摘　　要：林内外气象要素的分析可以揭示林区内小气候动态变化规律,同时也是明晰枯落物在天然状态下生态水文效应的前提。选取广西的典型林地,采取林内外定位对照观测方法,对试验区内冬季(10—4月)的林内外气象要素及冠层截留效应进行研究。结果表明:林地冠层截留效应与降水量相关;林内温度、湿度、风速均与林外有显著相关性;林内外潜在蒸散发变化趋势明显,冬季林外潜在蒸散发远大于林内。The analysis of meteorological elements inside and outside the forest can reveal the dynamic change law of microclimate in the forest area,and it is also the premise of clarifying the ecological hydrological effect of litter in the natural state.Taking the typical forestland in Guangxi Zhuang Autonomous Region as an example,the meteorological elements in and out of the forest in winter(October-April)in the study area were measured by using the method of in-and out-of-forest comparison and in-forest positioning observation combined with indoor analysis,analysis of canopy interception effect.Result shows that canopy interception was related to precipitation,temperature,humidity and wind speed in forest were significantly related to those outside the forest,and the potential evapotranspiration in and outside the forest have significant change trend,the potential evapotranspiration outside the forest is much greater than that inside the forest in winter.
