基于主体功能区的土地规划新增建设用地指标调控研究—— 以河北省卢龙县为例

本文从主体功能区战略角度出发,构建了适用于土地利用总体规划中新增建设用地指标分配的主体功能区划分指标体系,以河北省卢龙县为例,得出该县主体功能区划结果。并结合区域土地利用及土地开发、利用、整治、保护(DUHP)优先度的组合模式,计算在新一轮土地利用总体规划中卢龙县分配到各乡镇的新增建设用地指标。其中刘田各庄镇、卢龙镇和石门镇3个乡镇作为卢龙县优先开发区和重点开发区,分配到的新增建设用地指标最多,均达到230 hm2以上;其他乡镇在保证重点城区发展的基础上,也获得一定数量的指标。本文旨在利用此种方法,为土地利用总体规划的指标分配提供一定的方法支撑,促进规划范围内土地资源优化配置,保证土地资源的可持续利用。

Study on new construction land regulation in land use planning based on major function-oriented zoning

Land use planning lays the critical basis for land macro-control and land use regulation systems.Major function-oriented zoning planning locates state and local development directions and requirements in relation to the land use arrangement and structure in space.This in turn comprehensively promotes state or local economy and coordinates sustainable development.Based on func-tion-oriented zoning strategies,the main function-oriented zoning index systems including the importance of eco-environment,sup-port of social economy and land use strength were structured in this paper.The new construction land index distribution was suitable for the overall land use planning in the study area.The paper analyzed Lulong County of Hebei Province as a case study and used GIS(Geographical Information System) platform to evaluate new construction land area in different village/towns via weighted summation and "matris" with available data.Land development(D),use(U),harness(H) and protection(P) of land use were set different priorities,U-H-D-P,D-U-H-P,H-P-U-D,P-H-U-D,in which the weight of D were 0.256,0.491,0.148 and 0.104 respec-tively.And then new construction land area allocated to each village and town in the overall land use planning in Lulong County were calculated.Among the villages/towns,Liutiangezhuang,Lulong and Shimen were the important priority development towns with the most new construction land area as much as 230 hm2 and more.Other villages and towns also attained the level of indexes needed for development of urban areas.The paper coordinated land use plan and major function-oriented zoning as the breakthrough point.Compared with traditional land use planning,the new planning(based on major function-oriented zoning) to some extent overcame the subjectivity of decision makers and comprehensively coordinated sustainable ideas.The paper provided methodological basis for index distribution of overall land use planning,promoted optimal allocation of regional land resources within program limits and ensured sustainable utilization of land resources.
