metropolitan suburbs. The multi-functional evaluation method of metropolitan suburbs was constructed. The multi-source spatial data, statistical data and survey data were used to evaluate the multi-functional values of the 89 towns in Shanghai. The results showed that: (1) There were significant differences in the development of multifunction among 89 towns in Shanghai. The order of mean values is listed as ecological environment function (0.7674) > economic development function (0.6054) > agricultural production function (0.5882) > life guarantee function (0.5238) > leisure culture function (0.2525). (2) The high value areas of the ecological environment were mainly distributed in Chongming Island, Western Qingpu and Southern Fengxian. The high value areas of agricultural production were mainly located in Southern Pudong, Fengxian, Jinshan, Southern Chongming and Qingpu. The high value areas of economic development was mainly located in the vicinity of central city. The low value areas of life security were mainly located in the towns close to the central city and the most remote towns. The high value area of leisure culture was mainly located in Songjiang, Qingpu and Jinshan, which are the most remote from the central city. (3) A total of 89 towns could be divided into 4 types: balanced, mixed, compound and dominant. Among the 8 subdivision patterns, only 10 towns like Pujiang town were multi-functional and presented a highly balanced development pattern, accounting for 11.24%. Thus, the final but main part of this paper envisions the innovative policies and practices in metropolitan suburbs including the diversified rural renewal, homestead regulation, and low efficiency industrial land reduction.
