刈割是策勒绿洲-荒漠过渡带疏叶骆驼刺(Alhagi sparsifolia)利用最主要的方式之一。对疏叶骆驼刺刈割干扰4年后植被的恢复能力、阻沙能力和土壤性质进行了研究。结果表明:秋季刈割下的植被恢复能力和阻沙能力都强于春季刈割;与对照相比,春季刈割和秋季刈割都使表层土壤容重下降,秋季刈割下表层土壤孔隙度比春季刈割下提高了2.5%;秋季刈割和春季刈割使灌丛下表层土壤有机质、全氮都增加,而全磷、全钾没有明显的影响;相比较而言,刈割4年以后秋季刈割更容易形成"肥岛",更加有利于荒漠草地生态系统功能的恢复。

采用1987、1999年和2008年3期TM卫星数据,对额济纳绿洲2000年黑河分水前后土地覆被变化进行了研究,并分析了额济纳绿洲土地覆被变化的驱动因素。结果表明:(1)从不同覆盖等级的面积变化来看,额济纳绿洲的主体是中植被覆盖区。1987—1999年额济纳绿洲的植被呈退化趋势。2000年黑河分水后至2008年,额济纳绿洲植被退化的趋势已得到缓解。(2)从不同土地利用类型的面积变化来看,额济纳绿洲
