我们研究了美国在多大程度上。S.城市发展是无序扩张的，是什么决定了空间扩张的差异。利用遥感数据跟踪87亿个30 × 30米网格上土地利用的演变，我们测量了平均城市住宅周围未开发土地的数量。在1976年至1992年期间，无计划扩张的程度大致保持不变，尽管各大都市地区的情况差异很大。地下水的可用性，温带气候，崎岖的地形，分散的就业，早期的公共交通基础设施，大都市发展的不确定性，以及城市边缘的未合并土地都增加了蔓延。
We study the extent to which U. S. urban development is sprawling and what determines differences in sprawl across space. Using remote-sensing data to track the evolution of land use on a grid of 8.7 billion 30 X 30 meter cells, we measure sprawl as the amount of undeveloped land surrounding an average urban dwelling. The extent of sprawl remained roughly unchanged between 1976 and 1992, although it varied dramatically across metropolitan areas. Ground water availability, temperate climate, rugged terrain, decentralized employment, early public transport infrastructure, uncertainty about metropolitan growth, and unincorporated land in the urban fringe all increase sprawl.
