| 摘 要： | 利用累积距平等方法对柴达木盆地近46 a(1961~2006年)气温、降水资料进行了分析,探讨了柴达木盆地气候变化对荒漠化的影响。结果显示:柴达木盆地气候变暖趋势明显,土地沙漠化面积扩大、植被退化、覆盖率减少和盐渍化程度加重。气候变暖、多大风、蒸发强是影响该区土地荒漠化的主要自然原因之一。

| Abstract: | Based on temperature and precipitation data during 1961-2006 of Qaidamu Basin,the influence of climate change on desertification was analyzed using the method of cumulative departure.Results show that climate warming trend there is obvious,and desertification area is increasing,vegetation degradation and soil salinity are severe.The warming climate,frequently heavy wind and ascending evaporation are major natural causes resulting in desertification of Qaidamu Basin. |
