摘要
以重述的热力学第二定律阐述生态系统即耗散结构，并以李亚普诺夫稳定涵义理解系统脱离平衡时的特性，得出越过生物熵直接解出生态系统的新思路。尝试沿此思路来构造生态系统的物理模型，为使热经济学再进而结合生态平衡探索途径。
By using the concept of Restated Second Law of Thermodynamics, It is approved that the ecosystem is just a dissipative structure which does not violate the restated second law,and if the ecosys,tem is understood as a state of Lyapounovs stability of equilibrium, a new approach is obtained for solving the exergy of ecosystem without determining the entropy of biomass which by now none can solve. By following such a new idea,a physical model of ecosytem is tried to be constructed, and therefore, a new way for combining thermoeconomics with a consideration of ecological equilibrium is able to be developed.
