Comparative Studies on the Evolving Laws of River and Lake Pollution Crises

A comparative analysis on the river and lake pollution events is performed involving the causative factors and the destructive effects. And base on the investigation of the relevant major pollution cases of China in recent years, the corresponding effect resulting from the factors with the respective chronic and acute properties are addressed. Then the emergent public affairs deriving from the water pollution and the topology relationship of the crisis network are represented, and the propagation performance related to the individual crisis is explored and compared mutually. Furthermore, the countermeasures, associated with the current measures, are suggested to deal with the pollution problems and control the extending derived crises regarding to the lake and river respectively. Particularly, it is noticeable that keeping biological chain balance of the lake ecosystem is one of the most crucial factors in the lake pollution treatment, which has relatively small effect for the river.
