In accordance with the specific eco-environmental background and socioeconomic characteristics,a field experiment was conducted to deal with the characteristics of the agricultural ecosystem pattern and its operation status.By considering the abundant hill and mountain resources in the Yangtze River,the agricultural ecosystem pattern named FPH-PB was designed in unit of small watershed in order to adjust measures for local conditions.The FPH-PB pattern integrates the support-and-demand relation and operation mechanism and its applicability.Comparing to the traditional cropping pattern of CK and widely used pattern of pure pear orchard,the FPB-PH pattern provides higher economic and ecological benefits,especially in reducing soil loss.With the help of technologic exploitation and instruction from universities and academies,the FPH-PB pattern orients direct consumers and intermediary processing industries,provides experience of small watershed management and speedups the industrialization of agriculture in the Three Gorges Reservoir area.
