Study On Urban Construction Optimization In Nanjing Under Ecological Vision

The optimization of urban construction is an important part of the new type of urbanization.It aims to solve the ecological problems,improve the public quality of life,building a harmonious socialist society.It also plays a pivotal role.The research on urban construction optimization under the ecological perspective is not only an important practical content of the construction of socialist cities in China,but also an important topic for improving the new urbanization and urbanization theory in China.Based on the new era of urbanization and the construction of metropolitan center city,this paper aims to build a more natural and harmonious livable city on the theme of "optimization of urban construction under ecological vision".The text firstly introduces the background and practical significance of the research and the current research status at home and abroad.It also illustrates the content,method and innovation point of the research.This paper introduces the theory of ecological city construction closely related to this research,and introduces the new urbanization theory of Chinese characteristics based on the close combination of China's national conditions.This paper reviews the history of Nanjing construction process,discusses the spatial layout of Nanjing city construction,and makes clear the realistic background of Nanjing urban construction.This paper introduces the historical vicissitude of the ecological localization of Nanjing construction,expounds the overall cognition of Nanjing and expresses the ecological orientation of Nanjing city construction.Finally,it sums up the Nanjing urban construction the basic characteristics of the ecological location,including city community from competition exclusion to mutualism,urban capacity from the cities to megacities,the elements of the city never big shift towards megacities coordination to the coordinated development.In the process of construction in Nanjing,the ecological status of urban ecological appeared gradually.This article elaborated the Nanjing urban construction from five aspects of ecological status quo and the reasons,including urban congestion is difficult to ease,serious environmental damage,supporting uneven distribution of resources,cost of living differences,severe population stratification differentiation.At the same time,this paper introduces the reasons for the non-ecological status of urban construction in Nanjing,including the planning and implementation of scattered construction point,and the lack of ecological concern,heavy construction,light management,rely on land finance.This paper studies the overall environmental and social problems in the process of urbanization,as well as the unique or outstanding problems of Nanjing.Urban construction and development cannot separate from the experience and lessons learned from other cities at home and abroad.This paper first introduces the overseas examples of urban construction,including Hangzhou,Paris in France,Curitiba in Brazil,Seoul in Korea,Chiba in Japan and Zhuhai.This paper also summarizes the experiences of foreign urban construction optimization,it is concluded that are beneficial to the urban construction of nanjing and even the whole country the beneficial experience,including rational utilization of urban green space and landscape resources,protect the development of the old city,vigorously develop public transportation,insist on planning guide.This article also summarizes the lessons of the development of urban ecological space at home and abroad,the transition to commercial city Lijiang,excessive pursuit of complanation and low density in Los Angeles and mumbai,India,and the lack of ecological concern of Datong in Shanxi Province as an example.In the future,the construction of livable and more competitive city is inseparable from the theory of keeping pace with The Times.In order to solve the existing problems of social reality more effectively,we should adhere to the ecological concept to guide urban construction and development.We need to speed up the construction of sponge cities,public urban green Spaces,maximum protection of landscape resources,and the use of clean energy and waste recycling.We also need to systematically promote urban space construction,optimize public transportation network,repair urban sewage system,rationally conduct land development,and ensure the coordination of zoning and positioning.Cities are not independent existence,we should pay attention to the new construction with contact surrounding city,promote mutually beneficial symbiosis of city community,actively implement the new city infrastructure construction,satellite town functions,strengthen mutual aid and the surrounding city of resources,gradually break the hukou system restricted factors.The research on urban construction optimization in Nanjing is an important link of urbanization and ecological civilization construction.Based on the problems found in city construction and optimization of the two areas of constructing research system,combining with the development of urbanization in Nanjing reality,and problems have been found to solve the problem in the process of the theoretical construction of the urban construction.In the process of problem optimization,this paper focuses on explaining the problems brought by the urbanization process from the perspective of ecology,and proposes relevant optimization Suggestions.Through theoretical guidance practice,this paper hopes to help relevant departments to improve the scientific nature of construction decisions.
