基于用地变化的苏北小城镇总体规划实施评估研究

Implementation of a small-town master plan based on land use change in the north of Jiangsu

【目的】探究苏北地区小城镇总体规划中用地实施情况,促进城乡用地布局的合理化。【方法】以江苏省泗阳县裴圩镇为例,利用ARCGIS、GEODA、ENVI等技术,建立裴圩镇总体规划用地实施评估指标体系,同时进行用地一致性、绩效性评估。【结果】以用地评估为评价目标,形成1个目标层、2个准则层、7个指标层的评估体系。根据指标体系评估结果,裴圩镇总规实施情况"一般",存在一定程度上偏离城镇发展方向、空间管制把控不严、用地布局结构有待完善、重指标轻布局等问题。【结论】对同类型小城镇总体规划的实施过程,建议"加强动态监测、增强空间管制、完善用地布局、增量转存量",以促进小城镇健康发展,该评估体系也丰富了小城镇总规评估的研究内容。

【Objective】The aim of this study was to evaluate the land use implementation of a small-town master plan in the northern part of Jiangsu Province and to promote the rationalization of land layout.【Method】This study used Peiwei Town in Siyang City,Jiangsu Province to establish an evaluation index system. The implementation of the evaluation index system for a master plan based on the land use of Peiwei Town employed ARCGIS,GEODA and ENVI techniques to formulate conformance-based and performance-based evaluations.【Result】We take the land use evaluation as the evaluation target,and form an evaluation system of one target layer,two criteria layer and seven index layers.The index system showed that the implementation of the plan was effective in general;however,there were still a number of problems in conformance-based evaluation,including,to some extent,deviating from the direction of town development,lack of space control,incomplete land use,and focusing more on the completion of indicators instead of on land use layout.Furthermore,the performance-based evaluation also had some problems,such as a weaker effect of land use aggregation than planned and a need for improvement of the coupling relationship between people and land.【Conclusion】This findings of this study will enable the proposal of a few strategies for small towns of the same types,including establishing a dynamic monitoring system,strengthening space control,improving the layout of land use,transferring the increment planning to inventory planning,and coordinating the relationship between people and land. All of the suggestions aim to promote the healthy development of small towns and enrich the research content for small town master plan assessments.
