摘要:大气颗粒物( particulate matter，PM)中的生物成分会严重引起组织炎症，并且有传播给人类、植物和家畜病原菌等危害。通过FDA(荧光素二乙酸酯)水解法定义石河子市微生物气溶胶的酶活性水平，采用Pearson双变量分析方法分析其影响因素。结果表明，石河子市的细颗粒物中微生物酶活性最高的是夏季，最低的是冬季。酶活性水平与温度(R=0.587，n=75，P<0.01)、细颗粒物浓度(R=-0.704，n=75，P<0.01)和风速(R=0.605，n=75，P<0.05)存在显著相关性。通过逐步多元线性回归方程可知温度是最显著的影响因素。研究为城市重点区域环境规划和总体环境改善方案提供基础科学数据，对石河子的大气环境研究有重要的参考价值。

Abstract:The biological components of particulate matter would cause serious inflammation of the tissue, they make the harmful effects by spreading to humans, plants and livestock. In this study, the FDA (fluorescein diacetate) hydrolyzation method was used to define the microbial activity level of bioaerosols in Shihezi city, and the Pearson bivariate analysis method was adopted to analyze its influencing factors. The results showed the highest level of microbial activity in fine particulate matters was in summer, the lowest was in winter. And there are significant correlations between the temperature (R=0.587,n=75,P<0.01), concentration of fine particle(R=-0.704, n=75, P<0.01) and wind speed (R=0.605, n=75,P<0.05). It has been indicted that the temperature plays the most significant role in microbial activity by stepwise multiple linear regressions. This study aims to provide basic scientific data for methods and processes which evaluating regional investment environment in key regions of urban areas and important reference value for research on atmospheric environment of Shihezi.
