在生态建模中的作用

阐明可以作生态系统污染物排放环境保护以及生态平衡的总指标，进而指出生态建模通用原理，即对于一切生物都有改变本身结构以至于组成来适应环境变化本领，其能承受环境施加影响的限度称为生态学缓冲能力，为了维持这种缓冲能力，一切生态系统都趋向于自身具有最大的值，叫做“趋最大化原理”，这是以作指标分析研究生态系统一条通用的原理。

The Role of Exergy in Ecosystem Modelling

It is expounded that the exergy can serve as a general criterion for ecosystem, pollutant emission, environmental protection and ecological equilibriem. Furthermore, a general principle for ecosystem modelling is pointed out,that all living beings have a capacity for changing their structure, even their composilion to suit the evironmental changes. The limitation for bearing the impact exerted by the environment is known as buffer capacity. In order to maintain such a capacity, all ecosystems tend to have the maximal exergy, that is called "The principle of exergy tending to maximum". That is a general principle for analyzing ecosystem when the exergy is used as the criterion.
