摘　　要：为客观了解兴隆山森林小气候变化情况,本研究以兴隆山森林林内、林外2021年气象观测数据为基础,对该区空气温度、湿度、光合有效辐射、风速、风向5个气象因子进行对比分析,揭示兴隆山森林小气候变化特征。结果表明:林外平均气温、最高气温和光合有效辐射均高于林内,且均呈现先增长后减小的趋势;林外空气湿度、风速低于林内,林内以西南偏南风为主,林外风向以西南偏西为主,空气湿度在生长季(5—10月)内呈现增长趋势;林内林外空气温度均在7月达到最高温(林内16.20 ℃、林外20.15 ℃),空气湿度在10月达到最大值(林内91.01%、林外79.30%),光合有效辐射在7月份达到最高值(林内6.39 W·m^(-2)、林外95.82 W·m^(-2)),7月风速最大(林内2.04 m·s^(-1)、林外1.99 m·s^(-1))。因此,掌握森林小气候变化特征,充分利用其对森林环境效益的促进作用,通过更加科学方式经营管理森林资源。In order to objectively understand the forest microclimate change in Xinglong Mountain,this study is based on the meteorological observation data of inside and outside of the forest in Xinglong Mountain in 2021.The five meteorological factors of air temperature,humidity,photosynthetic active radiation,wind speed and wind direction were compared and analyzed to reveal the characteristics of forest microclimate change in Xinglong Mountain.The results showed that the average temperature,maximum temperature and photosynthetic active radiation outside the forest were higher than those in the forest,and all increased at first and then decreased,and the air humidity and wind speed outside the forest were lower than those in the forest,and the wind direction outside the forest was mainly southwest by west,and the air humidity showed an increasing trend in the growing season(May-October).The air temperature inside and outside the forest reached the highest in July(16.20℃inside and 20.15℃outside the forest),and the air humidity reached the highest in October(91.01%inside and 79.30%outside the forest),the photosynthetic active radiation reached the high-est value in July(6.39 W·m^(-2) inside and 95.82 W·m^(-2) outside),and the wind speed was the highest in July(2.04 m·s^(-1) inside and 1.99 m·s^(-1) outside).Therefore,mastering the characteristics of forest microclimate change and making full use of its role in promoting forest environmental benefits can scientifically and effectively manage forest resources.
