草地农业生态系统的自组织特性

根据自组织理论探讨了草地农业生态系统的6个自组织特性，即草地农业生态系统的结构性、有序性、非线性、开放性、非平衡性和涨落性。认为，草地农业生态系统是一个自组织系统；它只有不断地与外界进行物质、能量和信息的交换及系统内部的协同效应，才能产生结构和功能的有序状态；对草地农业生态系统的调控，必须抓住物质和能量输入的控制，特别是要控制系统内部生态的、经济的、技术的因素以及生产劳动因素之是的协同效应。

The self-organizational characteristics of grassland-agriculture ecosystem

The self organizational principles were analysed , based on self organizational theory , and six self organizational characteristics of grassland agriculture ecosystem were discussed, i.e. structural characteristic, ordered characteristic, non linear characteristic, open characteristic, non balancing characteristic and fluctuating characteristic. The conclusion is that the grassland agriculture ecosystem is a self organizational system; the grassland agriculture ecosystem can be brought about order of its structure and function only if it exchanges matter, energy and information with environment and cooperative effect of the inner system factors; and the grassland agriculture ecosystem can be adjusted only if input of matter and energy, especially cooperative effect of ecological factor, economic factor and technical factor of the inner system and anthropogenic factor intended to act on the system are controlled.
