基于村庄调查的城乡建设用地增减挂钩潜力研究

从城乡建设用地增减挂钩的内涵和要求出发,分析了现有居民点整理潜力测算方法的利弊,提出了城乡建设用地挂钩的潜力调查及测算方法。以随县为例进行了实证研究,得出其规划目标年(2020年)按人均用地指标法推算的随县居民点整理理论潜力为8 314.66hm2,城乡建设用地增减挂钩项目规模可达到1 003.58hm2,扣除安置用地,挂钩指标可达805.47hm2。研究表明:采用现有的农村居民点整理潜力的测算方法测算的潜力是理想条件下增减挂钩的最大潜力;而实际潜力需要在拟定拆旧和安置地块基础上,通过实地核实图斑,推算整理复垦新增耕地面积,以及因安置占用的耕地面积,由此推算挂钩潜力指标。

Study on Potential of Linking Increase and Decrease of Construction Land in Both Urban and Rural Areas Based on Villages Survey

From the connotation and requirement of linking the increase and decrease of construction land in both urban and rural areas,this paper analyzes the advantages and disadvantages of present calculation method and its sources of rural residential land reclamation potential and puts forward the potential survey and its calculation method of linking the increase and decrease of construction land in both urban and rural areas.Based on the case study in Suixian county,this paper obtains the theoretical potential of rural residential land consolidation,that is 8 314.66 hm2 by the year of 2020 by index of land area per capita.The project size of linking the increase and decrease of construction land in both urban and rural areas can reach 1 003.58 hm2 and its index attainability is 805.47 hm2 by deducting the settlement land area.The result shows that the potential of rural residential land consolidation calculated by existing method is the maximum potential under ideal conditions,but as for the realistic potential of rural residential land consolidation,it first should make clear the demolition and settlement land area,then through verifying the map spot in the field,the newly added cultivated area of consolidation and reclamation and occupied cultivated area by resettling can be reckoned.Consequently,the potential index of linking the increase and decrease of construction land in both urban and rural areas can be calculated.
