建设用地集约利用是一个动态提升的过程,深刻认识其过程性内涵、特征及变量关系,对于创新建设用地集约利用评价的理论与方法研究具有重要意义。本文基于“五量”协同概念模型,界定了建设用地集约利用的内涵,构建了“总量规模(T)、增量效应(I)、质量弹性(Q)、存量潜力(S)、流量效率(F)”五位一体的建设用地集约利用评价指标体系和多因素加权求和、多边形面积求算与障碍因子诊断的综合测法,通过山东省17地市实证分析,提出了区域建设用地集约利用“五量”协同调控方法与对策。结果显示:①山东省建设用地集约利用的T、I、Q、S、F分值整体差异显著,变异系数分别为19.81%、18.23%、21.13%、20.84%和16.78%,但空间分布具有一定的局地相似性;②建设用地综合集约度分值为2.05~7.77,对应“五量”分值的协调性逐渐提升,但“极值互补”集簇现象更为明显;⑧建设用地集约利用的“五量”障碍因子具有较强的区域主导性和相似性,在总量规模和增量效应方面表现为单因子强势影响,在质量弹性、存量潜力和流量效率方面则表现为双因子均衡影响;④山东省建设用地集约利用水平提升的核心在于有效控制建设用地总量和增量规模,应沿着存量优化、减量增效和质量提升的路径,逐渐降低年度增量计划,实现规划总量控制的目标。
Construction land intensive use is understanding of its procedural connotation significance to the research methods used in a dynamic process of gradual development. The deep and the relationship between variables has important construction land intensive use evaluation. We define the meaning of construction land intensive use based on the five-variables collaboration model, construct an evaluation index system of construction land intensive use materialized in such five aspects (total scale, incremental effect, quality elasticity, stock potential and flux efficiency; the TIQSF indicator system)and include multivariate weighted summation, polygon areas and obstacle factor diagnosis. Through actual attests and analyses of 17 cities in Shandong we propose the five- variables collaborative controlling method and countermeasures of regional construction land intensive use. We found that the T, I, Q, S and F scores showed obvious diversity and the variable coefficients were 19.81%, 18.23%, 21.13%, 20.84% and 16.78%; the spatial distribution also had certain local similarity. The comprehensive scores were 2.05-7.77, the coordination of T, I, Q, S and F scores gradually improved from low to high, but the concentrated distribution phenomenon was obvious. The dominant obstacle factors in different regions were significant: T1, T2, L and I2 showed single factor strong effects; Q1, Q2, S1, S2, F1 and F3 showed double factor equilibrium effects. Effective control of the total and incremental scale of construction land was key to enhancing the level of construction land intensive use in Shandong. Shandong should reduce the increment of construction land in annual planning to control the scale of construction land plan along paths, including reducing the quantity, heightening the effect and improving quality.
