摘要:本文通过九里区塌陷湿地水文条件及污染状况调查,对湿地水体的总氮、总磷、化学需氧量、叶绿素、透明度、溶解氧等指标进行了检测,根据检测指标,对湿地水体进行富营养化评价,然后从面源污染与点源污染两个方面分别预测了未来五年塌陷湿地限制因子总磷、总氮浓度,最后,根据水体富营养化评价和预测结果,给出湿地合理的富营养化防治措施。

Research on Forecast and Evaluation of Water Environmental Quality in Xuzhou
Abstract:the hydrology and pollution of the collapse wetland were investigated in this paper and the indicators of total nitrogen, total phosphorus, chemical oxygen demand, chlorophyll, Secchi depth and dissolved oxygen was tested. According the results, the eutrophication of the collapse wetlands was evaluated, then predicted the levels of TP and TN of the collapse wetlands from non-point source pollution and point source pollution, respectively. Finally, according the evaluation and prediction results of eutrophication, a reasonable eutrophication control measures of wetlands were put forward.
Keywords: Collapse wetlands Eutrophication Evaluation and predication
