| 摘 要： | 利用近43年气象观测资料,分析得出浑善达克沙地气温在逐年升高,而降水量、蒸发量、平均风速、大风日数、沙尘暴日数总体呈逐年减少态势。其中温度升高、降水减少和极端气候事件的增多加剧了浑善达克沙地沙漠化的发展;平均风速逐年减少对该地区沙漠化治理有利。但进入本世纪以后,蒸发量、大风日数和沙尘暴日数有增加趋势,同时通过1976、1987和2002年的遥感卫星监测结果验证:流动沙地面积不断增加,进一步表明浑善达克沙地的沙漠化局部正在扩展,这与该地区气候的变化有关。

| Abstract: | Based on the meteorological observation data in the last 43 years,the increasing of temperature,and the decreasing of precipitation,evaporation,mean velocity,gal and dust storm days in Onqin Daga sandland was pointed out.The increasing of the mean temperature and extreme climate incidents,as well as the decreasing of precipitation intensify the desertification,meanwhile,the decreasing of velocity is advantageous for defending desertification in Onqin Daga sandland.But the evaporation,gale and dust storm days have increasing trend after 2000,and we found that the area of the moving sand is enlarging in Onqin Daga sandland by analyzing the satellite sounding monitoring information in 1976,1987,and 2002.This demonstrates that the development of desertification has close relationship with climatic change. |
