葫芦岛市近岸海域功能区水质分析及对策建议

Analysis on Water Quality of Environmental Function Zone in the Coastal Seas of Huludao City

随着沿海经济的迅猛发展,近岸海域污染日益严重,成为影响海洋生态文明建设的主要问题之一。本文采用单指标评价法、综合污染指数法等方法对葫芦岛市近岸海域环境功能区水质达标状况、水环境质量综合状况进行了评价与分析。结果表明,2016年葫芦岛市近海环境功能区水质良好。同时本文提出以下对策建议:我国近岸海域污染防治应加强陆海统筹,切实削减氮磷入海总量;严格控制填海工程,坚决遏制滨海湿地丧失的势头;加强海洋生态环境监测,为我国近岸海域的可持续发展提供保障。

With the rapid development of coastal economy,the pollution of coastal waters has become more and more serious,which has become one of the main problems affecting the construction of marine ecological civilization. In this paper,a single index evaluation method and a comprehensive pollution index method are used to evaluate and analyze the water quality standard and the water quality of the coastal environmental functional zone in Huludao City. The results show that the quality of the offshore environmental functional zone in Huludao City in 2016 is good,and the compliance rate is 100%; The comprehensive pollution index of 12 stations in the coastal waters of Huludao City is between 1. 68 and 5. 19,according to the criteria for the classification of sea water quality. The pollution level of the sea area is located in clean and light pollution,and the water quality is good. At the same time,the following countermeasures are put forward： China＇s coastal pollution prevention and control should strengthen the overall planning of land and sea,and effectively reduce the total amount of nitrogen phosphorus into the sea; Strictly control reclamation projects and resolutely curb the loss of coastal wetlands;Strengthen the monitoring of marine ecological environment to provide the guarantee for the sustainable development of China＇s inshore sea area.
