摘要： 运用自动气象站对天山中部白杨沟天然林区森林内外气象因子进行同步观测,分析晴-多云、阴雨天森林的气温、相对湿度、土壤温度日变化和季节变化特征。结果表明:各季节林冠层平均最高温度和平均最低温度林内均低于林外,平均最高温度林内比林外低2.04℃,平均最低温度林外比林内高1.95℃。冠层相对湿度的平均值较林外高出3.63％,4月相对湿度最大。天山中部白杨沟天然林区森林的防风效果在不同季节均十分显著,各季节平均风速降幅在0.94m/s以上,冬季的防风效果最好。在春、夏季,林内外土壤温度差值明显增大,且自上而下逐步降低,在秋、冬季节差值较小。

Abstract: In this paper, the microclimate characteristics in and out of the Picea schrenkiana forests in the Tianshan Mountains, China are analyzed and compared based on observed meteorological data, and the seasonal and daily change characteristics of air temperature, relative humidity and soil temperature in and out of the forests under different weather are discussed. The results show that the seasonal average canopy maximum and minimum temperatures out of the forests were higher than those in the forests, the average maximum and minimum temperatures in the forests were 2.04 ℃ and 1.95 ℃ lower than those out of the forests respectively. The average canopy relative humidity in the forests was 3.63% higher than that out of the forests, and the relative humidity in April was the highest. The windproof effect of the natural forests in the central Tianshan Mountains was significant in every season, the average wind speed was reduced by 0.94 m/s, and the windproof effect was the best in winter. In spring and summer, the difference of soil temperature in and out of the forests was increased significantly, it was reduced gradually from topsoil to deep soil, but it was low in autumn and winter.

Key words: forest, microclimate, air temperature, humidity, soil temperature, natural forest zone, Baiyanggou, Xinjiang
