摘　　要：为摸清萧氏松茎象Hylobitelus xiaoi zhang受害松林的环境因子特征,应用林地环境因子常规观测方法进行观测,结果表明:8月份受害松林地面平均光照强度、地面温度、距地表20cm高处温度、5cm深处土壤温度、70cm高处蒸发量分别为374.8lx、25.4℃、27.1℃、25.5℃、1.6mm,分别比健康松林低94.8%、7.0%、4.6%、5.9%、27.3%,受害松林在距地表20cm高处空气相对湿度为85.8%,比健康松林高7.1%。由实验得知,萧氏松茎象受害松林的光照强度、地面温度、空气温度、土壤温度、蒸发量均比健康松林低,空气相对湿度比健康松林高,距地表越近,这一差异就越明显。两类林分中的光照强度、空气温度、土壤温度、空气相对湿度4因子均存在明显差异,是影响萧氏松茎象发生的重要因素。To find out the characteristics of environmental factors in the plantation of slash pine, Pinus elliottii Engelm. with and without infestation of Hylobitelus xiaoi Zhang, this paper uses methods in conventional observation to observe environmental factors. The results showed that the average light intensity on the surface, the average surface temperature, the average temperature at the height of 20 cm, the soil average temperature at depth below 5 cm and the evaporation capacity at the height of 70 cm in the slash pine plantation infested were 374. 8 Ix, 25.4℃ August, which were 94. 8% 27. 1℃, 25.5℃, 1.6 ＇mm respectively in 7.0%, 4. 6%, 5.9%, 27.3% respectively less than those in that without the weevil＇ s infestation. The relative humidity at the height of 20 cm was 85.5 % in the slash pine plantation infested, which was 7.1% higher than that in the slash plantation without the weevil＇ s infestation. So the light intensity, the surface temperature, the air temperature, the soil temperature and the evaporation capacity were lower, and the relative humidity was higher in the slash pine plantation infested with Hylobitelus xiaoi Zhang than those in that without infestation of the weevil. The light intensity, the surface temperature, the air temperature, the soil temperature and the evaporation capacity is an obvious difference in different stand. This four factors are important factors to affect Hylobitelus xiaoi Zhang.
