The results showed that in past 20 years,the desertified land in Baxiantong,where the desertification process was mainly affected by human activities,had a greater change extent,which represented in the transformation from mobile and semi-fixed sands to fixed sands and from fixed sands to cropland and woodland.
结果表明:近20年来,以人为活动干扰为主的区域(八仙筒镇),沙漠化土地变化幅度较大,各种沙漠化土地的转化主要表现在沙漠化土地中流动和半固定沙地向固定沙地转化、固定沙地向农田和林地转化;以自然干扰为主的区域(苇莲苏乡),沙漠化土地变化幅度较小,主要表现为各种沙地类型之间的转换;在人为活动为主的区域固定沙地的空间格局变化显著,1985—1995年固定沙地的联合度降低,人为活动干扰较强,而1995—2005年联合度增高,人为活动干扰相对较弱;在自然干扰为主的区域,同一时期空间格局的变化明显的是流动沙地,在1985—1995年,流动沙地斑块破碎度减小,流动沙地发育显著,在1995—2005年,流动沙地的破碎度继续减小,但其面积得到控制,表明治沙效果在这一时期是显著的。
