Study On Regulation And Problems Of Urban Inland Rivers In Dongguan City

With the development of the country's urbanization,due to the large number of pollution sources and limited internal water sources,coupled with the weakening of the automatic purification capacity of the inner river,the environmental conditions of the inner river flow in the city have become worse and worse.The ecological environment of urban rivers is not only severely damaged,but also affects the health of residents living on both sides of the river.At present,although China pays enough attention to the management of urban river surges and has taken various measures and achieved certain results,there are also many problems.Due to the lack of the remediation plan and the imperfect management system of the urban river surge management system,the management of the urban river surge in our country has achieved little success for a long time.Therefore,we need to seek a more scientific and comprehensive remediation plan with the idea of sustainable development in the management of urban water environment.The management of urban river surges is not only directly related to the quality of urban water environment,but also to the health of urban people.Therefore,river surge regulation in urban environment has always been the core content of urban construction.In response to the slogan of national ecological civilization construction,Dongguan City formally promulgated a work plan for the comprehensive implementation of the river length system in Dongguan City in 2017,requiring the city's rivers and lakes to fully establish the river length system and build a three-level river length system in cities,towns,and villages.Organizational system.Achieve the overall goal of "Flowing river,Clear water,Dike,Coastal Green,beautiful scenery".Based on the current situation of river management in Dongguan city,combined with the experience of urban water environmental management,this paper uses the relevant theoretical basis of public management,and based on the many problems in Dongguan city river management,draws on the experience of inland management of advanced rivers abroad.It puts forward that the countermeasures for the remediation of rivers in Dongguan cities are to control pollution,strengthen the management of facilities and technologies,restore the natural nature of water bodies,and take the improvement of the ecological environment as the main line,and consider comprehensively from the three aspects of the regulatory body,the regulatory process,and the regulatory basis.Relying on the system of river length,an effective plan for rectifying the inner river surge in Dongguan City is put forward.This thesis consists of six parts: the first part of the introduction.The research background of this topic is introduced.This paper puts forward the research purpose and significance of this topic,and expounds the research methods and experience of domestic and foreign scholars on the regulation of inner rivers.The second part of the basic concepts and theoretical basis.This paper mainly expounds and explains the relevant concepts,including the inner river surge,the river length system,and the inner river surge rectification,as well as the theoretical basis used in this paper.The third part is the great significance of strengthening the improvement of the inner rivers in the city.This paper mainly discusses the purpose and significance of current river surge regulation in the city.The fourth part is the present situation of the existing problems of river surge remediation in Dongguan.This paper mainly introduces the overall effect of river surge remediation in Dongguan city,and takes the river surge basin in the center basin of Guayingzhouwei,Dongguan city as a case,and puts forward the problems existing in the process of rectification,and analyzes the reasons for them.The fifth part is the countermeasures to strengthen the rectification of the inner river in Dongguan.The corresponding measures and suggestions are put forward.The sixth part is the summary of the full text,and put forward the prospect of this study.
