随着现代城市空间扩张和功能多元化，多中心兴起，单中心城市模型对城市空间结构的预测能力受到挑战。为了克服该模型在解释当代城市方面的不足，本研究以中国海口市为实证案例，开发了一个综合城市模型，通过结合多个单中心城市模型来描述城市空间结构，这是分析城市空间的基本单元。并通过容积率测算和地理加权回归的方法，反过来检验了该一体化城市模型在海口的适用性。研究结果表明，近几十年来，海口作为省会城市生产活动集中在市中心的传统空间结构受到了沿海新兴旅游功能的挑战。与长期以来围绕城市中心的单中心“城市”模式对城市空间结构产生较强的、不对称的、分布不均的边际效应相比，新发展的沿海单中心“城市”模式对其城市空间结构的边际影响较弱、片面、分布均匀。因此，海口市现有的空间结构可以用一个综合城市模型来描述，该模型由两个基于不同“中心”、城市功能各异的单中心“城市”模型组成。从这个意义上说，这种在单中心城市模型上发展起来的综合城市模型将具有包容性和可扩展性，以分析多中心城市的动态空间结构。
The monocentric city model has been challenged for its predictive power in urban spatial structure as multiple centers rise from the spatial expansion and functional diversification of modern cities. To overcome the deficiency of the model in explaining contemporary cities, this study takes Haikou City in China as an empirical case to develop an integrated city model that depicts the urban spatial structure by combining multiple monocentric city models, the basic unit in analyzing an urban space. The applicability of this integrated city model in Haikou is also examined in return by using the measure of floor area ratio and the method of geographical weighted regression. Results show that the traditional spatial structure of Haikou as a provincial capital where production activities are concentrated in the city center has been challenged by the emerging tourism function along the sea coast over the past decades. Compared with the long-existing monocentric “city” model around the city center that exerts a strong, asymmetrical, and unevenly distributed marginal effect on the urban space, the newly developed monocentric “city” model along the coast has a weak, one-sided, and evenly distributed marginal impact on its urban spatial structure. Therefore, the current spatial structure of Haikou City can be depicted by an integrated city model composed of two monocentric “city” models based on different “centers” with distinct urban functions. In this sense, this integrated city model developed on the monocentric city model will be inclusive and extendable to the analysis of the dynamic spatial structure of a multi-center city.
