| 摘 要： | 现代生态系统是以人类为中心的自然生态系统和社会系统的耦合系统。从热力学观点看,生态系统中生物与环境的物质、能量流动必然引起系统熵的变化。本文从非平衡热力学角度讨论生态系统的热力学本质;生态系统的信息熵;生态系统类比;生态平衡。

| Abstract: | The modern ecosystem which centres on mankind and biology is a comprehensive combination of natual ecosystem and social system. It is a system of living motion which results from the exchange of matter and energy between the system and its surroundings. The second law of thermodynamics studies essentially the exchange of matter and energy between ecosystem and its surroundings ;This exchange is the ultimate motion in ecosystem. Thus,in the view of non-equilibrium thermodynamics, the exchange of matter and energg between ecosystem and its surroundings will inevitably cause entropy changes of ecosystem. This paper studied some problems of the ecosystem with non-equilibrium thermodynamics. |
