摘　　要：以安徽查湾自然保护区甜槠（Castanopsis eyrei）林为研究对象,分析了不同大小林隙温度因子变化情况.结果表明：不同大小林隙及非林隙林分内气温日变化呈单峰型,地表以上1m处的气温峰值出现在12：00-14：00.在整个生长季中,气温变化表现为：大林隙〉中林隙〉小林隙〉非林隙.地表温度日变化趋势与气温基本一致,呈现单峰型,最高温度出现在中午12：00-14：00,较光照日变化最大值滞后,平均日地表温度是：大林隙〉中林隙〉小林隙〉非林隙.地表温度在生长季内变化为生长初期、末期较低,生长旺盛期较高.The Castanopsis eyrei forest was Zhawan Natural Resource Protection Region of Anhui Province was selected for field investigation,the different size gaps of temperature changes was analyzed,The results showed that the daily temperature change of different sizes of forest gaps and nongap stands revealed a unimodel.The peak of the temperature was at 12:00to 14:00.Throughout the growing period,the temperature performance for different gaps was as follows:big gap>middle gap>small gap>non-gap.Daily temperature change at ground surface was different gaps and non-gap location revealed a unimodel,which was similar to the daily air temperature change pattern.Its peak appeared at 12:00to 14:00.The time of the maximum temperature appeared later compared with daily light change.The average temperature performance was as follows:big gap>middle gap>small gap>non-gap.Changes was surface temperature for the growth was the early growing season,the it was low was the late period,vigorous growth time was longer.
