摘要
农业生态系统结构的总体设计是农业生产发展的客观要求,同时,也是保证农村经济不断增长和农村生态系统良性循环的一个非常重要问题。农业生态系统边界范围较大,具有多层次、多因素、多目标、多途径等复杂性,要想深刻剖析农业生态系统结构和功能的关系,必须用系统工程的观点和方法对农业生态系统的结构进行控制和管理。
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”.
