Abstract：With the enhancement of geographic differentiation and diversity of man-land areal system in the process of long-term economic growth and large-scale urbanization, rural functions show a clear trend of increasing diversification. For the differences of resource endowment, location condition, stage of economic development and developing strategic orientation, rural functions in various regions have significantly spatial heterogeneity and temporal variability. Based on the definition of dominant function as well as the building of multifunctionality evaluation models, this paper evaluated the functions of economic development, grain production and eco-conservation of rural area along the Bohai Rim in 2000 and 2008. Function ecostate in 2008 and function ecorole between 2000 and 2008 were selected as indexes, based on SOFM network model, the study area was finally divided into 3 regions of rural dominant function and 13 sub-regions, and then characteristics of each functional areas and development orientations were analyzed. With slow economic development and weak social security function, grain-oriented functional areas are mainly distributed in plain area, and their development orientation is to build core area of food production and agricultural advantages of industrial clusters, to improve food production capacity. Eco-conservation functional areas are concentrated in mountain areas and hill areas, in which eco-priority land use strategies and ecological compensation should receive special focus.
