对生物自净模型动态演化过程的数值模拟发现，其临界特征在污染治理中有重要意义，如果污染治理时刻晚于某个临界值，环境系统的演化轨迹将突然发生变化。

The simulation of the biotic self-cleaning model shows that the critical characteristics have great significance in the pollution abatement , that is , the evolving locus will dramatically alter if pollution abatement moment comes later than some critical moment .

通过对水中生态食物链的分析，提出了通过投加以光合细菌为主的复合细菌群来强化湖泊水体生物自净能力，改善湖泊水体水质的方法。

Through analyzing the ecological food chain in water , the method adding compound bacterial groups in which photosynthetic bacteria were in the majority was suggested to intensify self purification ability of the lake and to better water qualities of the lake .

并对建立和保持“生物&生态水体自净系统”过程中需避免和解决的问题提出独特的见解。

Opinion on how to avoid and solve problems during the process of constructing and keeping the system was proposed .
