中文摘要	以国家林业局库姆塔格荒漠生态系统定位研究站2012-2013年的气象资料为依据,分析了库姆塔格沙漠东缘荒漠-绿洲过渡带的风况特征和输沙势变化情况。结果表明: 1)研究区主要受WNW-NW和 ENE-NE 两组风向起沙风控制,其中主风向为WNW-NW,占全年起沙风的35. 15%,次风向为ENE-NE,占全年起沙风的24. 80%; 2)该区起沙风主要发生在春季和夏季,占全年起沙风的72. 59%,春季起沙风主风向为 ENE,其他季节起沙风的主风向为WNW 方向。3)在风沙活动期内,年合成输沙势(RDP)为54. 73VU,合成输沙势方向(DDR)为S 189°,研究区属于低风能环境。研究区输沙势的大小具有明显的季节性,其中春季和夏季具有较高的总输沙势(DP)和合成输沙势(DDR)。
英文摘要	The desert-oasis ecotone in the eastern marginal zone of the Kumtag Desert is one of the areas with the severest desertification in China. In this study a statistical analysis on wind regime and resultant sand-transporting potential from 2012 to 2013in the eastern marginal zone of the Kumtag Desert was carried out. The results showed that: (1)This region was affected predominantly by WNW-NW和ENE-NE wind directions,there was a higher accumulated frequency with 35.15% in the WNW-NW direction,and the frequency of sand-moving wind in the ENE-NE was 24. 8%; (2)Sand-moving wind in the study area occurred mainly in the spring and summer,its occurring frequency was 72. 59%,the prevailing wind in spring was ENE,and WNW in other seasons; (3)During the phase of wind-sand activity,resultant sand-transporting potential(RDP)was 54. 73VU,resultant sand-transporting directon (RDD)was 189°S. There was a higher sand-transporting potential(RDP)and drift potential(DP)in the spring and summer.
