摘要
运用系统分析法,对严家湾村农业生态系统的能、物流进行了分析、诊断与评价。通过调控系统能、物流结构以及实施农业生态工程技术,使系统趋于功能最佳、结构最优的良性生态农业模式。
The cnergy flow and the nutrient cycle of agroecosystem in Yanjiawan
Village were analysed and evaluated by system aticlly analytic method.
After that,several agroecological engineering techniques regulating the
structure and functions of the agroecosystem were taken into operation.
Finally,the ecological agrocultural model with the characteristics of ex-
cellent functions and optimal structure in this area were set up.
