摘要:

利用2004—2008年沙尘暴观测站网哈密、塔中与和田的TSP观测资料,同时结合铁干里克、民丰和喀什2007年4月开始的TSP、沙尘天气等相关资料,给出了塔里木盆地TSP时空分布特征及变化特征,同时分析了影响TSP质量浓度变化的主要因素。结果表明:①塔里木盆地东部TSP质量浓度最低,南缘最高,往盆地的西缘逐渐降低,塔中一直处于较高值。影响TSP质量浓度高低分布的主要因素是沙尘天气,沙尘天气日数越多,则浓度越高。②2004—2008年TSP年平均质量浓度哈密最低,其次为塔中,最高为和田。③2004—2007年哈密、塔中与和田TSP平均质量浓度春季最高,其次是夏季和秋季,冬季最低。④哈密、塔中与和田2005—2008年TSP质量浓度每年不同时间段各不相同。

Abstract:

In this paper, the spatial-temporal distribution and change characteristics of TSP in Tarim basin were analyzed based on the TSP data during 2004—2008 from sandstorm observatory network in Kumul, Tazhong and Hotan, and the TSP data in period of April 2007 to March 2008 from Tikanli, Minfeng and Kashgar stations, at the same time the factors influencing the TSP mass concentration were analyzed. The results are as follows: ①The TSP concentration over the east of Tarim basin was the lowest, that over the southern margin was the highest; The TSP concentration decreased gradually westward to the edge of the West Basin, and Tazhong had a relatively high value all the while. Dust weather was a major factor influencing the distribution of TSP concentration, and the more the dust weather days the higher the TSP concentration. ②The annual average TSP concentration from 2004 to 2008 was the lowest in Kumul, the highest in Hotan, the medium in Tazhong. ③The seasonal average TSP concentration distribution during 2004—2007 in these three regions showed the highest value in spring, the second in summer, the third in autumn and the lowest in winter. ④The TSP concentrations in Tarim basin from 2005 to 2008 were different in different regions and different periods, suggesting a close relation to sand-dust weather phenomena.
