随着沿海地区经济和人口的不断发展, 人类活动对海湾水质状况的影响日渐加剧。本文以大亚湾为研究对象, 以近20年的调查统计数据为基础, 综合运用变异系数评价、双变量相关性分析、主成分分析、线性回归分析等方法, 对影响大亚湾水质的人为压力要素和海域承压要素所包含的指标进行筛选; 将自身变动幅度较大且对大亚湾水质产生主要影响的指标识别为关键控制指标, 并通过承载力占比的计算对关键控制指标进行量化解析, 继而对指标产生的水质效应进行定量评价。结果表明, 人为压力要素中的围填海面积、生活污水排放量和工业废水排放量这3个指标的变异性大、主成分综合载荷数较高且与大亚湾海域的主要污染物溶解无机氮含量的年际变化有显著相关性, 是影响大亚湾水质的关键控制指标。对这3个指标进行承载力占比计算的结果显示, 围填海面积、生活污水排放量和工业废水排放量的承载力占比分别为6.19%、5.07%和17.51%, 其中工业废水排放的占比最高, 对海湾承载力的影响最大。以上研究显示, 人类活动是造成大亚湾水质恶化的主要原因, 为有效改善大亚湾的海洋环境质量、提高管理水平, 应从岸线整治修复和陆源排污(尤其是工业废水的排放)控制入手, 科学制定管理方案, 推动大亚湾地区的可持续发展。

With the rapid development of economy and population in coastal areas, the water quality of the main bays around the world has been affected by human activities which results in the deterioration of the ecological environment. Based on the survey and statistical data from 1995 to 2014 in the Daya Bay, Guangdong Province, China, coefficient of variation method, bivariate correlation analysis, principal component analysis and linear regression analysis were used to identify the key controlling indicators from the anthropogenic pressure indicators and coastal carrying indicators, which have significant impact on the water quality of the Daya Bay. The proportion of the carrying capacity of each important controlling factor was used to quantify the water quality effect. The results showed that the key controlling indicators contained three anthropogenic pressure indicators, including land reclamation, domestic sewage discharge and industrial wastewater discharge. The key controlling indicators had remarkable variation and greater loading values, and they were significantly correlated to the CDIN which was the main pollutant in the Daya Bay. The quantitative assessment results showed that the carrying capacity of key controlling indicators (land reclamation, domestic sewage discharge and industrial wastewater discharge) were 6.19%, 5.07% and 17.51%, respectively, of which the proportion of industrial wastewater discharge is the highest and has the greatest impact on the Daya Bay. Therefore, human activities were the main cause for the deterioration of water quality in the Daya Bay. These results illustrated that the control of land-based pollution and the regulation of the coastline should be implemented to promote the sustainable development of social economy around the Daya Bay.
