Abstract: Based on the 2000 and 2010 land cover classification of China’s 30 m GLC data product (GlobeLand30), the construction land use data was extracted. This study evaluates the spatial pattern and change of construction land use from 2000 to 2010. A comprehensive method was used including spatial auto correlation, statistical analysis, land transformation model, and landscape index. The study seeks to provide guidance for the sustainable development of Beijing-Tianjin-Hebei metropolitan. The main conclusions are as follows: the construction land of Beijing-Tianjin-Hebei metropolitan has experienced increasing rapidly, and Beijing city, Tianjin city and Shijiazhuang city have been the three construction land high density cores. The high density counties expand along the three principal axis of Beijing-Baoding-Shijiazhuang, Beijing-Tianjin, and Tangshan-Tianjin-Cangzhou. The highest growth counties distribute intensively in the Beijing-Tianjin-Tangshan region, especially the suburban districts of Beijing city, Tianjin city and Tangshan city. The results confirm the predominance of construction land expansion primarily over cultivated land, and the highest rate of crop land occupancy area mainly focused on the surrounding counties of Beijing city, Tianjin city and Tangshan city. The changes of the construction land patches in almost each district has extensive and disorder. The force of construction land use changes in Beijing-Tianjin-Hebei metropolitan is still the expansion of urban land and rural settlement land, undoubtedly affected by population and economic development, which is mainly in the population increasing, GDP, and fixed investments.

摘要： 基于2000、2010年京津冀都市圈30 m分辨率的地表覆盖数据，提取出建设用地数据信息，运用空间统计分析、空间自相关、土地类型转换及景观指标测算的方法，从规模变化、空间变化和景观格局变化的角度，揭示京津冀都市圈建设用地的空间格局及时空变化特征，并通过多元回归模型对影响建设用地变化的驱动因素进行分析。结果表明：2000-2010年间，在京津冀一体化发展战略背景下，伴随产业升级与产业转移的快速发展，京津冀都市圈建设用地规模经历了快速增长，高密度区县数量及其空间集聚性均呈显著上升趋势；空间变化的非均衡性和两极分化特征明显，整体沿北京—保定—石家庄、北京—天津、唐山—天津—沧州三条轴线扩展，同时京津唐地区的组团扩张和网络扩张特征日趋明显，呈现“中心—外围—边缘”的圈层式结构；景观格局的空间分散态势有所增加，各区县建设用地紧凑度指数较低，变化程度较小，建设用地的斑块变化具有一定的粗放性和无序性。运用多元回归对建设用地变化的驱动因素进行分析发现，人口、GDP和固定资产投资是影响京津冀都市圈建设用地的主导因素，其中人口是影响两期建设用地扩展的主导因素。
