摘要
近年来海湾生境退化现象较为严重,造成这种现象的主要原因是人类活动和海岸侵蚀,其中,海洋开发活动、海上污染和陆源污染都会影响海湾水质。当海湾水质受到污染时会造成严重的生态污染,破坏了生态平衡。为了提高海湾水质,恢复海湾生态功能,提出区域海湾水质污染检测及生态危害研究。将山东省日照市作为研究区域,检测区域海湾内总磷、总氮等营养盐指标的含量分布及变化情况,更准确地了解海湾的污染状况;采用营养状况指数法分析上述营养盐指标造成的生态危害;结合潜在风险指数法评价重金属元素对海湾水质造成的生态危害,为后续的水质治理提供了有力的数据参考。根据此次研究结果,有助于为相关区域海湾的水质改善和生态恢复提供有效支持。
In recent years,the degradation of habitats in bays has been quite severe,mainly due to human activities and coastal erosion.Among them,marine development activities,marine pollution,and land-based pollution can all affect the water quality of bays.When the water quality in the bay is polluted,it can cause serious ecological pollution and disrupt the ecological balance.In order to improve the water quality of the bay and restore its ecological function,regional bay water pollution detection and ecological hazard research are proposed.Taking Rizhao City of Shandong Province as the research area,the distribution and changes of nutrient indicators such as total phosphorus and total nitrogen in the bay were tested to gain a more accurate understanding of the pollution situation in the bay.The study uses the nutritional status index method to analyze the ecological hazards caused by the above nutrient indicators.It combines the potential risk index method to evaluate the ecological hazards caused by heavy metal elements on bay water quality provides strong data reference for subsequent water quality control.The results will contribute to providing effective support for the improvement of water quality and ecological restoration of the relevant bay areas.
