中文摘要：

资源型城市的生产和发展与资源开发密切联系，既有资源开采利用带来的生态环境问题，同时又面临城市化进程加快而出现的城市化问题。利用遥感与GIS结合的方法，分析包头市近10年来土地利用、城市化扩张与植被覆盖度等变化情况。结果显示，包头市近10年来城市化进程加快，建设用地的面积呈现较大扩张态势；建设用地的增加主要以占用草地与耕地等为代价转化而来；包头市总体植被覆盖度随时间推移逐渐减小，但建成区植被覆盖度略有增加，生态环境质量呈现总体下降与局部转好的趋势。

英文摘要：

The development of resource-based city related closely to resources exploitation , which results in ecological and environmental issues , meanwhile , resource-based city also have to face challenges in the direction of urbanization.Using a combination of Remote Sensing （ RS） and Geographic Information System （ GIS） , the land use , urban sprawl and the dynamic of vegetation coverage of Baotou in recent decade have been studied in this paper.The result indicates that：in the past ten years , benefiting from the transformation of grassland and cultivated land , area of construction land had a rapid growth;Vegeta-tion coverage reduced with time overall , but increased in urban area , the actual ecological environment quality has a trend of decreased slightly on the whole and turned good partially.
