Research on the Overall Structural Designing of Agroeoosystem in Jianping County

Abstract

Abstract: Simulation research has been taken out on the structure of agroecosystem in Jianping countyby methods of environmental differentiation,system analysis and system dynamics accordingto the existing structures of agroecosystem in the county.Evaluated comprehensively to thesimulation results of three kinds of experimental policies,th “agriculture-forestry-livestockfarming type” design appears to be better at the present time.After the funds,technologyand management level reach to a definite grade,it is urged to progress for the “comprehensivetype” and “industrial type”.

Key words: Black soil, Soil fertility, Comprehensive evaluation, GIS
