摘要

基于RS和GIS技术

对1990-2010年艾比湖地区沙漠化动态变化进行了监测。研究表明

艾比湖地区分布着大面积的沙漠化土地

主要分布在其东部和西岸地区。20 a间沙漠化土地面积明显减少

沙漠化土地面积从1990年的4426.49 km

减少到2010年的637.33 km

减少了3789.16 km

。经历了强烈逆转-稳定发展-基本稳定3个阶段

1990-2001年沙漠化土地面积从4426.49 km

减少到3713.25 km

;2001-2007年沙漠化土地总面积保持基本不变

但沙漠化程度稍有加重;2007-2010年沙漠化土地总面积略微增加

沙漠化程度在持续加深。近20 a来沙漠化转变尤为显著

气候变化和不合理的人类活动共同导致了研究区东部的沙漠化程度的加剧。

Abstract

The distribution of desertification land in Ebinur Lake region in 1990 and 2010 was monitored by remote sensing and GIS technology. There was a large area of desertification land in Ebinur Lake region and it was mainly distributed in east of study area and the west bank of Ebinur Lake. The decrease of desertification land was obvious from 1990 to 2010. The desertification land decreased from 4426.49 km2 in 1990 to 3789.16 km2 in 2010

decreased by 3789.16 km2. The study area experienced a development process from strong reverse of desertification to stability and development. From 1990 to 2001

the area of desertified land reduced from 4426.49 km2 to 3713.25 km2; from 2001 to 2007

the total area of desertified land will remain basically unchanged

but the degree of desertification is slightly higier. In the past 20 years

the desertification is particularly serious due to climate change and irrational human activities

and the eastern part of the study area is more serious.
