| 摘 要： | 土地利用与土地覆盖变化(LUCC)研究是全球环境变化研究的一个重要方面,也是地理学综合研究的国际性前沿课题。基于多时相的TM影像数据,从流域尺度研究巢湖流域的土地利用/覆盖变化,分析探讨了土地利用变化的社会经济驱动力。研究结果表明:1979～2008年间巢湖流域的土地利用发生了比较明显的变化,主要表现在耕地锐减和建设用地激增;经济发展、城镇化、工业化、人口增加是造成巢湖流域土地利用变化的主要驱动力。

| Abstract: | The study of land use and land cover change(LUCC) is one of the most important aspects of global change,and also the international forefront of comprehensive research in geography.Based on TM data,this paper studies the structure change of land use and its driving forces in Chaohu Lake Basin during the past 30 years.The result shows that there has been a significant change of land use in Chaohu Lake Basin,i.e.,cropland reducing and build-up land increasing;.Also,the economic hi-speed growth,urbanize,industr... |
