摘　　要：依据辽宁冰砬山森林生态系统国家定位观测研究站2014—2016年天然次生林内2m层空气温湿度及林外1.5m层空气温湿度观测数据,分析冰砬山区林内外空气温湿度差异。结果表明:冬季林内气温高于林外,夏季林内低于林外;林内气温日较差低于林外;白天林内气温低于林外气温,夜间林内高于林外;林外月平均空气湿度高于林内;林内空气湿度日较差低于林外;白天林内空气湿度高于林外,夜间林内空气湿度低于林外。森林调节空气温湿度的作用具有规律性。Natural secondary forest is an important type of forest vegetation in eastern Liaoning ecological balance.Based on the observation data of air temperature and humidity in the 2 mlayer in the natural secondary forest from the year of 2014 to 2016 and the data of the air temperature and humidity in the 1.5 mlayer outside the forest,the difference of temperature and humidity were analyzed in the air inside and outside the forest of the Bingla Mountain area.Result shows that：temperature in forest in wintertemperature outside the forest;temperature in forest in summerthe temperature outside the forest;diurnal range of temperature in forestdiurnal range of temperature in and outside forest;daylight temperature in forestdaylight temperature outside the forest;forest temperature in forest at nightforest temperature outside the forest at night.Average monthly air humidity outside the forestaverage monthly air humidity in the forest;daily range of air humidity in the forestdaily range of air humidity outside the forest;diurnal range of air humidity in the forestdiurnal range of humidity outside the forest;air humidity in the forest during the day air humidity outside the forest,humidity in the forest at nighthumidity outside the forest.This shows that the forest has the effect of regulating the temperature and humidity of the air.
