Study On The Planning Methods Of Ecosystem Services In Urban Green Space System In Tongjiang

In today’s society, global ecological environment has been severely damaged. Survival crisis people began to re-examine the relationship between humans and nature, focusing on sustainable urban development. Urban green space with its rich variety of functions, the status of building in the city is becoming increasingly important. Urban Green System is a system of various green method according to scientifically organized to form green space system with a reasonable structure, enhance human activity and the maintenance of urban residents in health to provide material products, the ability of environmental resources, ecological and aesthetic values of public service. This capability is called ecosystem services of green space system of urban green space system planning goal is to enhance the ecosystem services of green space system, building green ecological services fully functional system.In this paper, Tongjiang County, Sichuan Province Green System Planning Practice project, based on the perspective of ecological functions and services, in order to play to the crowd of green space system services as an entry point for planning, summarized five major ecological green space system services classification system, and proposes meet the functional elements 6 large green space system planning. By constructing "the county- the county planning area- county land for construction," three levels of the planning system, to focus on the green space system planning elements optimized to play in promoting ecosystem services of green space system the functional elements of a positive effect, to build fully functional purpose green space system.First, on the basis of theoretical research, definition of ecosystem services of green sound system, the starting point will be based on multi-level needs of people to arrive at the ecosystem services of green points system. At the same time summarizes the constituent elements of green space system capabilities, the introduction of the authority of the ecological service function elements system at this stage, to extract the final summary includes security services, regulating services, support services, recreation services and cultural services, including five green system elements of ecosystem services.Then, combined with Tongjiang County, Sichuan Province Green System Planning Practice this project, proposed local planning and design ideas to the general, and to determine the breaking point the county, the county and the county planning area of land for construction large 3-level green space system planning and focus. County-level focus from security green, water environmental regulation green and biological conservation green 3 large spatial elements start to build the county ecological network backbone; county planning area level focus from suburban green space protection, water newspaper green, production green, countryside recreation green and landscape node space five space elements to start, build ecological protection barrier county to build the county ecological network backbone; county construction land level focus from security green, three-dimensional green technology, exchange places green, historical and cultural protection of green space, Landscaped green space five elements to start, create a rich living space.Finally, the summary based on green space system planning and design ways to promote system health, and from the research point of view and research ideas departure summed up innovation research, hoping to provide some references for Green System Planning and Construction of the city; also pointed out that research exists insufficient, and planning for the promotion of green space system function and healthy development of the practice put forward their own vision.
