Study On The Spatial Layout Of Urban Parks In Chenghua District Based On Park City Abstract

In the process of rapid urbanization,many ecological environment problems emerge in urban development,such as urban ecological environment degradation,uneven distribution of urban ecological resources,insufficient supply of urban ecological products and so on.Based on the concept of Park city,the construction of urban environment,urban public service system,urban space,urban industry,urban intellectualization,urban culture,urban quality and other aspects are facing higher requirements for upgrading and transformation.As an indispensable and important role in urban green space,urban parks are also an important part of urban public service facilities and an important medium for residents to share the results of urban construction.The spatial layout of urban parks directly affects the distribution of urban ecological resources and the efficiency of citizens' use.On the whole,the current urban park system is not perfect.Although there are many theoretical explorations in this field,there are still some deficiencies in the operational scheme of the urban park construction standard under the concept of Park city,but the strong operability and practicality of the design discipline can make up for the deficiency of the spatial layout of urban parks.Based on the research point of view of the spatial layout of urban parks,this paper emphasizes the current situation evaluation and optimization strategy of the spatial layout of urban parks under the new standard of urban construction proposed by the concept of Park city.The paper also explores the coupling relationship between urban park space and other urban spaces,and envisages the realization of resources,skills and knowledge among urban spaces by upgrading and improving the spatial layout.Mutual benefit makes urban parks more open,service coverage more extensive,and service efficiency truly shared by the whole people.In terms of research methods,this paper belongs to the cross-research fields of applied research which involve in the applied research fields,landscape architecture planning fields and urban design.The paper applies the theoretical viewpoints of landscape architecture,urban design,behavioral science and park city.By using the methods of literature research,investigation and research,geospatial analysis,qualitative and quantitative analysis,this paper puts forward feasible strategies for optimizing the spatial layout of urban parks under the concept of Park city.The main research results of this paper include the following aspects:Firstly,through analyzing and sorting out the relevant research contents of the spatial layout of Park City and urban park,the evaluation model of urban park spatial layout based on Park City is established.This paper evaluates the status quo of urban parks' spatial layout in Chenghua District from four indicators: openness,accessibility,service capacity and spatial overlay analysis.Secondly,the entrance and exit settings,the opening time,the charging situation and the surrounding traffic conditions of the selected parks are statistically sorted out,and the degree of openness of the park is comprehensively evaluated according to the sorted results.Thirdly,based on the related theory of spatial syntax,the axes of road network in Chenghua District are drawn.Variable parameters of spatial syntax are studied by using the research platform of Depthmap software.The visualization results of global integration degree analysis and regional integration degree analysis of road network in Chenghua District are obtained.According to the cold and warm degree of road color in the graph,the accessibility of urban road network in Chenghua District can be obtained.The accessibility of urban parks was evaluated.Fourthly,according to the size of the park,different service radius is set up and the service scope of the park is analyzed by using the buffer analysis function of ArcGIS.The service coverage of the urban park in Chenghua District is obtained,and the details of the service capacity of the park are obtained by overlapping analysis with the residential area and population activity density covered by the service atmosphere.Fifthly,using the point density analysis function of ArcGIS,the distribution maps of POI density and population activity density in Huahua District are drawn,and the spatial coupling analysis is carried out with the distribution of urban parks.In summary,the evaluation results of the current spatial layout of Chenghua urban parks are obtained.Sixthly,the corresponding optimization strategies are put forward according to the evaluation results of the current situation of the urban park spatial layout in Chenghua District.
