厦门市PM_(10)浓度空间与时间差异分析

Spatial and Temporal Variation of PM_(10) Mass Concentrations in Xiamen

在厦门市环境大气污染物中,PM10是其首要的大气污染物。厦门市大气中的PM10浓度受天气和气候以及土地利用类型、交通排放、工业状况等诸多自然因素和人为因素的共同影响而呈现出一定的时空变化规律,文章对厦门市2001年至2002年PM10浓度的空间变化和时间变化特点进行了分析,揭示了影响厦门市环境大气中PM10浓度空间变化和不同尺度的时间变化的影响因素。

PM_(10) is the principal air pollutant in Xiamen. And the PM_(10) concentration is influenced by different natural factors and human factors such as climates, land usage types, traffic emission, industry conditions and so on to turn out certain characters following spatial and temporal variation.The characters of spatial and temporal variation of PM_(10) mass concentration from 2001 to 2002 in Xiamen are analysed and the corresponding factors affecting such variation are revealed.
