当前形势下土地利用总体规划中功能分区方法研究——以宜兴市为例

Functional Zoning Method in Comprehensive Land Use Planning Under Current Situation——A Case Study of Yixing City

当前形势下土地利用总体规划的功能分区应进一步强化科学发展理念,除了要突出土地利用现状要素外,同时需要强调其与社会经济、生态保护的协调,以达到土地利用综合效益的最大化。本文在这种理念的指导下,首先提出了土地利用总体规划中耕地保育潜力、经济与建设开发潜力、生态保护潜力的功能分区指标体系及其定量方法,确定了各组合所对应的功能区类型。然后,综合考虑资源、经济、生态特征组合,并结合土地利用现状,采用聚类方法,以镇(园)为单元对宜兴市土地利用进行综合功能分区,将功能区划分为优先发展区、适度发展区、适度保护区、禁止发展区和灰色地区等5类土地利用功能区。文章最后从社会经济角度分析了各功能区的特征,提出了土地利用方向与措施。

Under the current situation, the conception of scientific development should be further strengthened in functional zoning for comprehensive land-use planning. In addition to stressing factors of the current land use status, it is also essential to emphasize its harmonization with socio-economic development and ecological protection, so as to maximize the comprehensive benefit of land use. Guided with the conception, the authors put forth a functional zoning index system and its quantification method for evaluating cultivated land preservation potential, economic and constructive development potential, and environment protection pontential, and define types of function zones corresponding to different combinations. And then, based on integrated consideration of various combinations of resources, and economic and ecological characters, and land use status, the authors adopted the clustering method to carry out comprehensive function zoning of land use in Yixing with town as unit. Five function zones were defined as priority development zone, moderate development zone, moderate protection zone, development prohibited zone, and grey zone. Finally, the authors analyzed characteristics of each function zone from the angle of socio-economy, and suggested direction and controlling measures of land use in Yixing.
