Abstract:In this paper stability and sustainability of food production and agricultural output value were used to assess the general holostic production performances,and homogenity or diversity was used to express the overall agricultural development of the compound agro-ecosystem in Fuma village,which is located in the subtropical hilly region.The results from analysis of the input-output of energy,N,P,K and funds in each subecosystem showed that the overall flux of those factors and system openess were all increased in the recent ten years,and the utilization efficiency for solar radiation was increased,energy input-output ratio was decreased in cropland sub-ecosystem.For animal husbandary sub-ecosystem,transfer rates were increased significantly.The population bearing capacity of land was also increased from 13.8 persons/ha in 1980 to 15.5 persons/ha in 1989 based on the rapidly developing animal husbandary.By calculation it was suggested that the food production in this region could support double its present population.
