| 摘 要： | 以典型城市河流深圳河流域及新洲河流域为主要研究区域,分析了2017~2019年河流水质时空变化特征,借助对数型幂函数普适指数公式对流域的富营养化状态进行了综合评价。结果表明:深圳河及新洲河流域水体中CODCr、NH+4-N和TP浓度在不同水期,即丰、平、枯之间无显著差异,但在年际间具有显著性差异,浓度呈现降低趋势。深圳河流域CODCr、NH+4-N和TP浓度在丰水期空间变化幅度大,在平、枯水期空间变化幅度小。新洲河流域CODCr、NH+4-N和TP浓度在不同水期空间分布基本保持一致,流域水质从上游到下游逐渐恶化。深圳河流域的富营养化程度高于新洲河流域,且富营养化程度有逐渐减弱的趋势。

| Abstract: | Taking the Shenzhen River Basin and Xinzhou River Basin of typical urban rivers as the main research areas,the characteristics of temporal and spatial changes in river water quality from 2017 to 2019 are analyzed.With the help of logarithmic power function universal index formula,the eutrophication status of the basin is comprehensively evaluated.The results show that there are no significant differences in concentrations of CODCr,and TP during the different seasons in basins.However,the concentration shows significant decrease between the years.Water quality between the basins shows different spatial patterns.In Shenzhen River Basin,spatial variation in wet seasons was larger than in normal and dry seasons.The spatial distribution of CODCr,and TP concentrations in the Xinzhou River is Basin remains basically the same in different water periods,and the water quality of the basin gradually deteriorats from upstream to downstream.Eutrophication of Shenzhen River Basin is higher than Xinzhou River Basin,and the degree of eutrophication tends to gradually weaken. |
