摘　　要：自然干扰形成林窗后,会造成林窗下的光照和温度发生明显变化。通过调查大别山五针松林林窗、林缘和林下微气候动态变化规律,结果表明:林窗、林缘和林下,环境因子的日变化差异明显。其中,在林窗阶段的微气候要比其他2个阶段变化更大。不同斑块类型下光照、空气温度和土壤表面温度存在显著差异。Gap, caused by natural disturbance, can cause the change of light and temperature in the forest patch obviously.Based on an investigation in a sample of a Pinus dabeshanensis forest in Dabieshan Mountains, we recognized three patch types including gap, gap adjacent and closed canopy and analyzed their microclimate characteristics.The daily change patterns of microclimate characteristics in three patch types were different.The light intensity and air temperature were much greater in gap than in the gap adjacent and closed canopy.The light intensity, air temperature and soil surface temperature had significant difference under different patch types.

关 键 词：光照 温度 异质性 斑块类型
