1. As an application of the general dynamic model, we develop a biotic self-cleaning model that could manifest criticality resulting from change in biotic pollution absorption capacity. 以此为基础，构造了一个包含“S”形过程的生物自净模型，该模型可以刻画因生物的污染净化能力变化所引起的临界性。

5. The community succession series was sandy pioneer community stage→rhizome herb-grass community stage→sandy shrub community stage→sandy P. tabula 群落演替进程为沙地先锋植物群落阶段→根茎禾草杂类草群落阶段→沙地灌丛群落阶段→沙地油松林阶段。
