| 摘 要： | 在雾凉季和干热季 ,对西双版纳热带季节雨林林窗进行了小气候垂直观测 ,通过对观测资料的统计分析 ,得出热带季节雨林林窗区域昼间树表温、气温、水汽压及相对湿度的时空分布和变化规律 ,发现热带季节雨林林窗边缘壁面不仅具有显著的热力效应 ,而且具有明显的水汽效应 ,并以林窗北侧边缘效应最为明显 .如此的热力、水汽效应势必对林窗区域立体空间的环境异质性产生深刻影响

| Abstract: | Vertical measurements of microclimatic elements of canopy gap in tropical seasonal rain forest were conducted in fog cool and dry hot season in Xishuangbanna.Making use of these data,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 finding showed that at the edge of canopy gap,there had not only remarkable thermal effect but also significant water vapor effect,in particularly at the north edge,which would greatly influence environmental heterogeneity in tridimensional space of canopy gap. |

| Keywords: | canopy gap edge of canopy gap thermal effect water vapor effect temporal spatial distribution |
