| 摘 要： | 锡林郭勒盟沙尘暴分布与气象因子和下垫面性质有关,沙尘暴西多东少的分布特征,与大风西多东少、降水西北少东南多、温度西南高东北低的分布特征基本相似;大风是沙尘暴的主要动力因子,温度是产生沙尘暴的热力因素,降水和下垫面性质决定了沙尘暴产生的环境条件。沙尘暴日数随着大风日数与温度增加(升高)而增多;随降水增加而减少;下垫面要素中的地形、地貌为沙尘暴的发生提供沙源、起沙条件;土壤成分自西北向东南为棕钙土带、栗钙土带、黑钙土带、灰色森林土带,植被覆盖度依次增加,沙尘暴分布也依次减少。 |

| Abstract: | The sand-dust storm in Xilin Gol League was in connection with meteorological factor and the underlying surface properties.The distribution characteristics of sandstorm in the west was more than that in the east and it was similar to that there was more wind in the west than that in the east,more precipitation in the southeast than that in the northwest,and higher temperature in the southwest than that in the northeast.So the heavy wind was the main dynamic factor of the formation of the sand-dust storm,the... |
