博乐市空气质量时空变化特征分析

以2001—2008年博乐市空气污染物的监测数据和统计年鉴资料为依据,对其平均浓度的时空变化特征进行分析。结果表明:博乐市空气总体良好,博乐市空气污染物的时空变化特征比较明显,SO2、NO2月变化曲线呈"U"字型,且冬春季节重于夏秋季节,这主要是由冬季取暖和不利气象条件造成的。2006年以来,博乐市TSP浓度呈现明显的空间转化特征,文教区的浓度略高于混合区,应引起环保部门的重视。

Analysis on Spatio-temporal Change Characteristics of Atmosphere Quality in Bole city.

According to the monitored date of air pollutants within Bole city from 2001 to 2008,the spatio-temporal change characteristics of the city air pollutant concentrations is analyzed.The results show that the air pollution of Bole city is well on the whole.Spatial and temporal change of air pollution is obvious,for example,the curves of monthly change of SO2 and NO2 are all U-shaped,and air pollution degrees in winter and spring is more serious than in summer and autumn due to heating in winter and disadvantageous meteorological conditions.Spatial shift character of TSP concentration in Bole city has occurred since 2006,and the concentration of the cultural and educational districts is higher than the mixing districts.These differences should be paid more attention by environmental protection departments.
