摘要

摘要: 为探讨热带季节雨林林冠上方大气稳定状态,为通量计算提供依据,利用2003~2004年热带季节雨林林冠上方的涡度相关法观测资料,对西双版纳热带季节雨林树冠上生态边界层内大气的稳定度频率分布进行了分析研究。计算了稳定度参数(z/L),并对大气稳定度类型进行了划分,分析了大气稳定状态的时间变化。结果表明:在热带季节雨林林冠上方的大气稳定度频率分布存在明显的日变化。昼间不稳定状态占优势,晚上以稳定状态为主;在早晨和下午稳定状态和不稳定状态频率分布易发生变化,导致中性的大气稳定状态更容易出现;而各大气稳定状态的频率分布年和季节变化相对较小,大气不稳定状态出现频率以雾凉季最高、干热季最低;稳定状态出现频率以干热季最高、雨季最低;中性状态出现频率以雨季最高、雾凉季最低。

Abstract: Using the data between 2003 and 2004 by three-anemometers,we discussed the frequency distribution of atmospheric stability above the tropical seasonal rainforest canopy in Xishuangbanna,Southwest China.The Monin-Obukhov length z/L has been calculated and then divided into seven parts by different conditions.The results showed that the frequency of atmospheric stability had significant daily variation.Stable condition was dominant in the day,and unstable condition mainly occurred at night.Atmospheric stability change always took place in the morning and afternoon,and growth of the frequency of near-neutral condition was observed at the same time.The results also showed that the frequency of unstable condition was the highest in foggy-cool season but the lowest in dry-hot season;the frequency of stable condition was the highest in dry-hot season but the lowest in rain season;the frequency of near-neutral condition was the highest in rain season but the lowest in foggy-cool season.
