快速工业化区域建设用地扩张是一个由诸多要素相互偶联的复合系统。文章从规模扩张、空间扩张和景观变迁三个维度,揭示快速工业化区域建设用地扩张的基本特征,并对建设用地扩张的时空演进进行系统阐述。结果表明,在我国改革开放以来的特定制度环境及变迁条件下,伴随工业化和经济社会快速发展进程,快速工业化区域特别是“自下而上”工业化区域建设用地规模扩张先后经历了加速、高速和持续快速三个阶段,空间扩张由相对均衡到非均衡快速发展、再回复到相对均衡,景观聚集度出现先显著下降、后逐步回升态势。文章最后针对快速工业化区域发展实际,提出建设用地扩张调控政策建议。
The expansion of construction land for rapid industrialization is a complex system in which many elements are coupled to each other. From the three dimensions of scale expansion, spatial expansion and landscape change, the article reveals the basic characteristics of the expansion of construction land in the fast industrialized region and systematically expounds the spatio-temporal evolution of construction land expansion. The results show that under the specific institutional environment and changes since China’s reform and opening up, with the rapid development of industrialization and economic society, the rapid expansion of the scale of construction land in the fast industrialized region, especially the “bottom-up” industrialized region, has accelerated. In the three stages of high-speed and sustained rapid growth, the spatial expansion has developed rapidly from relatively equilibrium to non-equilibrium, and has returned to relative equilibrium. The degree of aggregation of landscapes has dropped significantly at first and then gradually rebounded. At the end of the article, in light of the actual development of the rapid industrialized region, the proposed policy for the expansion of land for construction control was proposed.
