摘　　要：为探讨浙江省不同典型森林群落对大气环境的改善程度,选取针阔混交林、常绿阔叶林、毛竹林3个典型森林群落,通过3个月的野外调查测量群落内空气负氧离子、PM系列等指标来评价大气环境。结果表明:(1)8月比6月和7月的负氧离子更高;(2)从日变化角度看,负氧离子上午低,傍晚高,而PM系列上午高,傍晚低;(3)从不同典型森林群落角度看,人居适宜程度为针阔混交林>常绿阔叶林>毛竹林;(4)从因子的相关性角度看,PM2.5与PM10、PM1.0有显著正相关性,与负氧离子、温度有弱负相关性,与光合有效辐射、湿度、风速和UVB没有相关性。在炎炎夏日出行时,从人居的适度的角度出发,选择在8月傍晚的针阔混交林里休憩时负氧离子最高,PM系列指标最低。In order to explore the effect of different typical forest communities on the improvement of the atmospheric environment of Zhejiang Province,three typical communities of needle mixed forests,evergreen broad-leaved forest and mosobamboo forest were selected as the material.The air negative oxygen ions,PM series and other indexes in the communities were measured to describe the atmosphere environment.The result of three months,field investigation,show that： 1） the content of negative oxygenions in August is higher than in June and July; 2） from the perspective of daily variation,the content of negative oxygen ions is low in the morning and high in the evening,and PM series high in the morning and evening is low; 3） from the perspective of different typical forest communities the order of human resideential suitability is needle forest mixed forest evergreen broad-leaved forest moso bamboo forest; 4） from the perspective the correlation of the factors,PM2.5 has significant positive correlation with PM10 and PM1.0,has a weak negative correlation with the content of negative oxygen ions,temperature,and has no correlation with photosynthetic active radiation,humidity,wind speed and UVB.In the hot summer,for the sake of comfort,reisure in mixed needle forest in the evening in August when the content of negative oxygen ions is the highest,and PM series is the lowest.
