2023赛季中国职业足球俱乐部的空间分布特征

Spatial Distribution Characteristics of Chinese Professional Soccer Clubs in the 2023 Season

使用地理学理论和GIS技术进行分析,探讨2023赛季我国职业足球俱乐部的空间分布情况,结果表明:1)中国职业足球俱乐部的分布整体上呈现东强西弱的空间格局,其中在宏观区域尺度和省级尺度的分布为聚集型且分布较为集中;2)经过基尼系数、不平衡指数、地理集中系数和洛伦兹曲线等方法的研究分析发现,中国职业足球俱乐部的分布均衡性与空间尺度有关,且集中度都较高;3)通过核密度图得出中国职业足球俱乐部的高密度区主要为江浙沪地区;中高密度区主要在江浙沪外围圈层以及湘鄂赣三省交界处、珠三角地区和京津冀地区。低密度区主要位于东北、黔东南区域,以及中高密度区的外围圈层。

This paper uses geography theory and GIS technology to analyze the spatial distribution of professional soccer clubs in China in the 2023 season,and the results show that 1)the distribution of professional soccer clubs in China as a whole shows a spatial pattern of strong in the east and weak in the west,among which the distribution at the macro-regional scale and provincial scale is aggregated and more concentrated.2)After the research and analysis of Gini coefficient,imbalance index,geographic concentration coefficient and Lorentz curve,it is found that the distribution equilibrium of Chinese professional football clubs is related to the spatial scale,and the concentration degree is high.3)Through the nuclear density map,it is concluded that the high-density area of Chinese professional soccer clubs is mainly in Jiangsu,Zhejiang and Shanghai;the medium-density area is mainly in the outer circle of Jiangsu,Zhejiang and Shanghai and the junction of Xiang-E-Gan provinces,the Pearl River Delta region and Beijing-Tianjin-Hebei region.The low-density area is mainly located in the northeast and the southeast region of Qiandong,as well as the outer circles of the medium-high-density area.
