兴隆山保护区湿度观测研究

通过对峡口点21年、羊道沟点17年、新庄沟点18年观测统计得出:兴隆山保护区的年平均湿度73%,范围在35%~95%之间。其中峡口点67%,羊道沟点81%,新庄沟点72%。月平均湿度与年平均湿度相同,范围在90%~60%之间。森林对林内湿度影响很大,林内比林缘高,密林比疏林大。一年各月最高湿度出现在9月,最低出现在1月,逐月变化显著而有规律,夏季为68%,最低,依次春季为70%,冬季72%,秋季82%,最高,这与降水量关系极大。湿度的日变化很小,但很有规律,最大出现在白天,夜间小,最低出现在日出前。

Observation Study on Humidity of Xinglongshan Nature Reserve

Through observation statistics of experimental site in Xiakou for 21 years,experimental site in Yang-daogou for 17 years,and experimental site in Xinzhuanggou for 18 years.The results showed： 73% of the annual aver-age humidity of experimental site in Xinglong Nature Reserve was in the range 35% to 95%.Among all the sites,ex-perimental site in Xiakou,which point 67%,81% experimental site in Yangdaogou,72% of experimental site in Xinzhuanggou.Monthly average humidity and year average humidity were the same,the range of 90% to 60%.The ef-fect of forest on forest humidity,and it in forest was high than in forest edge.The month of highest humidity in a year was September,the lowest in January,the monthly change was significant and regular,68% in summer and it was the lowest,followed by spring,70%,72% in winter and 82% in autumn and it was the highest,which had great relationship with precipitation.Daily variation of humidity was small,but it was very regular,it was the biggest in the daytime,at night it was small,and the lowest occurred before sunrise.
