研究目的:探讨小城镇用地扩张的机制,为小城镇土地利用监管提供理论依据。研究方法:文献综述法。研究结果:(1)小城镇用地扩张是小城镇土地利用系统外部冲击机制和内部传导机制相互作用的结果;(2)外部冲击主要来源于农地使用制度改革、户籍制度改革、城镇土地使用制度改革、城镇住房制度改革、城镇公共设施投融资制度改革和产业结构调整,内部传导机制主要包括需求机制、价值增值机制、供给机制、产业关联机制、容量约束机制和市场主体自律机制;(3)小城镇用地扩张过程可以分为外部冲击、初始响应和内部传导三个阶段。研究结论:小城镇用地扩张表现出明显的空间和时间差异性,小城镇用地扩张控制应因时因地而异。
The purposes of this study are to analyze the mechanism of urban land expansion in small towns and provide theoretical basis for administrating the land use in small towns. Documentation method was employed. The results indicated that( 1 ) urban land expansion in small towns was the result of the external shocks interacted with the internal factors of the land use system in small towns~ (2) The external shocks included that the reform of farmland system, census register system, township land system, township housing system, township public facilities investment system, and industrial structure adjustment; the internal mechanism included that the demand mechanism, supply mechanism, value increment mechanism, industrial connection mechanism, capacity control mechanism and self-control mechanism. (3) The process of the land expansion in small towns could be divided into three stages, i.e., the external shocking stage, the initial responding stage and the internal conducting stage. It is concluded that urban land expansion in small towns was significantly different in terms of space and time attributes. Therefore the controlling measures of urban land expansion in small towns should be diverse accordingly.
