| 摘 要： | 一、前言建立高效的农业生态系统必须从全面分析系统的结构、功能特点以及系统中各因子之间的相互关系着手,阐明影响系统功能的主要结构因子和条件因子,从而为增强系统功能拔出有效的调控途径与调控措施。农业生态系统是一个多层次、多组分、多变量的复合系统,可以从任一层次水平上开展研究,或乡、或村、或户。鉴于目前大多数农村仍以农户为生产单位,以分散经营为特色,故本研究从农户这一

| Abstract: | The index system for household ecosystem analysis is put forward according to the structuraland functional characteristics of household ecosystem.PCA analysis are made for 22 condi-tional and structural indices and 26 functional indices.Dominant factors reflecting systemstate and structure are input level and productive structure,and those reflecting systemfunction are total output value and other 6 indices.70 households are classified into 4 typesby means of system clustering.The effects of household ecosystem's condition and structureon its functions are analysed using partial correlational and multiple regression analysis.Development potentialities and policies for various types of household ecosystems are discu-ssed. |
