| In the 21st century,rapid social and economic growth,the urbanization process continues to advance,and cities continue to expand outward.At the same time,a series of issues related to land use,resource utilization,and ecological environment have gradually been exposed.Research in this area has also changed from a development-first-governance model to a primary priority.The construction of the ecological environment has gradually become a core point for measuring the perfection of urban planning.As an organic part of a modern city,urban green space is the natural foundation for constructing and supporting the urban ecological environment,the only urban infrastructure with vital characteristics,and also an important foundation for the sustainable development of urban society and economy.However,in the actual urban green space planning,many urban park green spaces have blindly followed up in terms of planning positioning,landscape layout,scale structure,etc.,lacking more human considerations,whether residents can easily and conveniently reach green spaces,green Whether the spatial layout is compatible with the surrounding environment,how to integrate it into the overall design and planning of the city,and how to create a higher quality,convenient and efficient park green space,has become a hot topic in urban green space construction.Based on the current overall urban planning of Anda City and the site selection of park green space at this stage,taking the current status of the park green space and the recently planned layout of Anda City as the research content,through field visits and surveys,the current status of park green space construction is obtained,combined with government work The report and the new round of urban planning have combed the park green space layout,urban environmental construction goals and policy guidance,and played a leading role in further park layout optimization;Through the GIS platform,extract the data of roads,residential areas,parks and green areas in the central city,construct urban road network data sets,establish a spatial network analysis database,and analyze the space of parks and green areas based on the service range of urban parks and the convenience to residents Accessibility,according to the results of accessibility analysis combined with urban green space system planning to make a preliminary optimization adjustment strategy;Combining the ecological service function and social service function of the park,from the perspective of the suitability of site selection,select important single-factor influencing factors affecting its site selection,and quantitatively analyze each factor to determine the weight of the factor.Weighted overlay analysis,on the basis of accessibility analysis,evaluates the suitability of park site selection,delineates areas suitable for park construction,and combined with field research,selects the proposed candidate points according to different urban park categories to form Reasonable structure and layout of park green space.Then use the GIS location allocation model to select the priority construction parks among the candidate points,and at the same time extract the construction and optimization strategies of ecological residential areas and disaster prevention and avoidance park green spaces,and combine the plant configuration and different functions to build the park.An extension study was conducted.To meet the rigid needs of residents for parks,optimize the construction of urban parks,assist the government to give priority to ecological control,select suitable areas for park construction with high social value,and provide scientific basis for priority construction of park projects. |
