【摘要】 森林温度特征的研究是揭示森林生态系统功能、评估森林环境效益的基础。对2004年长白山阔叶红松林林内外空气温度和土壤温度进行了观测,结果表明:林内外空气温度、土壤温度明显不同。白天林内气温一般低于林外,夜间高于林外。昼间气温差夏季较大,7月平均差值为1·6℃;夜间气温差冬季较大,1月平均差值为1·5℃。空气温度和土壤温度的日振幅总是林内小于林外,7月空气温度日振幅林内比林外低1·7℃,4月土壤温度日振幅林内比林外低5·8℃。更多还原

【Abstract】 The study of temperature characteristics in forest is the basis of revealing the functions of forest ecosystem and assessing the environmental benefit of forest. In 2004, the air and soil temperature in and out of the broadleaved-Korean pine mixed forest in Changbai Mountains were observed, and the results showed that the air temperature in the forest was always lower at daytime and higher at nighttime than that out of the forest. The difference of air temperature at daytime was bigger in summer, with a mean of 1.6 ℃ in July, while that at nighttime was bigger in winter, with a mean of 1.5 ℃ in January. The diurnal amplitude of air and soil temperature was always lower in the forest than out of the forest, with a difference of air temperature in July being 1.7 ℃ and of soil temperature in April being 5.8 ℃.更多还原
