Optimal Design Research Of Urban Green Space System Of Urban Area In Jiangmen Based On Sustainable Development

From the perspective of sustainable development,this paper takes Jiangmen city green space system optimization,in-depth analysis of its initial problem,as a ground point.By fully expressing the existing potential of green land,the city could be maximized its green ecological,social and economic benefits,and be realized the stable,healthy and sustainable development.In order to provide the theoretical basis for the city green space construction,this paper suggests a study for the foundation of the sustainable development in Jiangmen city green space system.First of all,the concept of sustainable development is analyzed,and the three basic concepts of sustainable development of urban green space,sustainable urban green space and urban green space system are defined.Through literature and reference,green space system development histories of both domestic and foreign city green space have been sort out.Several major theory formation process,development stage in the history have been cleared,leading to a trend that the sustainable development of city green space system is inevitable to achieve sustained and stable increase of green space.Secondly,from statistics the development of urban green space and the impact of the external region of Jiangmen urban green space,this paper constructs the basic frame of urban green space sustainability evaluation.Analysis of the basic situation;the evolution of combing the city space;research on city distribution,and analysis of kinds of green space,construction quality and quantity of green vegetation,the influence of natural geographical conditions,social economic conditions,and the circumstance of the city of city green space development have been analyzed.Thus provides a practical support for sustainable development for the optimization of Urban Greenland in this city.In addition,combing the sustainability of city green space,the mutual relationship between city green sustainability and sustainable development of city green space system leads to a consumption of the foundation for the sustainable city green space.Focusing on sustainable city ecosystem protection and sustainable way,the city green space optimization design of two aspects of sustainable development among them has been highly realized.The sustainability of city green space optimization design is a vital content in this paper,including a comprehensive planning,design and implementation of greening classification in three aspects,from the macro to micro planning practice to put forward the main optimization measures.Consequently,the sustainability of the optimized design method for guiding the sustainable development of Jiangmen city green space system were discussed.Concluding the ecological,social and economic benefits of the comprehensive planning regulation,the structure of green space system has been optimized.Problems of green space have been suggested to solve by a classification design optimization measures of various types of green space.Setting plant communities and future development target as a premise,a list of key species list,main species,and lay the foundation for long-term stability and development of green land have been developed.Through the Optimization Practice of the green space system in the main city of Jiangmen,this paper provides reference for the sustainable development of the Pearl River Delta urban green space system,and realizes the combination between concept and practice.
