围填海工程对钓梁附近海域水质的影响

Effect of Reclamation on Water Quality in the Sea Area near Diaoliang

为了解围填海工程对海水水质的影响,于2019年3月对钓梁附近海域的水质采样调查,与2013年3月的结果进行比较分析,结果显示:2013年和2019年的悬浮物相差显著,2019年是2013年的1.6倍,说明围填海工程引起水体中悬浮物显著增加,应合理进行悬浮物跟踪监测。活性磷酸盐、无机氮的含量仍旧劣于第四类海水水质标准,说明氮、磷含量普遍较高导致的海水富营养化依然严重,近岸海域水体富营养化目前已成为我国海洋环境污染比较突出的问题。

In order to understand the impact of reclamation on the quality of sea water, the water quality sampling survey in the area near Diaoliang was conducted in March 2019 and the results were compared with those in March 2013. The results showed that there was a significant difference in suspended matter between 2013 and 2019, which was 1.6 times higher than that in 2013. This indicated that the suspended matter in the water caused by reclamation increased significantly. Suspended matter tracking monitoring should be carried out reasonably. The content of active phosphate and inorganic nitrogen was still inferior to the fourth kind of seawater quality standard, which indicated that the eutrophication of seawater caused by the high content of nitrogen and phosphorus was still serious. The eutrophication of coastal waters has become a prominent problem of marine environmental pollution.
