基于引力模型的厦漳泉大都市区城市空间结构研究

Spatial Patterns of Xia-Zhang-Quan Metropolis Based on Gravity Model

空间相互作用力和空间分布轴线是决定城市空间结构的核心要素。利用引力模型和断裂点公式分析厦漳泉大都市区的空间结构特征,研究结果发现:环泉州湾和厦门市已成为两大增长极,漳州市区和南安市则是重要的增长点,该大都市区核心区呈"J"字型发展;由于各县市间的锁定效应与屏蔽效应,城市发展偏心化严重。因此,厦漳泉大都市区不仅要注重其"J"字型发展轴,也要强调多中心理念,规避屏蔽效应,降低空间不平衡性。

Spatial interaction and spatial axes are the key factors to determine urban spatial structure. Using the gravity model and breaking point formula to measure and analyze the spatial structure of Xia-Zhang-Quan metropolis. The results show that Xiamen City and Quanzhou-bay Area have become two growth pole of Xia-ZhangQuan metropolis,and Zhangzhou and Nanan City become important growth point,which make the spatial axes of metropolis shape as ＂J＂. In addition,due to locking effect and shielding effect,the city becomes biased-growth.Therefore,to build Xia-Zhang-Quan metropolis,not only the ＂J＂axis should be pay more attention to,but also multi-centre city concept should be stress,shielding effect should be avoid,which aim to reduce spatial imbalance.
