Study On Layout Of Small Towns Green Space Based On Ecological Infrastructure

China is in a period of rapid development of urbanization, the construction of small towns which is in the initial stages is particularly important.Urban green space system is a green barrier to ensure the town healthy operation, to a large extent, which affects the overall development of the town. Whether the urban green land can exert the most synthetical benefit is closely related with the right layout structure.The paper will base on ecological infrastructure to study on layout of small towns green space and related planning theories and methods. The paper is taking Jingzhou county as a example,constructs the layout of small town green space from "macro-meso-micro" level,forming the optimal whole pattern and development strategy in the different scale.The main results are as follows:(1) The paper investigate,analysis and sum up the characteristics of small towns green space layout and its main problems.(2) This paper illustrates the impacts of ecological infrastructure on green space layout, pointing out differences between based on the ecological infrastructure of urban green space layout and based on the traditional method of green space layout and the necessity to combine the former with the latter.(3) Discussed study contents and methods of small towns green space layout based on ecological infrastructure and pointed out the principles to be followed, characteristics and the objectives to be achieved.(4) The macro-scale focus on the ecological frame construction under the environment from the city, region, county level. The structure of urban green space system in Jingzhou county is about:one-core, multi-point, two-sheets, four-axises, five-lines; The pattern of propose conservation of plant diversity is about:three-parks, four-regions,four-axises,four-passages; At the same time,the arcticle analyzes present conditions about cultural heritage, and propose three recommendations about cultural heritage protection:the establishment of landscape and cultural heritage corridor, eventually forming heritage landscape networks; pay attention to the overall protection of the landscape cultural heritage, perfect the system of transport and services.(5)The meso-scale stresses the connection between big environment and small environment within planning area range, in which proposes the structure of urban green space system:one-ring,one-axis, three-mountains, greenway into the city, and propose development strategies about corridor system and recreation system of planning area.(6) The micro-scale develops the suitability of land by means of GIS, proposes the structure of green space system in urban area combined with the overall planning and development, greenland status, cultural landscape:one-core, two-axises, six-parks, multi-gallery, multi-point; The paper study on the park system in urban area and analysis the accessibility of park planning before and after under the GIS suporrt, presented development strategies about future park construction.At last,proposed construction of the vision and development strategy about the Qujiang river corridor planning in order to form available mode for reference about the urban area corridor construction.
