扎龙河滨湿地水体营养化污染特征及水环境恢复对策

The characteristics of water eutrophication in Zhalong wetlands and strategy of environmental recovery

对扎龙湿地水体富营养化污染状况进行调查,指出沼泽湿地、湖泊湿地TN、TP、BOD5等多项水质指标都已严重超标;阐明了营养物年季变化特征;总结了扎龙湿地水体富营养化发展趋势;提出了保障湿地供水、生态工程恢复及控制流域地表水污染的多项管理策略。

In this paper, the author analyses the status of water eutrophication in Zhalong wetlands, and points out that the majority of water quality indexes, such as TN, TP and BOD5, have gone beyond the water quality standards seriously. Meanwhile, the author elucidates the characteristics of nutrition, then summarizes the eutrophication trend of Zhalong wetlands. Aiming at ameliorating the environment, some suggestions are brought forward, such as ensuring water supply, restoring ecology, and controlling surfacial water pollutants, and so on.
