Research On The Urban Green Space System Planning Of Lintong District Under The Concept Of Urban Agriculture

The unscrupulous expansion of the city has led to a sudden reduction of agricultural land and a pattern of urban-rural opposition,which makes people aware of the urgency of the harmonious development between urban and rural.Urban green space system has always been the important carrier of urban and rural harmonious development,and it is also important for the ecological environment of the city.So that,more and more professionals began working on the problems that green space system being caused by rapid urbanization and the ecosystem edge fragmentation.The new urbanization policy also emphasizes the importance of ecological civilization construction,therefore urban green space system planning should pay more attention to the protection of ecological environment.Urban agriculture,with its unique landscape and ecological functions,can provide better ecological service value to the urban green space system,and the urban agriculture,located in the fuzzy zone of urban and rural areas,is a breakthrough point to break the boundary and promote the coordinated development of urban and rural.Against this background,urban agriculture will become an indispensable part of sustainable development of China.Although in recent years,scholars have paid more and more attention to the spatial pattern and the function of ecosystem services of urban green space system.However,from the perspective of urban and rural integration,it is relatively rare for the planning strategy study of the urban green space system which integrated with urban agriculture.This paper takes the urban green space system planning of lintong district as the research object,discusses the green space system planning method and the green space pattern under the integration of urban agriculture.First of all,within the scope of the city level,the article puts forward the possible forms of urban agriculture and the spatial carriers of urban agricultural development.Secondly,in the urban built-up area level,the article from three types of land that are most likely to integrate into the green space system to put forward the integration of urban agriculture,namely park green space,protective green space,attached green space.The study area is located in the edge of the metropolis,carrying the functions of food safety,hospitality pleasant,ecological barrier,and ecological security in Xi'an.Since the adjustment of the administrative division of Lintong District,urban expansion and rapid urbanization have caused serious occupation of its urban agricultural land,and the ecological service of urban green space system is facing threats.It is needed for the space of urban green space should be integrated rely on the existing national tourist cultural attractions in Lintong district to form a collection of tourism,leisure,ecology and scenery to make Lintong be a urban eco-functional zone of Xi'an.Firstly,from established geographic conditions,historical conditions,natural landscape,and urban agriculture development advantages four aspects,this paper have established the superiority of developing urban agriculture,further from the city of Xi'an special green space system planning of Xi'an city green space system planning and the overall plan for Xi'an established under the zoning planning of green space system planning established in the city proper two levels found in master planning established the existing problems in the development of suburban agriculture and agriculture in the built-up area.Finally from the perspective of quantitative analysis of urban agriculture established the ecological service value and accessibility analysis of urban agriculture layout,it aims to explore and maximize the ecological,productive and living benefits of urban agriculture,and contribute the best ecological service function to the urban green space system of Lintong district and even the urban green space system of Xi'an.At the last part,according to the principles of ecology,systematization,scientific and sociality,this paper puts forward the conception and planning of the urban green space system in Lintong district.Then combining the "patch corridor matrix" theory of landscape ecology,this paper reasonable organizes the urban agricultural landscape based on the core urban agricultural function area,the corridor of the river mountain forest,the patch scale intensive agriculture as the patch,so that it can maximize the ecological service function of urban agriculture,and rely on the multi-point radiation of the urban agricultural park to promote the agricultural development of the whole region.Thirdly,according to the classification of green space in the existing built-up area green space system,this paper proposes to bring the urban agriculture into all kinds of urban green space,and put forward the possible forms of urban agriculture in all kinds of urban green space based on the agricultural industrial base of Lintong district.In summary,this paper combines urban agriculture that has urban-rural integration,landscape ecology,intellectualism and urban green space that includes the landscape pattern and landscape green space of the city to realize the unified planning.It aims to construct more complete urban landscape ecological pattern in order to solve the problems facing the development of urban green space system in China and promote sustainable development of urban ecology.
