Valle Research On The Green Space System Planning Of Chongqing Y-type Town

Chongqing, districts and counties city greening construction has developed rapidly. But, in many small cities, especially city small valley, due to the restriction of the natural environment and various socioeconomic factors, the far lagging behind the development of the city green space construction speed, and failed to give full play to urban peripheral green space landscape, ecology, aesthetics etc multiple effect, highlights the canyon type small city three-dimensional space characteristics, to show its unique regional style canyon. Valley type of urban green space system planning, should begin from area green space environment, using the landscape ecology, landscape aesthetics, theory of sustainable development, as a whole the inside edge of the city green space and urban built up area green space system of harmonious and orderly development, to establish an ecological harmony, landscape features prominent, the integration of urban and rural comprehensive green space ecosystem.Based valley type small city region space characteristics, firstly from the two aspects of natural environment and social environment in this paper, the influence of chongqing valley type small main influence factors of urban green space system layout. Then to peng, fengjie, small type in kaixian county in three gorge construction status quo of city green space system as the research object, using field investigation and related software to the cun-ent situation of green space system combined qualitative and quantitative comparative analysis, summed up the canyon model in chongqing urban green space system planning has a good macro greening condition, the layout of the three-dimensional structure and morphological characteristics such as natural ecological network. But, in the research, the author also found many problems, such as urban green space system planning lacking the overall consciousness, contributed to the canyon landscape ecological resources waste; Due to the urban construction and expansion, the mountain resources damage; Urban built up area green space layout is not reasonable; Urban internal, line, color, etc of the scale of the building do not coordinate with canyon environment, led to the valley city and green rate lower and lack of features, etc. To summed up the general characteristics and the main problems, the author put forward from three aspects for chongqing valley type small city green space system planning strategies:1) based on valley city region space characteristics of valley type small city green space system planning can be divided into planning green space and urban visual area of two levels;2) use of valley city green space system with three-dimensional layout structure characteristics and natural ecological network form two aspects, the landscape layout of urban green space system planning to become (?)"green patches, green corridors, green matrix\" as the leading3d ecological network;3) in view of the valley city contour lines, across the element, node and landmark landscape, regional landscape and unique landscape elements. Makes visual landscape of the systematic construction, reasonable layout of urban green space, to shape the visual landscape in the city of valley type characteristics. Thesis finally through WuXi county green space system planning practice, raised the theoretical guiding significance to the planning strategy.Thesis from the macroscopic to the microscopic level model is put forward in view of the valley of chongqing urban green space system planning strategy, in order to highlight the canyon type small urban green space characteristics in three dimensional space, shows its unique regional style, enhance the image of the city charm, also hope to chongqing region outside the valley type to provide some thinking to the small city green space system planning practice.
