摘　　要：遥感图像的多时相特性为城镇扩展动态监测提供了可供定性及定量分析的丰富来源。本文应用2009~2014年的多源高分辨率遥感卫星影像数据对兰州市城镇扩展进行了年度动态遥感监测分析,监测结果表明:兰州市近几年城镇扩展年际变化明显,与人口、经济和政策的驱动作用紧密相关。基于多源高分辨卫星影像进行城镇扩展年度动态监测的方法具有实用性,并且监测频次高、精度高,更具现势性。The character that the multi - temporal remote sense image has provided rich source of information for the qualitative and quantitative analysis for urban expansion dynamic monitoring. In this paper, the remote sensing satellite image data of 2009 -2014 is used to analyze the urban expansion of Lanzhou, the result of monitor show that urban expansion of the inter - annual variation is obvi- ous, and the variation is closely related to population, economy and policy. Based on multi -original and high resolution satellite im- age, the method of annual dynamic monitoring of urban expansion is practical, and the monitor is high frequent, high precision, have a more variety.
