摘　　要：利用2004、2005年3月至5月塔克拉玛干沙漠腹地塔中气象站的能见度仪自动监测资料,气温、气压、风速、相对湿度等地面气象常规沙尘观测记录以及PM10自动监测仪观测资料,分析了塔中水平能见度变化特征以及与气象因子、PM10的相关关系,气象因子与PM10对水平能见度有一定的制约关系,但并非简单的线形关系,不同时段,不同天气条件下,各因素的作用不同。The basal meteorological data for this study comprises the daily visibility data automatically ob- served from April 1 to May 31 in 2004 and 2005 at the Tazhong Meteorology Station which situated in Taklimakan Desert, the routine ground meteorological dust-storm such as temperature, pressure, wind speed, relative humidity, and the PM^o data from the automatic monitor. Analysis on correlation among visibility change characteristics and meteorological factors, PM10 concentration shows that meteorological factors and PMloconcentration have some controlling function on horizontal visibility, but not simple linear correlation. Under different meteorological condition and in different period, the effect of every factor is different.
