摘要: 根据2012—2016年大鹏湾近岸海域的监测资料,采用单因子污染指数法和有机污染指数法对海域海水水质状况进行评价;采用富营养化指数和潜在性富营养化指数对海域富营养化水平进行分析,并探讨其与环境因子盐度的相关性。结果表明:2012—2016年,大鹏湾近岸海域水质状况良好,满足GB 3097—1997《海水水质标准》中第二类海水水质标准,水质年际变化呈波动状态,无明显规律,空间分布上仅沙头角湾受到明显污染;富营养化水平基本表现为低营养,年际变化呈上升趋势,空间分布上仅沙头角湾和南澳湾分别呈现富营养和高富营养状态;潜在性富营养化主要集中在Ⅰ级(贫营养);大鹏湾近岸海域富营养化指数与盐度呈负相关,表明海域受河口冲淡水和陆源带来的低盐、高浓度的污染物影响较大。Abstract: Based on the monitoring data in the coastal area of Dapeng Bay in 2012-2016, the water quality of survey region was evaluated by using methods of single factor index and the organic pollution index. Furthermore, the eutrophication index and potential eutrophication index were applied to assess the eutrophication level, and the correlations between eutrophication level and environmental factors (salinity) also investigated. The results suggested that the water quality in the whole study area was generally good in 2012-2016, meeting Class Ⅱ seawater quality standards in Sea Water Quality Standard (GB 3097-1997), and the interannual changes were fluctuating without obvious rules. In the spatial distribution, only the Sha Tau Kok area was significantly polluted. The results of eutrophication level basically showed low-nutrient, and the interannual changes showed an upward trend. In the spatial distribution, only the Sha Tau Kok and Nan’ao Bay showed eutrophic and high eutrophic states, respectively. The potential eutrophication was mainly concentrated in grade Ⅰ (poor-nutrition). The correlation analysis showed that the eutrophication index was negatively correlated with salinity, suggesting that the surveyed sea area was greatly affected by low-salinity and high-concentration pollutants from estuarine flushing water and land-based pollution.
