摘要:

通过风资料的统计和计算,对博斯腾湖流域风沙活动强度环境特征进行了系统的研究。结果表明:博斯腾湖流域年平均风速较小,一般1.6~3.0 m·s-1;有效起沙风作用时间存在明显的区域差异,其中巴音布鲁克起沙风天数占全年总天数的55.59%,焉耆、轮台、巴音郭楞及和静分别为18.75%、12.72%、11.48%、11.23%,其余各站均低于10%;随着风速等级的增加,起沙风出现的频率相应减少,基本上都集中在6.1~10.0 m·s-1;研究区方向变率指数(合成输沙势/输沙势,RDP/DP)0.49~0.68,属于中比率,风况特征属于纯双峰风况或锐双峰风况。输沙势属于低风能环境,且存在较大的区域差异。

关键词: 博斯腾湖流域, 平均风速, 起沙风速, 输沙势

Abstract:

By statistics and calculation of the wind data, systematic research is made on the characteristics of wind regime in the Bosten Lake basin. The annual average wind speed is rather small, generally, it is 1.6-3.0 m·5s-1; the effective time of sand-driving wind when the wind speed is more than or equals to 6.0 m·5s-1 is obviously different in various regions. Among them, the days of sand-driving wind in Bayinbuluk account for 55.59% of the total number of days, in Yanqi, Luntai, Hejing, it is 18.75%, 12.72%, 11.48%, 12.72% respectively, in the rest of the stations it is lower than 10%. As the wind speed scale increases, the frequency of sand-driving wind reduces, and it is mostly concentrated 6.1-10.0 m·5s-1; Wind variability index is between 0.49 to 0.68 in research region, and it belongs to middle ratio, the characteristics of wind conditions belong to blunt bimodal or sharp bimodal; sand-transporting potential belongs to low wind energy environment, and there are huge regional differences.

Key words: Bosten Lake basin, mean wind speed, sand-driving wind speed, sand-transporting potential
