摘　　要：以遥感影像为数据源,借助GIS技术提取了4个时期的郑州市建成区的面积信息,利用扩展强度系数、紧凑度指数、分维数指数、城市面积-人口弹性系数等参数,从扩展数量、形态、扩展合理性3个方面分析了郑州1999—2007年建成区扩展的时空特征以及与人口增长之间的协调关系.结果表明:从1999—2007年8年间,郑州市建成区面积净增了211.802 km2,平均每年扩展26.475 km2,扩展强度指数为27.222%,城市空间形态越来越离散,高速外延式扩展是建成区用地扩展的主要特征,城市用地扩张与人口增长不相适宜.The expansion of Zhengzhou urban area in the period from 1999 to 2007 was obtained by using remote sensing images.The spatial-temporal features of the urban expansion and the relationship between urban expansion and population growth in the period were analyzed by using some indexes on three aspects of quanity,shape, and rationality.The research shows that the built-up area has increased 211.802 km2,extend velocity is 26.475 km2,and extend intension is 27.222% in the period. The urban space shape becomes more and more scatter.The important feature of Zhengzhou urban expansion is the high speed extension outside pattern.The urban sprawl rate of Zhengzhou did not match urban population growth during the study years.
