摘要: 选取1980~2010年5期土地利用/覆被变化(LUCC)作为数据源,获取江苏省近30 a的城乡建设用地变化数据,在空间分析和景观分析等方法支持下,分析城乡空间形态的演变特征,揭示城乡空间融合的过程和动力机制,并归纳不同类型的城乡空间融合模式。结果表明:(1)城镇空间扩展方面,数量变化呈先平缓后急剧增长特征,空间形态变化首先以外部扩展为主,然后进入斑块边缘间的填充扩展的循环过程,苏锡常地区城镇空间的扩展最为密集;(2)农村地域变化方面,总量呈小幅增长态势,江苏北部沿淮河地区农村建设用地分布较为密集,沿江地区逐渐形成农村建设用地的次级密集区;(3)城乡空间融合过程方面,城乡空间开始由离散扩展逐步向粘合扩展过渡,城乡连通程度逐步提高,苏南地区城乡粘合扩展最为明显;(4)城乡空间融合的动力机制和地域模式,社会经济发展水平的快速提高、乡镇企业的高速发展、交通基础设施的不断完善、开发区和新城区的快速建设是江苏城乡融合发展的主要驱动力。依据空间形态变化特征和主要动力因素,江苏省具有3种城乡空间融合发展类型:枢纽链接模式、集聚吞并模式、融合扩展模式。关键词: 城乡融合;建设用地;空间形态;地域模式;江苏省

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. Key words:urban and rural integration; construction land; spatial form; model of regions; Jiangsu Province
