摘要
根据2期同一时相TM遥感影像资料,获取土地类型变化信息,分析人类活动对毛乌素沙地沙漠化的影响过程。结果表明,1996~2006年,研究区土地类型发生了很大变化:耕地面积减小,林地和水域面积增加;草地面积减小,沙地面积增加。
Based on TM remote sensing image data of 2 periods in the same phase,the change information of land type was obtained and the influencing course of human activity on the desertification of Maowusu sand land was analyzed.The results showed that between 1996 and 2006,the land type of research area was changed enormously.In detail,the arable area was reduced,the areas of wood land and watershed were increased,the grassland area was reduced and the sand area was increased.
