秦皇島海域陸源污染調(diào)查及其控制對策研究
[Abstract]:Human beings must live and develop in harmony with nature. In modern civilization, ecological civilization is an indispensable and important part, and since human beings entered the era of industrial economy, land-based pollution has been accompanied by the shadow, its harmfulness is increasing day by day. Especially for cities such as Qinhuangdao, which depend on the sea and develop, land-based pollution undoubtedly brings great constraints to its economic development. Based on the analysis of the pollution status of the main rivers entering the sea in Qinhuangdao Sea area, this paper analyzes the sources of land-based pollutants in Qinhuangdao Sea area, and puts forward some reasonable control measures from three aspects: legislation, concrete measures and safeguard measures. The main conclusions are as follows: (1) through the sampling and analysis of several points in the coastal waters of Qinhuangdao City, the area of clean sea area is decreasing year by year, the eutrophication phenomenon is becoming more and more serious, and blue algae erupts frequently. (2) the main pollutants in Qinhuangdao seawater are inorganic nitrogen, phosphate, oil and so on. The sediment in the coastal area is still good, but the residual level of pollutants in shellfish in the local sea area is on the high side, and the total amount of pollutants carried into the sea by the river is still high. The marine ecosystem of coastal waters is in a sub-healthy state. (3) the main rivers in Qinhuangdao City are Yinma River, Yanghe River, Tang River and Dai River. Through the analysis of the data, it is concluded that the pollution of Yinma River and Yanghe River is the most serious. From the distribution of pollution sources industry, it is mainly concentrated in the black metal mining industry, agricultural and non-staple food processing industry and paper industry. Therefore, it is particularly important to strengthen the comprehensive regulation of these industries. (4) through the analysis of the present situation of land-based pollution, this paper puts forward some concrete measures, including perfecting the legal laws and regulations for the prevention and control of environmental land-based pollution, establishing a dynamic monitoring and forecasting system, establishing a regional coordinated management mechanism in coastal waters, raising citizens' awareness of marine environmental protection, establishing a long-term mechanism for the development of low-carbon economy, strengthening the social responsibility of agricultural enterprises, and promoting the reform of key areas. To realize ecological restoration, to establish ecosystem compensation mechanism and to construct comprehensive environmental improvement guarantee mechanism in Qinhuangdao coastal waters. By studying the influence of land-based pollution on Qinhuangdao and its surrounding sea areas, we can help us to further understand the existing land-based pollution, make people have a fuller understanding of land-based pollution, and analyze its seriousness and harmfulness to Qinhuangdao's economic development. Based on the present situation of land-based pollution, this paper puts forward reasonable countermeasures and suggestions, and puts forward orderly optimization suggestions from the enterprise level and the government level, so as to contribute to the development of Qinhuangdao's surrounding economy and realize the sustainability of Qinhuangdao and its surrounding areas.
