摘 要：
对树木个体蒸腾耗水的研究方法较多,如热技术法、同位素示踪法、风调室法、盆栽称重法、整树容器法和蒸渗仪法等。其中热技术法中的热扩散具有保持树木在自然生长条件下基本不破坏树木正常生长状况,可以连续测定树干液流的优点,而且易于野外操作及远程下载数据。目前利用热扩散探针(TDP)茎流计测量树干液流开始向精准化、普及化和系统化的方向发展。

摘 要：
There were many methods to study water transpiration of individual tree,such as heat and Technology method,tracer isotopes,wind-room,potted plants weighing method,the whole tree container way and lysimeter way.Heat and technology method had the advantage of maintaining the basic conditions of normal growth of trees in the course of continuously testing the sap flow of tree trunks.The operation outdoors and downloading data was easy.TDP was being measured accurately,universally and systematically.
