摘要: 参阅了近年来国内外研究树木蒸腾作用的文献,对研究乔木水分利用的各种代表性方法(整树容器法、称重法、蒸渗仪法、Li1600稳态气孔计法、风调室法、遥感法、水量平衡法、组织热平衡法、热脉冲法、涡动相关法、波文比法、彭曼联合法)的原理、应用技术与方法进行探讨,分析其优缺点,并具体介绍作者目前所采用的热扩散式探针法及遇到的问题与改进,认为热扩散探针法(TDP)是目前研究乔木整树蒸腾作用比较理想的方法。

Abstract: Referring to both domestic and overseas literature on transpiration,some representative methods including whole-tree photometer,weighing,lysimeter,Li-1600 steady state porometer,ventilated chamber,remote sensing,water balance,tissue heat balance,heat pulse velocity,eddy correlation,BREB and Penman Monteith were discussed.The theories and techniques were summarized and the merits and drawbacks were analyzed.The thermal dissipation probe method we adopted presently was concretely introduced with the possible problems in the application and some suggested improvements.At last,the authors concluded that the thermal dissipation probe method was rather perfect to study a whole tree transpiration.
