摘要
探究四季森林空气中颗粒物污染的特征变化情况及其对生态系统的影响。选取六种典型人工森林群落作为研究群落,观察四个季节各种森林群落的大气颗粒物污染浓度变化情况,依据四种季节的均值获得净化颗粒物能力强的森林群落。从年均值来说,以秃瓣杜英、湿地松为优势树种的针阔混交林的PM_(2.5)的吸附能力最强,对于PM_(10)来说,以香樟为优势树种的常绿阔叶林的吸附能力最强。温度、湿度与富氧离子含量与颗粒物呈现强烈负相关。森林空气中颗粒物污染特征的变化与季节相关,随着浓度变化,对于生态系统也会造成一定影响。
This paper investigates the characteristic changes of particulate matter pollution in forest air in four seasons and its effects on ecosystem.Six typical artificial forest communities were selected as research communities to observe the change of atmospheric particulate pollution concentration of various forest communities in four seasons,and the forest communities with strong ability to purify particulate matter were obtained according to the mean values of the four seasons.In terms of annual mean value,the adsorption capacity of PM_(2.5) was the strongest in the pin-wide mixed forest with Duying and pine,and the adsorption capacity of PM_(10) was the strongest in the evergreen broad-leaved forest with cinnamomum camphor as the dominant tree.Temperature,humidity and oxygen-rich ion content are strongly negatively correlated with particulate matter.The change of particle pollution characteristics in forest air is related to the seasons,and with the change of its concentration,the ecosystem will be affected to some extent.
