%X Based on the data obtained from vertical gradient measurements of microclimatic elements of canopy gap in tropical secondary forest of Xishuangbanna in fog cool and dry hot season,the daytime characteristics of temporal spatial distribution and variation of trunk surface temperature,air temperature,water vapor pressure and relative humidity in canopy gap were discussed. The data showed that gap edge had not only a remarkable thermal effect,but also a significant water vapor effect. These effects resulted in environmental heterogeneity in canopy gap. The results provided a basis for further studying heat and water vapor transport,microclimatic formation,biodiversity,and forest succession in canopy gap.
