Evaluation of the Service Efficiency of Urban Park based on Morphological Differences——The application examples of ARCGIS reachability analysis

This paper uses reachability analysis provided by ArcGIS software,by taking the example of Nanchang Ganjiang Citizen’s Park and Bayi Park,to find the relationship between the park morphology and service efficiency.The study shows that,the strip urban park has a higher efficiency than the massive urban parks,green belts are a very efficient form of public green space in the urban green space system.Finally,the paper gives the introduction of service efficiency to the evaluation system of urban green space planning as an new indicators to improve the scientific of the evaluation system.
