乔木蒸腾耗水量研究方法述评与展望

参阅了大量国内外有关乔木蒸腾研究方法文献,认为乔木蒸腾量研究方法主要有二大类,即组织器官测定、单木测定;分类对典型研究方法(快速称重法、气孔计法、整株容器称重法、同位素示踪法、热脉冲法、树干热平衡法、热扩散探针法)进行了述评,对比分析了各种方法间的优缺点及其适用范围;展望了乔木蒸腾耗水作用研究方法的应用前景,认为热技术法是未来几年内的主要测定方法。

Referring to a large number of domestic and foreign literature on research methods of tree transpiration,and authors concluded that there are mainly two types of research methods of tree transpiration,which includes determination of tissues and organs,determination of individual tree.This paper reviewed the typical research methods(Quick-weighing method,Porometer method,Whole-tree method,Isotopic tracer method,Heat pulse velocity method,Trunk(segment) heat balance method,Thermal dissipation probe method) fr...
