【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]:The rapid expansion of construction land and the rapid accumulation of urban population are the important characteristics of the urbanization process in China. The imbalance of human-land space has become an important constraint for the efficient and sustainable development of cities and regions. Taking the West Bank of Taiwan Strait as an example, this paper analyzes the spatial imbalance and evolution characteristics of construction land and urban population by using Gini coefficient, spatial direction coefficient, comparative advantage index and deviation coefficient model. Using OLS and GWR models, the driving mechanism of urban man-land spatial imbalance is discussed. The results of the study show that the main sticking point of the imbalance in the spatial distribution of man and land in urban areas is the rapid expansion of construction land, the imbalance in distribution, and the violent fluctuations. The dominant reason of the imbalance of urban human-land spatial pattern is that the accumulation of construction land to the central city is ahead of the urban population accumulation, which is characterized by regional differentiation and spatial polarization. Along with the urban development, it presents the evolutionary characteristics of "population risking, land risking and human-land coordination" (3) the upgrading and adjustment of industrial structure, the level of land urbanization, Land economic efficiency and urban location difference are important driving factors for spatial imbalance of construction land and urban population. The relevant conclusions can provide a reference for optimizing the allocation of land resources and realizing new urbanization.
