青岛市不同类型城市森林气象因素比较

Analysis of Regional Meteorological Factors and Features based on Qingdao Forest Ecosystem Research Station

基于森林生态定位站的观测数据,对比青岛市域内的城市园林、南部沿海防护林、北部生态屏障林一年时间中不同季节、不同天气等影响因素,针对森林生态系统的太阳辐射、空气温度、空气相对湿度气象因子进行探讨和分析。结果表明:林冠层对太阳辐射起到一定的遮蔽作用,郁闭度大、林窗小的林内太阳辐射强度整体减弱,夏季和秋季正午减弱作用明显;北部生态屏障林的气温日变化和年变化幅度大于其他林地,南部沿海防护林森林对空气温度和湿度的调节作用明显,其日变化和年变化幅度最小、波动幅度最小;冬季是森林中最为干燥的季节,夏季的夜间森林空气最为湿润。

Based on the observation data of Qingdao Forest Ecosystem Research Station from 2020 to 2021,comparison among different sources of city garden,southern coastal shelterbelt and northern ecological barrier forest in Qingdao,solar radiation,air temperature,air humidity etc.,were applied to analyze the meteorological factors in forest of the station.The results show:(1)forest canopy can shield the solar radiation,due to canopy density and small gap in forest reducing the solar radiation,especially in summer and autumn.(2)Daily and annual variation of temperature in northern ecological barrier forest is larger than other forest region.In southern coastal shelterbelt,the moderator effect on air temperature and air humidity is most obvious.Its daily and annual variation ranges are the smallest.(3)The forest is driest in winter and wettest in summer night.
