| 摘 要： | 以RS和GIS技术为支撑，基于多时相Landsat遥感数据，辅助1：1万地形图，对平顶山市1992--2012年城市建成区范围进行动态监测，并对其21年来城市空间扩展特征和驱动因素进行分析．结果表明：21年I．q平顶山建成区面积扩大77．61km2，增加了近3．3倍；城区扩展主要体现在东西方向；在政策导向的前提下，其资源分布趋势、社会经济增长和人1：1数量增加是建成区扩展的核心影响因子．

| Abstract: | Based on RS and GIS, the built-up area of Pingdingshan has been changed greatly during the past 21 years from multi-temporal Landsat data. The paper used a time series of Landsat MSS and TM images to extract the change of the built-up area in Pingding Shan from 1992 to 2012,assisted 1：10 000 topographic map. The results show that the built-up area increased by 3.3 times and expanded by about 77.61 km2 dur;ng the past 21 years. And the new areas mainly distribute in the west and east parts of the city. The key driving factor of urban expansion is Resource＇s distribution trend, social economy （GDP） and population growth rate, which are impacted by policy to a great content. |
