摘　　要：基于1996年、2000年、2004年、2008年、2012年和2016年6期遥感影像数据,利用监督分类法和目视解译法提取建设用地信息,采用建成区扩张强度指数、动态度、弹性系数以及速率,定量分析克拉玛依市建成区1996-2016年时序变化,采用分形维数、重心转移及紧凑度,分析其空间分异特征。结果表明:1)在扩展方式上,建成区总体以"团状+内部填充式+星状+沿交通线"扩展模式扩张,各时段扩展方式各异;2)在扩展方向上,呈现"东南-西南-西北"方向转变空间格局,重心迁移符合"三轴两片区"发展规律;3)在扩展驱动因子上,人口规模推动建成区进一步扩张,经济发展水平是最根本的推动力,矿产资源的开发与现代交通是重要因素,政府宏观政策的落实引导建成区扩张,决定城区的规模及格局。对于建成区扩张相对松散、粗放等问题,需要对空间布局进行集约化管制,实现高质量增长。This paper, based on remote sensing data of every four years from 1996 to 2016, uses visual interpretation to extract construction land use information, applies constructed area expansion index, dynamic degree, flexibility coefficient and rate to quantitatively analyze its temporal changes during 1996 to 2016 in Karamay city, and studies its spatial differentiation via fractional dimension, barycenter transfer and compactness. Constructed area expands in forms of "clots, inner filling, star-like and along transportation lines", varying with stages. Expansion direction changes from southeast, southwest to northeast with barycenter transfer consistent with "three-axis-two-district". Population size drives such expansion with economic development as its core pushing force. Mineral resources development and modern transportation are vital factors, directed by governmental macroscopic policies, which determine the size and layout of urbanization. Issues such as loose and primitive constructed expansion need to be resolved through spatial extensive controls in order to reach a quality growth.
