摘要：１９９２～１９９８年以来的实地观测研究表明，金沙江干热河谷主要造林树种中，大叶相思、绢毛相思、赤桉和乡土树种坡柳等树种旱季水分自然饱和亏缺较大，造林比较成功的树种可分为蒸腾作用较强的乡土树种和桉树类树种以及以较弱的蒸腾作用度过旱季的相思类树种两大类。旱季蒸腾作用的大小直接影响叶温高低及其叶子的萎蔫与脱落。旱季，马占相思和尾叶桉的蒸腾强度与气温有较紧密的负相关关系，与空气湿度呈较紧密的正相关关系，说明它们受干旱和高温的影响比较大，其它树种则相关性不明显。
Transpiration of some tree species planted in hot and arid valley of Jinsha River has been studied on the spot since 1993.The result shows that those species planted successfully in the area tend to water deficit during drought period,and they can be divided into two groups according to their transpiration.The transpiration intensity of Acacia is lower than that of local species and Eucalyptus and that is characteristic of Acacia through the drought.Leaf temperature is effected remarkably by transpiration intensity and species with transpiration intensity lowing in drought period tent to wither and lose more their leaves.In addition,transpiration intensity of A.mangium and E.urophylla have both negative correlation with air temperature and positive correlation with air humidity that direct the transpiration of two species were restricted,and the other species have not re
