| 摘 要： | 由于各地资源禀赋差异和各级政府之间的复杂关系，城市群交界地区不可避免地存在经济社会发展上的矛盾和不平衡。已有研究揭示了行政边界效应在省域、城市群等不同尺度均普遍存在，且在不同阶段影响土地利用变化的程度大小不一，但多将行政边界转化为虚拟变量而非空间地理要素，不足以理解中微观尺度各种因素之间的复杂相互作用。论文旨在利用1985—2020年的中国年度土地覆盖数据集，以区县为单元，运用质心迁移、核密度分析和Logistic回归方法，分析京津冀典型城市群交界地区“通州—武清—廊坊(通武廊)地区”不透水面(ISA)的扩张机理并测度行政边界效应的影响。结果显示：(1)不同行政区因资源禀赋和所处发展阶段的不同，城市用地扩张的速度和主要时期存在一定的差异；(2)由于要素的高度流动，地理邻近的行政区城市扩张驱动要素表现出一定的相似性；(3)在不同区域分工水平下，行政界线的边界效应对城市用地扩张的影响表现出一定差异性。通过“强—弱”管控提高通武廊地区各要素协调水平，减少行政边界对地方之间资源整合的负面影响，对于实现京津冀城市群协同发展具有重要作用。

| Abstract: | Due to the differences in resource endowments and the complex relationship between governments at all levels, there are inevitable conflicts and imbalances in socialeco development in the cross-boundary regions of urban agglomerations. Scholars have revealed that the administrative boundary effect is common in different scales such as provincial and urban agglomeration, and its influence on land use change varies in different development stages. However, previous studies have mostly transformed administrative boundaries into virtual variables rather than as spatial geographical elements, which is insufficient for understanding the complex interactions between various factors at the meso and micro scales. This study analyzed the expansion mechanism of impervious surface area (ISA) in Tongzhou-Wuqing-Langfang (TWL)—a typical cross-boundary region of the Beijing-Tianjin-Hebei urban agglomeration—by using China's Land-Use/Cover Datasets from 1985 to 2020. Taking districts and counties as the units of analysis, we used centroid migration, kernel density analysis, and Logistic regression methods to measure the impact of administrative boundaries. The results show that: 1) The speed and main period of urban land expansion in different administrative regions varied due to different resource endowments and development stages. 2) Due to the high mobility of factors, the driving forces of urban expansion in geographically adjacent administrative regions showed some similarities. 3) Under different levels of regional collaboration, the influence of the administrative boundaries on urban land expansion also varied. Improving the coordination level of various elements in the TWL area through "strong-weak" control and reducing the negative impact of administrative boundaries on local resource integration play an important role in realizing the coordinated development of the Beijing-Tianjin-Hebei urban agglomeration. |
