过去二十年，中国经历了快速而大规模的城市化和工业化。尽管据报道在地方和区域尺度上进行了大量研究，但在国家层面上对这两个相互交织过程的轨迹、模式和驱动因素的报道却很少。这主要是由于直到最近，在国家层面上还没有土地利用和土地覆盖变化的高分辨率空间数据。本文报道的研究旨在填补这一知识空白。利用中国土地利用/覆被变化数据库（CLUD），以1990 - 2010年为间隔，对这两个相互交织的过程进行了分析，以确定它们的发展轨迹、时空格局和驱动力。我们的主要发现包括：(1)全国城市和工业用地面积从1990年的4.85 × 10(4) km(2)增加到2010年的9.08 × 10(4) km(2)；(2)与20世纪90年代相比，2000年代城市用地和工业用地的扩张率分别增长了2.15倍和5.79倍；③区域间扩张速度差异显著，呈现出沿海最快、东北最慢的空间格局；④国家发展战略和区域土地利用政策对土地扩张的影响显著；(5)社会经济因素以及地方和区域土地利用政策解释了区域差异。(C) 2015 Elsevier B.V.版权所有
The past two decades saw rapid and massive urbanization and industrialization in China. Despite much research has been reportedly done at local and regional scales, little has been reported on the trajectories, patterns, and drivers of these two intertwining processes at the national level. This is mainly due to the fact that until recently, high resolution spatial data of land use and land cover change were not available at national level. The research reported in this paper aimed to fill this knowledge gap. Employing the China Land Use/Cover Dataset (CLUD), a national land use/cover change database our research team developed over the past decade, we analyzed the two intertwining processes at a 5 year interval from 1990 to 2010 to identify their trajectories, spatiotemporal patterns, and driving forces. Among out key findings are that (1) the nation's urban and industrial land areas increased from 4.85 x 10(4) km(2) in 1990 to 9.08 x 10(4) km(2) in 2010; (2) compared to those in the 1990s, the expansion rates of urban land and industrial land in the 2000s were respectively 2.15 and 5.79 times higher; (3) the expansion rates varied significantly across regions, revealing a distinctive spatial pattern with coastal regions being the fastest and the northeastern the slowest; (4) national development strategies and regional land-use policies had prominent impacts on land expansions; while (5) socioeconomic factors along with local and regional land-use policies explained the regional variations.
