摘要:
 空气微生物浓度与人类健康和公共卫生安全息息相关。为探明绿地通过植被类型、垂直结构、环境因子和土壤微生物对空气微生物分布的影响，选择了8块具有典型植被特征的绿地，采用自然沉降法取样并观测空气微生物冬春季的分布情况。结果表明，校园不同绿地空气微生物浓度春季显著高于冬季。受季节、植物种类和垂直结构影响，不同绿地空气减菌作用彼此间显著差异，所有绿地均能有效抑制空气细菌，且在春季表现出更好的减菌效果，对空气真菌基本无抑制作用，针叶林和乔草结构分别为减菌作用最佳的植被类型和垂直结构。环境因素和绿地垂直结构与空气微生物浓度存在显著线性回归关系，空气细菌浓度受温度影响最大，空气真菌浓度受湿度影响最大。土壤细菌多样性和丰富度与空气细菌浓度显著正相关，土壤真菌多样性与空气真菌浓度显著负相关。
Abstract:
 Airborne microorganism (AM) concentration is closely related to human health and public health safety.In order to ascertain the influences of vegetation types,vertical structures,environmental factors and soil microorganism on the distribution of AM,8 green spaces with typical vegetation types were selected in the south campus of Northwest A&F University,using the natural sedimentation method to observe the distribution of AM in winter and spring.The results showed that the concentration of AM in different green spaces of the campus was significantly higher in spring than that in winter.Influenced by seasons,plant species and vertical structures,there was significant difference in air bacteria-reducing effect among different green-spaces.All green spaces could effectively inhibit air bacteria,and showed better bacteria-reducing effect in spring,but could not inhibit air fungi.Evergreen coniferous forest had the best bacteria-reducing effect in all vegetation types,and arbor-grass structure had the best bacteria-reducing effect in all vertical structures.There was a significant linear regression relationship between environmental factors and green space structure and air microbial concentration.The concentration of airborne bacteria was mostly affected by temperature,while that of airborne fungi was mostly affected by humidity.Soil bacterial diversity and richness were positively correlated with airborne bacterial concentration,while soil fungal diversity was negatively correlated with airborne fungal concentration.
