六、农业生态系统的机能分析 生态系统的机能主要指其对物质、能量的转化特点和转化效率。它是生态系统的最重要特征,是研究生态系统生产力的中心,是调节、控制和管理生态系统的重要方向。从生产观点出发,研究农业生态系统往往最关注的是整个系统的生产力,不同于一般农业生产讲的只是作物产量。在物质能量转化循环的系统上,生产力取决于对物质能量一系列的转化效率。
Sixth, the functional analysis of agro-ecosystems The function of the ecosystem mainly refers to its conversion of material and energy characteristics and conversion efficiency. It is the most important feature of the ecosystem, the center of ecosystem productivity, and the important direction of regulating, controlling and managing the ecosystem. From a production point of view, the study of agricultural ecosystems is often the most concerned about the productivity of the entire system, unlike the general agricultural production is talking about the production of crops. In the system of material energy conversion cycles, productivity depends on a series of conversion efficiencies to material energy.
