塔里木河下游绿洲的沙漠化灾害现状及其原因探讨

截至2000年塔里木河下游沙漠化土地面积超过土地总面积的90%,其中重度沙漠化土地面积为756.02 km2,占整个下游土地面积的52.71%,随着沙漠化的加剧,该地区的交通运输、居民的生活受到了极大的威胁,大片耕地被迫弃耕。2007年11月上旬对塔里木河下游地区进行了野外考察。根据实地考察收集和前人研究的资料基础上,对塔里木河下游绿洲的沙漠化灾害的现状及其成因进行探讨。

Desertification Disasters and Its Control Countermeasures in the Oasis of the Lower Reaches of Tarim River

By 2002,desertification land area was 90% more than that of the total area,of which the area of severe desertification land was 756.02 km2,which takes 52.71% of land area in the lower reaches of Tarim River.With the aggravating of the desertification,the local communication and transportation and the daily life of the residents are threatened seriously,and large areas of farmland are forced to abandon. On December 2007,the authors went to the lower reaches of the Tarim River for field investigation.This paper discusses the current situation of desertification disaster and disaster reduction countermeasures of the Lower reaches of Tarim River on the basis of previous studies and field survey.
