Study on the Characteristics of Forest Microclimate in Xinglong Mountain in Gansu Province
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.
