随着土地利用总体规划实施的推进,对土地利用总体规划的评估也日渐引起人们的重视,目前已经成为评价规划实施成功与否的关键环节。当前的评估多数是通过建立指标体系进行数量上的评估,这种评估不能反映土地利用在空间上的差异。本文以江苏省泗洪县为案例,借助GIS的空间分析功能,构建了空间吻合度、重心偏移、环形系统3个模型,分别从规划执行过程空间吻合性、规划执行结果空间吻合性、建设用地重心偏移及土地利用空间布局等方面,对土地利用总体规划的空间实施效果进行评价。采用这3种模型,实现了"数量评估"与"空间评估"的结合,对土地利用总体规划评估的方法体系是有补充。
Overall land use planning of a certain region is the spatial and temporal arrangement and layout of land utilization types according to physical,economic and social conditions and regional requirements. More important is the strict implementation of planning text. Evaluations of implementation of general land use planning are an indispensable part of general land use planning and an important part of the planning implementation phase. Most of the current research has evaluated using the index system,but this does not reflect land use differences in space. In this paper the implementation effects of general land use planning were evaluated from spatial concordance during the implementation process,the spatial concordance of the implementation outcome,the shift of the barycenter of construction land and the layout of land use patterns by the spatial concordance model,the shift of barycenter model and the annular model with the aid of GIS software. Sihong County in Jiangsu was chosen as the study area for testing the applicability of the above-mentioned models and the models proved to be suitable tools in the assessment of enforcement effects of general land use planning. The evaluation models combine quantitative assessment and spatial analysis altogether and the results could be used in guiding the further actualization of general land use planning. Our study not only enriches the methodology of general land use planning evaluation but also provides constructive guidelines of better actualization of land use planning for local governments.
