Abstract：At present, rural and unban development are experiencing a transition period, from society, economy, culture and settlement spatial, rural become to urban transformation, meanwhile, different regions of the rural by urbanization influence degree differ, the area of rurality also showed significant differences. Every region can be regarded as a unity of urbanity and rurality, based on it, taked unban as criteria of reference to construct rurality index, and maked use of ESDA-GIS frame, by using spatial metric model such as spatial correlation index and semivarigram, the paper analyzed the spatial pattern and mechanism of rurality at county level in Jiangsu since the 1990s. The results show that: 1)Considering the overall spatial rurality framework, the county rurality of Jiangsu province showed a strong trend of spatial natural correlation, the similar areas cluster in space; 2)The spatial structure of hot-spot distribution tends to have a circular spatial structure centered on Xuzhou-Suqian-Huaian, and the hotspots have been remarkably increased after 2005, converging to Yancheng; there exists an obvious appearance of geographical concentration characteristic of spatial evolution according to the analysis of high-value clusters; 3)According to the space-time mechanism, the Jiangsu spatial rurality framework tends to be more continuous and self-organized, the random of the spatial differential pattern keeps decreasing and the mechanism of the structural differentiation caused by natural correlation in space is becoming more and more remarkable.
