摘要(Abstract):
针对塔里木河流域脆弱的生态环境,该文采用地理信息系统、遥感技术手段提取2000年、2006年、2009年、2012年以及2014年塔里木河流域地表覆盖分类数据并对其变化特征进行分析。结果表明:2000—2014年塔里木河流域除水域、荒漠与裸露地表面积减少外,其余地表类型均呈增加趋势,其中变化量最大的为荒漠与裸露地表、冰川与积雪、耕地、草地,其变化量分别为-34 558.1km~2、14 351.15km~2、6 471.79km~2、6 383.94km~2。2000—2014年塔里木河流域荒漠与裸露地表面积减小,主要转变为了草地、林地与耕地;耕地面积增加主要来自于林地、草地、荒漠与裸露地表;冰川和积雪的面积增加主要增加来源为林地、草地和荒漠与裸露地表。
