紧水滩水库龙泉段水体营养化状况的调查分析

Eutrophication Investigation and Analysis of Longquan Department of Jinshuitan Reservoir

通过对紧水滩水库龙泉段水质监测结果的综合评价分析,基本掌握了紧水滩水库水体的营养化状况及其变化情况,即水库水质已有好转趋势,处于中营养水平;对叶绿素a与环境因子进行了相关分析,叶绿素a与pH、溶解氧、总氮、总磷和高锰酸盐指数呈现显著的正相关关系,与水温呈偏相关,与透明度呈显著负相关关系。

According to the comprehensive evaluation analysis of water quality in Longquan segment,Jinshuitan Reservoir,we have grasped the change and the nutrition of water basically.The water quality of the reservoir has been improved in a good trend –in the mesotrophic level;we also analyze the chlorophyll A and environmental factors.It concludes that chlorophyll A is to pH,dissolved oxygen,total nitrogen,total phosphorus and potassium permanganate index shows a significant positive correlation;to water temperature was a partial correlation;while to the transparency is a significant negative correlation.
