Spatial Pattern and Driving Force of Public Sports Facilities in Changsha City
Taking the public sports facilities in Changsha City as the research object,using the Kernel Density Analysis,Standard Deviation Ellipse and Average Nearest Neighbor Method,the spatial distribution pattern of public sports facilities in Changsha City is obtained:(1)The layout of public sports facilities generally presents a"northwest to southeast"directional trend,which is consistent with the"Xiangjiang Comprehensive Service Belt"and"East-west Development Axis".(2)The layout of public sports facilities is relatively compact,the average distance is less than 500m,and the overall pattern is"1+2"across the river.The highest concentration effect area is located in Yuelu Street and Juzi Street.Then,the driving mechanism behind the spatial layout of public sports facilities in Changsha City was further explored by using the geographical detector.The results showed that:(1)the influence of human factors was greater than that of natural factors,with the population density factor having the largest influence(0.509)and the terrain factor having the least influence(0.004).(2)The influence of any pair of factors on the spatial layout of public sports facilities was significantly increased after interaction,among which the interaction of terrain factors with vegetation coverage factors,road traffic factors,population density factors and economic base factors showed nonlinear enhancement,and the enhancement effect of factor influence was significant.
