| 摘 要： | 本文应用气孔计测定秋茄群落的蒸腾强度、气孔导度和几个生态因子的季节性变化。结果表明：一年中，秋茄群落的蒸腾强度、气孔导度有明显的上升和下降规律：夏季＞春季＞秋季＞冬季；蒸腾作用的季节性变化主要是受温度变化的影响。秋茄群落的年蒸腾量达７８８．５ｋｇＨ２Ｏ·ｍ－２，其中，以夏季为最高，达２７６．１ｋｇＨ２Ｏ·ｍ－２，冬季最低，为１１５．８ｋｇＨ２Ｏ·ｍ－２，年平均日蒸腾量为２１６０．２３ｇＨ２Ｏ·ｍ－２。

| Abstract: | Seasonal changes of transpiration and stomatal conductance in Kandelia candel community and some ecological factors were determined by porometer. The results showed that transpiration and stomatal conductance change with seasons in the order:summer>spring>autumn>winter,and their changes are influenced mainly by the change of temperature. The yearly transpiration content of Kandelia candel communnity are 788 5 kg H 2O m -2 y -1 ,with the peak value appearing in the summer (276 8 kg H 2O m -2 ), and lowest value in the winter (115 8 kg H 2O m -2 ). The average diurnal transpiration content is 2160 23 g H 2O m -2 d -1 . |
