漳泽水库底泥氮磷污染与表层水营养化关系分析

Analysis on the relationship between nitrogen and phosphorus pollution in sediments of Zhangze Reservoir and surface water nutrition

水库富营养化和底泥是造成水库水质污染的主要原因,本文对2017年10月至2018年9月期间漳泽水库库前、库中、库尾不同监测点的表层水和底泥总磷、总氮的监测结果特征进行分析,结果表明:水库富营养化程度随时间和空间变化明显,对应监测点的底泥中总磷含量随时间和空间变化均明显,总氮随时间变化不明显,随空间变化从库前至库尾整个监测期呈显著下降趋势,底泥与其对应的表层水氮磷含量无直接相关关系。本文研究成果为解决水库富营养化治理提供了依据。

Reservoir eutrophication and sediment are the main causes of reservoir water quality pollution.This paper analyzes the monitoring results of surface water,sediment total phosphorus and total nitrogen at different monitoring points of Zhangze Reservoir from October in 2017 to September in 2018.The results show that the eutrophication degree of reservoir changes obviously with time and space,while the sediment total phosphorus content at corresponding monitoring points changes obviously with time and space,while total nitrogen does not change obviously with time,and shows a significant downward trend with space change from front to tail.The research results in this paper provide a basis for solving the problem of reservoir eutrophication control.
