摘要

摘要: 为探究南湖水体浑浊的原因,通过2018—2019年现场调查,分析了南湖水体中悬浮物时空分布特征、组成、变化规律,并探讨了悬浮物的影响因素及其对水环境的效应。结果表明:南湖水体中总悬浮物(TSS)浓度为29.20~75.20 mg/L,平均值为38.95 mg/L,显著高于国内部分湖泊,且TSS以无机悬浮物(ISS)为主,占比为55.42%~79.25%,平均值高达66.80%;南湖水体中悬浮物的中值粒径以0~10 μm的细小颗粒物为主,占比为45.24%~83.73%,平均值为58.94%,显著高于周边水体;相关性分析表明,南湖水体中TSS浓度与总氮(TN)、总磷(TP)浓度呈显著正相关,说明悬浮物作为营养盐的载体,对南湖水质影响较大。

Abstract: In order to explore the cause of the turbidity of Nanhu Lake, the spatial and temporal distribution characteristics, composition and variation rules of suspended solids in Nanhu Lake were analyzed according to the detailed field investigation in 2018-2019, and the influencing factors of suspended solids and their effects on water environment were discussed. The results showed that the total suspended solids (TSS) content in the water of Nanhu Lake was obviously higher than those of some other lakes in China, ranging from 29.20 to 75.20 mg/L, with the mean value of 38.95 mg/L, and inorganic suspension was mainly in the water, the proportion of which ranged from 55.42% to 79.25%, with the mean value of 66.80%. At the same time, the median particle size of suspended solids was mainly small particles of 0-10 μm, and the proportion was 45.24%-83.73%, with the mean value 58.94%, which was significantly higher than those of the surrounding waters. Correlation analysis showed that the concentration of TSS in the water was significantly positively correlated with total nitrogen and total phosphorus concentrations, indicating that suspended matter, as a carrier of nutrient salts, had a greater impact on the water quality of Nanhu Lake.
