Study On The Layout Of Urban Park Green Space In Hexian County Based On GIS

At present,China has entered a new era.The problems of green space shortage and urban land shortage in the process of urbanization are gradually exposed.The strategic decision of ecological civilization construction came into being at the 18 th National Congress of the Communist Party of China.China has embarked on the great journey of ecological civilization construction.However,in the process of urban green space construction,the pursuit of quantity and area blindly ignores the quality of park green space and the accessibility of urban residents’ recreation,which also leads to the decline of urban residents’ happiness.Based on the research of urban green space layout and accessibility at home and abroad,taking the central city of He county in Ma’anshan City as an example,this paper explores the green space planning and layout scheme in line with the actual situation of small cities in China,and provides the basis for the future green space layout adjustment of He county.With the help of ArcGIS software network analysis,through the establishment of network data sets,the accessibility of park green space is evaluated.Through the weighted analysis of the influencing factors of park location,such as the feasibility of land construction and the accessibility of urban parks,the suitability of park green space location is evaluated,and the suitable area for park construction is determined.Combined with the field investigation,the proposed park area is delimited,so as to obtain the urban green space layout scheme in line with the actual situation of Hexian County,and put forward the construction idea of the northern landscape core;Combined with the park layout optimization scheme,the optimization scheme of urban disaster prevention and risk avoidance green space is further refined.On the basis of fully considering the needs of urban residents,the guidance basis for urban green space construction in Hexian county is provided.
