| Green space is an important part of mountain city,a necessary factor of building a green,livable,beautiful urban environment.The construction of urban green space system is the response to sustainable development,ecological civilization construction and the effective method of five development concept,mountain city green space system planning research is urban and rural planning and landscape garden disciplines.Before this study,relevant experts and scholars at home and abroad have made many achievements in the theoretical construction and technical application of green space system,which has laid a foundation for further expansion and further research into the construction of urban green space system.In the past four years,Chengdu has taken the lead in exploring a new urbanization path with Chinese characteristics,from the Park City demonstration area practicing the new development concept,and has made great achievements in theory and practice.As one of the most important cities in Sichuan and Chongqing region,Chongqing is the trend of The Times to sing the "tale of two cities" well and practice the concept of Park City construction.Chongqing,which is different from plain city Chengdu,has a complex terrain and its landform is hills and mountains.How to make better use of the natural landscape pattern of the city to serve the construction of green space system and create a Park City with unique urban style and urban characteristics is a question which is worth debating.However,under the background of Park City construction in the new era,there is little research on the urban green space system planning of mountain parks.From the perspective of Park City construction,the practice of mountain city green space system construction is still scarce,and the Park City is the inevitable direction of the future development of mountain city.Under the background of the new era of socialism with Chinese characteristics,it has distinct characteristics and reference significance to deeply explore the theory and practice of the optimization of urban green space system in mountain parks and cities.With the mountain urban green space system,the 19 cities with typical and representative landscape characteristics were selected as the research sample,based on the analysis of its natural landscape pattern and green space system,combined with the concept of a Park City,exploring the planning strategy of urban green space system in mountain parks.The specific research work includes three aspects: first,the Mountain Park City and the green space system are defined,summarize the development process from Garden City,Ecological Garden City to Park City,explain the similarities and differences of urban green space planning and construction in different modes.The needs of the residents in the mountain park urban planning and the construction goal of the mountain city green space system under the Park City concept are studied.The natural landscape pattern of 19 cities in China is analyzed,the relationship between urban form and mountains and water is summarized,and the relationship between mountains,water and city is summarized.Through the in-depth study of the urban layout and green space system structure under the influence of landscape pattern,the urban layout structure pattern and green space structure type based on natural landscape is summarized.Analyze the relationship between natural landscape and all kinds of green space,explore the ways to combine park green space,protective green space,regional green space and landscape pattern,and point out the advantages and resistance of natural landscape pattern on the construction of mountain city green space system under the current background of the Park City construction.The second is to study the urban landscape pattern and its influence on the urban layout and the green space system,and put forward the principles and technical methods of building the mountain park urban green space system based on the natural landscape pattern.Third,for Longxing New City landscape,this paper research the present situation of green space planning and construction,landscape pattern,analyzes the problems existing in the urban green space system planning and construction,using Park City construction ideas,the practice of Longxing New City green space system construction research,put forward targeted mountain park urban green space system planning strategy.The following conclusions are drawn:(1)The urban green space system planning mode from garden city,ecological garden city,park city development,urban green space system planning from a single function to function composite,from only for human service to harmony between man and nature,from point line planning to ecological network construction,from conceptual planning to multi-level planning.(2)The needs of residents in urban planning and construction of mountain parks include three aspects: first,to retain landscape environment,emphasize residents’ recreation experience and emotional cognition to form urban memory;the other is to generate visual connection of urban land in breadth,depth and level,construct multi-dimensional green landscape and strengthen the urban mountain landscape;third,to emphasize fairness and emphasize the spatial matching between public facilities and the distribution of resident population services.(3)The relationship between city and water is "water through the city","water holding city","water network city","city coastal";the relationship between city and mountain is "background mountain","connecting mountain","internal mountain" and "combination".The spatial relationship between cities and mountains and water is abstractly summarized into 16 types.(4)The layout of mountain cities is restricted by the natural terrain conditions,and it presents four types: centralized and compact layout,group layout,strip layout,and combined layout.The planning of urban green space system is particularly affected by the natural landscape pattern.Different cities form green heart,green belt,green ring and green wedge according to their own conditions.(5)Urban park green space established based on mountains,parks in the whole mountain or on the top,hillside and foot,and parks relying on water system resources can form strip parks,strip parks,dotted parks and island parks.The layout of park green space,square land,protective green space and regional green space needs to jointly build a mountain city green space system with landscape as the skeleton.(6)In addition to the general planning principles,four principles: the principle of landscape;the principle of overall consideration of plane and vertical;the principle of stimulating the multi-functional potential of landscape,and the principle of enhancing the multi-dimensional perception of landscape.The planning strategy of urban green space system in mountain park includes four aspects: planning of urban green space layout structure,building urban park recreation system by relying on natural landscape,building corridor system and building a perfect landscape sight system. |
