环境科学与工程-福建省大气中PM10污染特征研究论文

摘 要本文是以福建大气中 PM10为研究对象，阐述了能够使得 PM10质量浓度有所变化的因素(即温度、风速、降雨量)，分析了福建省 PM10的时间变化规律(即月份与季度的变化规律、空间变化特征)。论文的主要结果如下：(1)福建省九地市可吸入颗粒物 PM10质量浓度通常在春季和冬季高于秋季，夏季比之都低的季节性变化规律。(2)福建省九地市可吸入颗粒物 PM10质量浓度一般在 1、12 月份高，6、7 月份低的月度变化规律。(3)气象条件对大气颗粒物 PM10的影响可以说是很明显，其中 PM10的质量浓度与平均温度成反比。也就是说，温度越高，PM10 的质量浓度越低；其次，较高的风速在一定程度上有利于污染物的冲刷与分散，能降低了 PM10的质量浓度。最后，降雨量与 PM10的质量浓度的关系十分密切，降雨量总量越多，则 PM10的质量浓度越低。关键词：PM10;温度;风速;降雨量;时空变化规律AbstractBased on the atmospheric PM10 in Fujian Province, the factors affecting the PM10 mass concentration were discussed. temperature, wind speed, rainfall), and analyzed the time variation law of Fujian PM10. monthly and quarterly variation laws, spatial variation characteristics). following are the main results of the paper :(1) the concentration PM10 respirable particulates in nine cities of fujian province usually shows that the spring and winter are higher than the autumn, which is lower than the seasonal variation law in summer .(2) the PM10 concentration of respirable particulates in jiudi city of fujian province is generally higher in january and december and lower in june and july. (3) The influence of meteorological conditions on the PM10 of atmospheric particulate matter can be said to be obvious, in which the mass concentration of the PM10 is inversely related to the average temperature, that is, the higher the temperature, the lower the mass concentration; secondly, the higher the wind speed is, to some extent, conducive to the erosion and dispersion of pollutants, whi...
