Green Space Planning Of Hilly City Based On Ecosystem Services

Rapid urbanization has brought serious ecological and environmental problems.Slowing down the trend of environmental degradation has become an important task of the global community,the contradiction between the land and the hilly city is an unprecedented challenge.Green space to provide a variety of ecosystem services,its importance has become increasingly prominent,as a remediation of ecological and environmental problems.Over the past two decades,the ecosystem approach has been studied and promoted as a tool to address climate change and protect the natural environment.Facing the growing environmental risk,I believe that the ecological system should be embedded in the hilly city green space planning theory and practice to optimize the planning and technical methods for the hilly city of regional green space planning to make a useful exploration to promote the hilly city sustainable development.The main contents of the paper include the following five parts:The first part mainly introduces the research background of green space planning in hilly city,the problems in green space construction and its causes,research significance,content,method and frame.The second part has carried on the related basic theory research at home and abroad.This paper mainly discusses the concept of hilly city,green space and ecosystem service,the planning paradigm,theoretical basis,development course and trend of ecosystem cognition and the classification of ecosystem services,its own characteristics and development process.Explore the relationship between ecosystem services and green space relationship.In the third part,based on the understanding of the existing green space layout pattern and the hilly city spatial layout and its evolution,the paper puts forward the"hub—link—node" network layout pattern of the hilly city green space,and draws the spatial layout pattern of different hilly cities The ideal layout of the green space layout.The fourth part systematically discusses the principles and methods of green space planning of hilly cities based on ecosystem services.Planning concepts and principles point out the ecological principles of planning ideology to respect nature,imitate natural transitions and green space planning.The planning method introduces the technical method of generating the green space network of the hilly city through the evaluation of the ecosystem service,and puts forward the multi—level spatial strategy and the concrete implementation management strategy.In the fifth part,through the green space planning of hilly city Changsha city to apply and test the planning method,reflects the practical value of theoretical research and planning methods of feasibility and reproducibility,but also provides a reference for the control of green space planning and coordinated development of hilly city development and protection.
