Comprehensive Evaluation and Differentiation Characteristics of Eutrophication in River Waters of Guangdong Province:Based on Game Theory Combined Empowerment Method and VIKOR Model
摘要
Abstract
Guangdong Province is one of the most economically developed provinces in China and has a high GDP among the country's provincial administrative regions.However,as the province's economy continues to grow and urbanization accelerates,river water ecology problems have arisen to a certain extent.Conducting an in-depth investigation of these problems is profoundly significant for the sustainable and healthy development of Guangdong Province.In this study,we focused on 94 river monitoring sections in 21 prefectural-level cities in Guangdong Province.We selected seven indicators to assess the status of eutrophication of the water bodies:total nitrogen,total phosphorus,dissolved oxygen,ammonia nitrogen,conductivity,turbidity,and permanganate index.Combining the empowerment method and the VIKOR model,we comprehensively evaluated the eutrophication levels and explored the management measures and principles for different degrees of eutrophication.The study found that 1)the overall water quality of river sections in Guangdong Province is good,with most sections being free of eutrophication,but certain areas exhibit varying degrees of eutrophication,including extremely heavy,heavy,moderate,and mild eutrophication.Different eutrophication conditions require specific management principles and measures to improve the efficiency of eutrophication management of river water bodies.2)Among the monitored river sections,Chaozhou,Maoming,Shaoguan,Qingyuan,Heyuan,Meizhou,Foshan,Zhongshan,and Zhaoqing did not show any signs of eutrophication.3)There is a clear spatial clustering effect of eutrophication in Guangdong Province,with more severe cases found in the southeastern coastal region.The eutrophication of water bodies in the Pearl River Delta(PRD)and the eastern part of Guangdong Province is particularly severe,followed by the western part of the Province.The northern part of Guangdong Province experiences the least severe eutrophication,indicating an overall spatial evolution of eutrophication from the southeast coast to the inland northwest.Water resources protection in Guangdong Province plays a significant role in regional sustainable development.It is crucial for all regions to actively respond to the call of the 20th CPC National Congress,embrace the concept of ecological civilization development,and effectively promote the governance of water environment.This will establish a solid foundation for the coordinated development of the regional economy,society,and ecological environment.关键词
