农户生态系统定量分析和演替导向的研究

THE STUDY ON THE METHOD OF QUANTITATIVE ANALYSIS AND DECISION-MAKING IN FARMER'S HOUSEHOLD

文章研究了农户生态系统定量分析和演替导向方法,对线性规划方法有新的应用和认识,提出了制约强度、制约幅度、制约作用量的新概念,并首次用于对农户生态系统管理中的限制因素定量分析,从而指导农户生态系统的演替,并取得明显的实践效果。同时,对线性规划方法在农业生态系统分析中的进一步应用进行了讨论。

The methodology of quantitative analysis and decision-making in farmer's household was studied in this paper. The newly application of linear programming is also found. The new concepts of constraints'intension,constraints' range and constraints' degree are proposed and have been used first to analysis quantitatively constraint factors in farmer's household agro-ecosystem and then to make decision for farmer's household management. By means of this the direction for household agroecosystem succession has been guided and good practical results have been got too.The further application of linear programming in the analysis of agroecosystem is also discussed.
