| The basic condition of developing sports is sports land.Metropolitan area,especially Shanghai which is an extra-large city,needs to know accurately the base of sports land,understands the law of historical trend and deal with the contradiction between the demand of sports land and the demand of economic development land.This paper focus on the temporal and spatial change characteristics of sports land in Shanghai during 2000-2015 years(2000,2005,2010 and 2015),summing up theoretically and systematically the way and process using remote sensing and geographical information system to get sports land,analyzing sports land in Shanghai during 2000-2015,drawing the following conclusions:(1)In 2000,2005,2010 and 2015,the total area of sports land in Shanghai is 10157947 m2,23854770 m2,26668118 m2 and 29565378 m2 respectively.In the past 15 years,the total area of sports land has increased by about 19.4 km2,the number of sports land has increased by 135.The proportion that sports land accounted for total urban area has increased by 0.267 percent.The proportion that sports land accounted for building land has increased by 0.511 percent.The average sports land of registered population has increased by 1.281 m2.The average sports land of permanent resident population has increased by 0.593 m.(2)From 2000 to 2015,except the average sports land of permanent population,the other 5 sports land index(the number of sports land block,the area of sports land,the proportion that sports area accounts for the total urban area,the proportion that sports lands accounts for building area,the average sports land of registered population)has increased year by year.(3)In 2015,there are 200 sports land block and over 29 km2 sports land in Shanghai.The proportion that sports land accounts for building land is 1.137 percent.The average sports land of permanent population is 1.224 m2.The average sports land of registered population is more than 2 m2.These indices have improved greatly compared with those in 2000.(4)Changes in spatial distribution of 2000-2015 for Shanghai city sports have the following features:the overall spatial distribution of sports land gradually expands where takes the central city center and the suburb center town as the core;the expanding for sports land in the outer ring mainly develops in Pudong area.The development of sports land outside the outer ring is most obvious in the west and southwest of the central city.(5)Between 2000 and 2015,except for very few regions and years,the sports land use index for the jurisdiction of Shanghai showed a gradual growth trend,but the growth rate of the suburbs was significantly larger than the central city.(6)In 2005,per capita sports land for resident population in Shanghai reached 1.262 m2.It has improved greatly which compared with 2000.For the next ten years,although the city’s sports land area has increased,because of the rapid growth of population,person sports land for resident population in Shanghai has been stable at 1.2 m2.This paper points out that in the next 5-10 years,Shanghai,especially the central urban area,needs to allocate land resources reasonably and enlarge the scale of sports land to help dealing with the problem that the average sports land in central area is too small.This research helps deepening the understanding of the temporal and spatial change characteristics of sports land in Shanghai and provides suggestions for solving the problem of the supply of sports land in Shanghai. |
