title: [A primary study on thermal effect of soil-plant-atmosphere continuum in tropical seasonal rain forest gap].
abstract: Made use of measurement data of microclimatic elements of canopy gap in tropical seasonal rain forest in fog-cool and dry-hot season in Xishuangbanna, the daytime characteristics of temporal-spatial distribution and variation of soil surface temperature, air temperature, and leaf temperature of understory plants in canopy gap were discussed. The finding showed that influenced by fog and solar altitude, the maximum value of microclimatic elements displayed at different site of gap in different time and season and there existed phenomenon about higher value area of leaf temperature dynamic displacement. In addition, the direction of heat transferring of soil-plant-atmosphere continuum varied with time and season, indeed at the same time, the different part of gap had the different heat transferring directions. The results would supply a research basis for further studying heat and water vapor transport, microclimatic formation, biodiversity and succession of canopy gap.
