本文试图对41个水生生态系统稳态模型的成熟度进行排序。成熟度是用Odum的生态系统成熟度的几个属性来量化的。它表明，它是可能的，这样的排名，排名似乎证实了我们的直觉感知生态系统的成熟度。该排名与基于各种生态系统目标函数的排名进行比较。成熟度排名显示出与相对优势的强负相关性，因此与系统开销的强正相关性，这是生态系统稳定性的一个可能的度量。分析表明，另一个目标函数，火用，这里计算的主要是系统生物量的函数，它可能是适当的重新考虑火用估计的计算方面。最重要的是，这些分析指出了利用生态系统模型的比较作为加强我们对生态系统特征，特别是可持续性的理解的工具的可行性。
An attempt is made to rank 41 steady-state models of aquatic ecosystems on the basis of their maturity. Maturity is quantified using several of Odum's attributes of ecosystem maturity. It is shown that it is possible to make such a ranking, and that the ranking seems to confirm our intuitive perception of ecosystem maturity. The ranking is compared to rankings based on various ecosystem goal functions. The maturity ranking shows a strong negative correlation with relative ascendency, and thus a strong positive correlation with system overhead, a possible measure of ecosystem stability. The analyses suggest that another goal function, exergy, as calculated here is mainly a function of system biomass, and that it might be appropriate to reconsider the computational aspect of exergy estimation. Most importantly the analyses point to the feasibility of using comparisons of ecosystem models as a tool for enhancing our understanding of ecosystem characteristics, notably sustainability.
