Abstract: Taking 5 periods of land use cover change (LUCC) from 1980 to 2010 as the data source, obtaining the data of urban and rural construction land changing in Jiangsu Province for nearly 30 years, supported by spatial and landscape analysis and other methods, this paper analyzed the characteristics of urban and rural space evaluation, evaluated the process and extent of the integration of urban and rural areas, aiming at revealing the dynamic mechanism of the development of integration of urban and rural areas, and summing up the regional model of the integration of urban and rural areas. The results show that: (1) In the aspect of spatial expansion of cities and towns, the quantitative change is characterized by the rapid growth after the first flatness. The spatial pattern changes are mainly from external expansion and then to the filling and expanding cycles between the patches. The urban spatial expansion among Suzhou, Wuxi, and Changzhou is the most intensive. (2) In the aspect of regional change of rural areas, a slight increase has been identified, and in the northern part of Jiangsu along the Huaihe River, rural construction land distribution is relatively intensive, and subdense area of rural construction land has been established along the river. (3) In the process of urban and rural integration, the spaces of both areas began to transit gradually from discrete to adhesive pattern, and the adhesive expansion in southern Jiangsu is the most obvious.(4) The dynamic mechanism and regional model of urban and rural integration, the rapid improvement of social economic development, the fast development of township enterprises, the continuous improvement of transportation infrastructure, and the swift construction of development zones and new urban areas are the main driving forces of urban and rural integration development in Jiangsu. According to the spatial characteristics and the main driving factors of urban and rural integration development, three different types of urbanrural integration development in Jiangsu Province can be identified: hublink mode, agglomerationannexation mode and integrating expansion mode.
