摘要:

建设用地剧烈扩张和城市人口快速聚集是中国城镇化进程的重要特征,人地空间失调已成为城市和区域高效、可持续发展的重要制约。本文以城镇化快速推进中的台湾海峡西岸地区为案例,采用基尼系数、空间指向系数、比较优势指数和离差系数模型分析了建设用地和城市人口的空间失调和演化特征,使用OLS和GWR模型探讨了城市人地空间失调的驱动机制。研究结果表明:①城市人地空间分布失调的主要症结是建设用地扩张速度快、分布失衡、波动剧烈,并具有先扩大后缩小的动态特征;②城市人地空间格局失调的主导症结是建设用地向中心城市的聚集超前于城市人口聚集,表现为区域分异和空间极化特征,并伴随城市发展呈现“人口冒进-土地冒进-人地协调”的演化特征;③产业结构升级调整、土地城镇化水平、土地的经济效率和城市区位差异是建设用地和城市人口空间失调的重要驱动因素。相关结论可为优化土地资源配置、实现新型城镇化提供参考。

Abstract:

Construction land expansion and urban population aggregation are two critical and interactive processes during urbanization. The spatial imbalance between them has become a constraint of healthy urbanization. This study analyzed the characteristics of the spatial imbalance between construction land and the urban population on the West Coast of the Taiwan Strait Area,using spatial distribution index,comparative advantage index,and deviation coefficient modeling. Driving forces of the spatial imbalance were explored based on OLS and GWR models. We found that the main sticking points driving the spatial imbalance between construction land and the urban population were spatial sprawl,uneven distribution and violent fluctuation of construction land. The imbalanced spatial distribution has experienced a phased process,and the gap expanded at first and then narrowed. Construction land shows significant central city oriented spatial aggregation,and spatial aggregation far outstripped spatial aggregation of the urban population. This spatial imbalance exhibited significant regional differences and a spatial polarization pattern,and was closely related to city development. Along with city development,the imbalance evolved from aggressive expansion of construction land to aggressive aggregation of urban population and eventually to the balance of spatial patterns. Changes in industrial structure,land urbanization level,economic efficiency of land and geographical positions were identified as main driving forces of the spatial imbalance between construction land and urban populations. These findings will help optimize the allocation of land resources,and facilitate implementation of new urbanization.
