中文摘要	利用2009年7月4日~ 29日塔中野外试验观测数据,基于MARTICORENA和SHAO提出的2种起沙模式参数化方案,初步探讨塔中地区不同沙尘天气临界起沙风速,所得结论如下:(1)非沙尘天气,沙尘撞击颗粒数≤10 000;扬沙天气,10 001≤沙尘撞击颗粒数≤20 000;沙尘暴天气,沙尘撞击颗粒数≥20 001。(2)基于MARTICORENA起沙参数化方案,临界起沙风速的平均值为4.88 m·s~(-1),基于SHAO起沙参数化方案,临界起沙风速的平均值为6.24 m·s~(-1),临界起沙风速在非沙尘天气最大,在沙尘暴天气最小。(3)在观测期间沙尘水平通量为732.9 kg·m~(-1),其中非沙尘天气125.2 kg·m~(-1),扬沙天气80.9 kg·m~(-1),沙尘暴天气526.8 kg·m~(-1),SHAO起沙参数化方案适合估算总沙尘水平通量以及非沙尘和扬沙天气的沙尘水平通量,MARTICORENA起沙参数化方案适合估算沙尘暴天气沙尘水平通量。
英文摘要	This paper is probed into the threshold velocity(ut) calculation of Tazhong area,Taklimakan Desert,Xinjiang,China using the parameterization scheme.Firstly,we classified the dust weather combining the date of sand saltation,and then acquired the threshold velocity through the schemes of MARTICORENA and SHAO respectively.In order to test the accuracy of the ut,we estimated the horizontal sand flux,and the results are as follows:(1) In the non-dust weather,the number of saltation particles was less than or equal to 10 000;when the sand blowing,the number of saltation particles was between 10 001 and 20 000;and in the sand storm,the number of saltation particles was more than 20 000.(2) The average threshold velocity was 4.88 m·s~(-1) with the parameterization scheme of MARTICORENA and the average threshold velocity was 6.24 m·s~(-1) with the parameterization scheme of SHAO,the threshold velocity was the highest in non-dust weather and the smallest in sand storm.(3) During the study period,the total horizontal dust flux was 732.9 kg·m~(-1),and the horizontal dust fluxes were 125.2,8 0.9 and 526.8 kg·m~(-1) in non-dust weather,the sand blowing and the sand storm respectively.The parameterization scheme of SHAO was suitable to estimate the horizontal dust flux in the study period,the non-dust weather and the sand blowing,while the parameterization scheme of MARTICORENA was suitable to estimate the horizontal dust flux of sand storm.
