基于RS和GIS等技术手段，采集开封市不同时段的遥感影像，采用监督分类和非监督分类等方法，通过提取城市建成区边界，进行城市扩展分析。结合统计学方法，辅以城市扩张强度指标，研究开封市城市变化的数量特征和空间特征，即定量分析其空间动态扩张趋势。通过分析社会、经济、环境、人口、政策等多种因素，研究城市扩展的驱动力，以及城市动态变化所产生的影响。

Based on RS and GIS and other technical means, this paper collects remote sensing images of Kaifeng at different periods, and adopts methods of supervised classification and unsupervised classification to analyze urban expansion by means of extracting the urban built-up area boundary. Combined with statistical methods and accompanied by urban expansion intensity index, it researchs the quantity feature and spatial feature of changes in Kaifeng city. By analyzing the various affecting factors such as the society, economy, environment, population and policy and so on, this paper studys the driving force of urban expansion, as well as the influence produced due to the city dynamic changes.
