摘要
通过构建基于相对资源承载力的建设用地总量测度模型,测算江苏省62个县(市、区)规划目标年建设用地合理规模,据此划分建设用地管制区域,并探索区域差别化的建设用地管制思路。研究结果表明:①优化开发区单位建设用地二、三产增加值373.93万元/hm2,资源禀赋较好、经济高度发达,其所能承载的建设用地规模也较高,是江苏省建设用地规模合理扩张的优先区域;适度开发区单位建设用地二、三产增加值168.89万元/hm2,建设用地仍有一定拓展空间,可以允许其适度扩张;合理缩减区单位建设用地二、三产增加值115.20万元/hm2,建设用地规模已超出其资源承载力,满足其建设用地需求应立足存量挖潜;快速缩减区单位建设用地二、三产增加值仅为74.37万元/hm2,未来建设用地增长受到农业生产布局、生态环境保护的约束较大,集约利用水平亟待提升。②应结合区域资源禀赋、社会经济发展特征,制定区域差别化的建设用地管制措施。优先开发区在不突破土地开发强度约束的条件下允许其建设用地规模适度增加,同时配置较多的年度新增建设用地指标;适度开发区可适当扩大建设用地规模,适度增加其年度新增建设用地指标,并严格设定新增建设用地集约利用门槛;合理缩减区应合理控制年度新增建设用地指标,适当扩大城乡建设用地增减挂钩规模,探索建设用地减量配置方案;快速缩减区应立足存量挖潜,严格控制年度新增建设用地指标,合理测算城乡建设用地增减挂钩规模,探索建设用地减量配置方案和城乡建设用地置换指标的跨区域流转。
This study establishes the model of total amount about construction land, which can measure the reasonable size in the target year for the 62 counties of Jiangsu Province, based on the relative carrying capacity of resources. According to the quantity relation, construction land control zones are classified. The regional differentiation approach about construction land control is explored. The results indicate that： （1） In the priority development zones, there are abundant resources and the economy is well developed, the added value of secondary and tertiary industries unit construction land reaches 3. 739 3 million RMB per hectare. It is the priority zones to expand construction land in Jiangsu Province. In the moderate exploitation zones, the added value of secondary and tertiary industries unit construction land reaches 1. 688 9 million RMB per hectare, there is still the some potential to expand construction land, and therefore it is feasible to reasonably increase the construction land. In the reasonable reduction zones, the added value of secondary and tertiary industries unit construction land reaches 1. 152 0 million RMB per hectare, and the construction land amount has already exceeded the resource bearing capacity, it is necessary to tap potential from the existing construction land in order to meet the demand of economic development. In the rapid reduction zones, there is a very low added value of secondary and tertiary industries unit construction land, reaching 0. 743 7 million RMB per hectare, and the future expansion of construction land is greatly restrained by the spatial pattern of agricultural production and ecological environmental protection, and therefore it is urgent to improve the level of intensive utilization of construction land. （ 2 ） The differentiated rules of zone control for the construction land should be formulated according to the specific conditions of regional resource endowment and socio-economic development. In the priority development zones, it is feasible to reasonably increase the construction land under the top constraint condition, and arrange more annual incremental construction land quota. In the moderate exploitation zones, the construction land area can be increased properly and there can be more annual incremental construction land quota, whereas it is necessary to set strict intensive use thresholds for the newly increased construction land. In the reasonable reduction zones, it is necessary to reasonably control the annual incremental construction land quota and properly increase the linking scale, which contains the increase in urban construction land and the decrease in rural construction land. Configuration schedules for reducing the construction land are also needed to explore. In rapid reduction zones, more efforts should be made to further exploit the stock of construction land, and it is necessary to strictly control the annual incremental construction land quota, and reasonably determine the linking scale. The cross-regional transfer of the exchange quota and configuration schedules for reducing should be explored.
