引 言
城市化是一个复杂的空间现象,涉及土地利用的构成和相互作用。然而,目前只有少数研究定量审查多层面城市土地利用模式,并对土地使用政策有深入认识。Wei Lang, Ying Long, Tingting Chen利用多元数据通过多种计算方法研究中国城市土地利用模式。研究方法包括空间区位熵、差异指数的计算,元胞自动机建模和结构方程模型的结合。该研究既揭示了中国土地利用模式,又为中国新型城镇化建设规划和管理背景下的土地利用政策提供依据和参考。感兴趣的你快来一起学习吧!(全文链接见“阅读原文”)
Rediscovering Chinese cities through the lens of land-use patterns
Wei Lang, Ying Long, Tingting Chen
ABSTRACT:
Urbanization is a complex spatial phenomenon involving significant compositions and interactions in land use. Yet, only few studies have quantitatively examined multidimensional urban land-use patterns with insights into land use policy, particularly in the context of China’s rapid urbanization process. This paper aims to investigate the urban land-use patterns in China by employing multiple measurements with multi-sourced data, including Spatial Entropy and Dissimilarity Index, and a combination of cellular-automata (CA) modeling and Structural Equation Modeling (SEM). The results show that land-use patterns in China are characterized from more mixed (Beijing, Shanghai) to less segregated (Xiangyang, Tangshan, and Guiyang), and the most segregated (Chongqing), which can be categorized into three typical types: economically led, government led, and geographically constrained. The findings also indicate that residential sector has correlation with GDP and urban built-up area; public sector is driven by GDP, urban built-up area, and paved road area; and commercial sector is related to GDP and paved road area. Furthermore, land-use patterns are not only determined by economic forces, but also subject to China’s land policies that formulated based on its unique social and political characteristics. It reveals the complex spatial characterization of urbanization in China, where government still plays an important role in facilitating the land use allocation. The research sheds light on understanding land use policy for land-use patterns reconfiguration in the context of New-Type Urbanization towards better planning and governance.
