摘    要:基于柴达木盆地1959-2004年土地沙漠化的6次动态监测结果,对该区土地沙化现状进行了分析研究.分析结果表明,盆地沙化土地面积从1959年的5.80×106hm2增加到1994年的1.03×107hm2,年增长率为2.13%;随着林业生态工程的实施,1994年以后沙化面积呈现下降趋势,从1994年的1.03×107hm2减少到2004年的9.50×106hm2,年下降率为0.67%;分析结果同时表明,严重和中度沙化面积之和占整个盆地沙化面积的比例从1959年的89.6%上升到2004年的94.1%,占整个盆地土地面积的比例从1959年的23.2%上升到2004年的38.0%,说明局部地区沙化仍在加剧和扩展.进一步探究了造成柴达木盆地土地沙漠化现状的自然因素和主要人为因素,结合监测结果以及沙产业理论,提出了柴达木盆地土地沙漠化防治的具体措施和对策.

关 键 词:柴达木盆地  土地沙化  治理对策  沙产业

Abstract:This study was based on dynamic measurement of deserted land in Chaidamu Basin,Qinghai Province,from 1959 to 2004.Results showed that the area of deserted land in the basin increased from 5800000hm2 in 1959 to 10254000hm2 in 1994,with an increased percentage of 2.13% per year on average.With the implementation of forest policies,the area of deserted land in the basin descended from 10254000hm2 in 1994 to 9495000hm2 in 2004,with a yearly-dropping percentage of 0.67%.The trend of desertification is still aggravated in some regions.The main factors for the expansion of deserted land were studied as well.Finally,some prevention countermeasures were proposed on the basis of the above study and analysis.
Keywords:Chaidamu Basin  land desertification  countermeasure  sand industry
