Spatial Equity of Urban Parks in the Central Urban Area in Nanjing Based on Different Transportations

The urban parks are an important part of urban public resources. Evaluating the equity of their spatial layout and the reasonable degree of resources allocation is helpful for proposing targeted optimization strategies. Based on analysis of parks accessibility in central urban area of Nanjing in different transportation modes, this paper calculates park resources allocation by Gini coefficient and Lorenz curve drawing to make the overall evaluation of the rational distribution of urban park resources. The paper assesses the spatial pattern of parks distribution in five transportation modes by section quotient. Changing transportation mode is conducive to improving the reasonable level of city parks distribution. Considering population demand, park planning should be carried out according to local conditions, green patches should be inserted, greenway construction should be promoted, and green travel should be advocated, which is conducive to the rational allocation of urban park resources, improvement of service value of urban parks and building of a living-friendly city.
