城市化是一个复杂的空间现象，涉及土地利用的重要组成和相互作用。然而，只有少数研究定量研究了多维的城市土地利用模式与土地利用政策的见解，特别是在中国的快速城市化进程的背景下。采用空间熵和差异指数等多源数据，结合元胞自动机（CA）模型和结构方程模型（SEM），对中国城市土地利用格局进行研究。结果表明，中国土地利用格局呈现出混合程度较高（北京、上海）、分离程度较低（襄阳、唐山、贵阳）和分离程度较高（重庆）的特点，并可分为经济主导型、政府主导型和地域限制型3种典型类型。研究结果还表明，居民部门与GDP和城市建成区面积相关;公共部门由GDP、城市建成区面积和铺装道路面积驱动;商业部门与GDP和铺装道路面积相关。土地利用模式不仅受经济因素的影响，而且还受制于中国基于其独特的社会政治特征而制定的土地政策。揭示了中国城市化的复杂空间特征，政府在促进土地利用配置方面仍然发挥着重要作用。该研究为理解新型城镇化背景下土地利用格局重构的土地利用政策提供了思路。
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.
