摘　　要：以郑州市下辖且接壤的巩义市为研究对象,以1990年和2020年两期TM/OLI影像和统计年鉴数据为依据,使用1 km×1 km网格划分样区并提取各样区的综合土地利用动态度数值,借助数学模型分析确定城市边缘区范围,分析巩义市近30年来城市边缘区用地变化特征及扩展机制。结果表明,自然条件是用地扩张的基础因素,政策与经济是边缘区外扩的核心驱动力,交通对扩张具有指向性作用;边缘区内的土地变化主要表现为建设用地急剧增加、农业用地锐减,同时受距离和开发时序影响,用地类型交错复杂,破碎化特征明显。Based on the TM/OLI images and statistical yearbook data in 1990 and 2020,this paper used the 1 km×1 km grid to divide the sample areas and extract the comprehensive land use dynamic values of each area,and determined the scope of urban fringe areas with the help of mathematical model analysis,and then analyzed the land use change characteristics and expansion mechanism of urban fringe areas in Gongyi City in the past 30 years.The results showed that natural conditions were the basic factors for land use expansion,policies and economy were the core driving forces for the expansion of fringe areas,and transportation had a directive role in the expansion;the land change in the fringe area was mainly characterized by a sharp increase in construction land and a sharp decrease in agricultural land,as well as by the influence of distance and development time sequence,with interlocking and complex land types and obvious fragmentation characteristics.
