【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30a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。
[Abstract]:Land use / cover change (LUCC) data of 5 periods from 1980 to 2010 were selected as data sources to obtain urban and rural construction land change data for nearly 30 years in Jiangsu Province. With the support of spatial analysis and landscape analysis, this paper analyzes the evolution characteristics of urban and rural spatial form, and reveals the process and dynamic mechanism of urban-rural spatial integration. The results show that the quantity change of urban and rural spatial expansion is first gentle and then sharp, and the change of spatial form is mainly external expansion. Then enter the circular process of filling and expanding between the patch edges, the expansion of urban space in Suxi-Chang area is the most intensive. (2) the rural area changes, the total amount presents the small increase tendency, the northern Jiangsu Province along the Huaihe River area countryside construction land distribution is denser, along the river area gradually forms the rural construction land sub-dense area; 3) in the process of urban-rural spatial integration, urban and rural space began to transition from discrete expansion to adhesive expansion, and the degree of urban-rural connectivity was gradually improved, especially in southern Jiangsu; 4) the dynamic mechanism and regional pattern of urban and rural spatial integration, the rapid improvement of social and economic development, the rapid development of township enterprises and the continuous improvement of transportation infrastructure. The rapid construction of development zones and new urban areas is the main driving force for the integration of urban and rural areas in Jiangsu Province. Jiangsu Province has three types of urban and rural spatial integration development: hub link mode, agglomeration and annexation mode, integration and expansion mode.

【正文快照】： 城镇和乡村系统在生产结构和发展规律等方面存在较大差异,且一直存在“重城镇、轻乡村”的不平等关系。但两者同为人类的聚居单元[1],它们是一个相互联系、互为条件、统一的整体。自霍华德(1898)提出城市和乡村必须结合[2],到芒福德(1961)指出城与乡不能截然分开,应当有机结合
