摘要: 基于对20世纪80年代、90年代和2002年3期陆地卫星影像的解译,通过统计计算和对比分析方法,研究了浑善达克沙地20多年来植被和土地覆盖的变化情况。结果表明,浑善达克沙地内部植被退化总趋势明显,东、西部各形成了一个植被重度受损区;由于沙地周边的湿地和灌木丛环、沙地内部湿地形成的网状结构对沙地的扩张有一定的抑制作用,同时人类活动的强度和作用时间还比较有限,而且现在的气候不像沙地形成时那样恶劣,虽然沙地内部植被发生退化,但沙地总体范围保持相对稳定;近年来沙地退化趋势受到一定的抑制,主要得益于生态建设工程的实施和禁牧封育等措施。另外,对沙地的保护与利用进行了探讨,提出了有参考价值的建议。

Abstract: The remote sensing images in 1980s, 1990s and 2002 were interpreted to study the dynamics of land cover in Hushandake Sandland by methods of statistics and comparison. It was disclosed that (1) there is a evident degrading tendency of land cover in Hushandake Sandland, and there are two seriously damaged regions distributed respectively in the eastern and western parts of Hushandake Sandland; (2) the boundary of Hushandake Sandland havent extended evidently because there are wetland and bush circles around the sandland, and human activity is not strong enough to make such change, as well as the present climate is better than that at the time the sandland being formed; (3) the desertification tendency of Hushandake Sandland has been controlled at some degree in recent years.

Key words: Hunshandake Sandland, remote sensing, vegetation, desertification, dynamics
