Spatial difference of urban and rural development level in the Cities along the Yangtze River in Anhui Province

Taking the Cities along the Yangtze River in Anhui Province as an example, the paper sets up a comprehensive evaluation system to evaluate the urban and rural development level in the cities along the Yangtze River in Anhui province in 2008, and uses the spatial autocorrelation model to analysis its spatial difference and spatial correlation. The results show: ①there are certain regional differences in the development level of the two systems; ② from the spatial correlation perspective, the correlation of the two systems is significant. And judging from the partial autocorrelation, Hefei is a “high - high” hot spot, Chizhou and Xuancheng are “low - low” areas, Chuzhou and Chaohu, Anqing and Lu'an are “low - high” heterogeneous regions, Ma'anshan, Wuhu and Tongling are “high - low” heterogeneous areas.
