The Research On The Accessibility Of Recreational Green Space In Yuelu District Of Changsha City

With the advent of the national leisure era,people are paying more and more attention to recreational activities.Recreational green space,as an urban green space open to the public,is the main carrier of recreational leisure activities,and an important part of urban green space.Construction has played an important role.With the proposal and implementation of garden cities,the number of urban recreational green spaces has increased significantly,but the current evaluation of urban green spaces is mostly measured by indicators such as per capita green space area,green space rate,green coverage rate,etc.It is difficult to judge the service level and distribution of green land Rationality.Therefore,from the perspective of accessibility,this article studies whether the urban recreation green space is reasonably distributed.Based on the relevant theories of green space accessibility at home and abroad,this paper takes the recreational green space in Yuelu District of Changsha as the research object,combined with the current situation of the recreational green space and population distribution,etc.,based on real-time traffic data under different travel modes in the GIS platform The overall analysis and classification analysis of the accessibility of recreational green spaces show that the research area has reached a high level in the traditional green space evaluation indicators,but the distribution of various types of recreational green spaces is uneven,except that it can be achieved under the motor vehicle mode.The service area is fully covered,and other travel modes have different levels of service blind areas;road construction has advantages and disadvantages.While improving the efficiency of motor vehicle travel,the road also affects the accessibility of walking and cycling to a certain extent;different streets The coverage of service areas varies greatly,and the use of recreational green space resources lacks fairness.Based on the analysis and evaluation of accessibility,the corresponding optimization strategies are proposed for the main contradictions: First,based on the accessibility results and street development,we will formulate temporarily no additional recreational green space,and mainly build daily recreational green space,Multi-level construction of recreational green space,and the expansion of holiday-type recreational green space as the main four layout optimization schemes.Secondly,the opening of recreational green space is enhanced by adding the entrance and traffic guidance of recreational green space.Third,strengthen the spatial connection between public transportation and recreational green spaces,improve the construction of the BRT system,and increase the capacity and attractiveness of public transportation.Finally,improve road construction from the two levels of greenway and open street,form a road network with reasonable road gradation at all levels,create better slowtravel conditions to improve accessibility,and realize the harmonious coexistence of slow-moving and motor vehicles.
