土地资源有限性与建设用地需求增长的矛盾加剧,建设用地增量控制亟需向总量管控转变,而合理分配区域间建设用地总量是实现其总量管控的前提。本文从区域社会经济发展需求和资源禀赋供给约束两方面,筛选出常住人口、GDP、建设用地可拓展空间、农村居民点整理潜力等影响建设用地总量分配的主要指标,兼顾效率与公平,构建基于基尼系数的建设用地总量分配模型,以综合基尼系数最小为目标函数,建立多约束的线性规划求解方程,得到2020年江苏省建设用地总量分配方案。研究结果表明：1基于基尼系数的建设用地总量分配兼顾了资源配置的效率和公平需求,提高了分配方案的合理性。基于基尼系数的分配结果与现行规划方案相比,综合基尼系数由0.330降为0.315,各指标的基尼系数都有不同程度的下降。2根据建设用地总量分配结果,结合建设用地现状规模,测算江苏省13个地级市现行扩张趋势下建设用地总量剩余空间的可使用年限,依据可使用年限与现行规划剩余时间的对比关系,将13个地级市划分为3类建设用地管控区域。苏州、盐城和徐州为合理缩减区,应按照＂严控总量,盘活存量＂的目标,实施建设用地减量化管理;南京、无锡、常州、南通、连云港、淮安和宿迁为优化调整区,应采取＂增量递减、存量优化＂的调控策略,逐步缩减新增建设用地规模;扬州、镇江和泰州为重点发展区,应适度增加年度新增指标配置,同时强化新增建设用地的供地门槛。

Increasingly serious contradiction between the limited land resources and the growing construction land demand reaches a consensus. Thus,it is necessary to transform construction land management mode from the incremental control to the total control. And reasonable allocation of the total construction land is the prerequisite. Construction land scale influence factors are selected considering the demand of socioeconomic development and the supply constraints of resource endowment,such as the permanent population,GDP,construction land expandable space and rural construction land consolidation potential. An optimization allocation model of total construction land is established with multi-constrained linear equations based on the Gini coefficient,which gives consideration to both the efficiency and fairness. The total construction land＇s allocation plan of Jiangsu Province is proposed with the aim of minimizing comprehensive Gini coefficient. The results show that： 1 the total construction land allocation method based on Gini coefficient,considering both the fairness and efficiency of resource allocation,improves the allocation rationality. Compared with the current allocation scheme,the comprehensive Gini coefficient decreased from 0. 330 to 0. 315,and Gini coefficient of each index decreases to some degree respectively. 2 The durable years of the construction land remaining space are estimated according to the current construction land and the allocation scale based on the Gini coefficient. Comparing the durable years and the current planning ＇s remaining years,the 13 cities in Jiangsu Province are divided into three types. The reasonable reduction zone,including Suzhou,Yancheng and Xuzhou,is necessary to reduce the construction land area to strictly control its scale and improve existing construction land use efficient. By comparison,the optimizing and adjusting zone,including Nanjing,Wuxi,Changzhou,Nantong,Huaian,Suqian and Lianyungang,is necessary to carry out the control strategy to gradually reduce the increment and optimize the existing construction land,so that the new incremental construction land will be reduced gradually. While the key development zone,including Yangzhou,Zhenjiang and Taizhou,can increase annual incremental construction land quota moderately,and at the same time,strengthen the threshold of the newly increased construction land.
