介绍了热扩散探针方法(TDP)测定树干液流的基本原理,并综述了热扩散探针法在树木单株液流与耗水特征及其影响因素、林分蒸腾耗水量估计等研究中的应用现状,最后阐述了树干液流研究中存在的问题及展望。
The principle of the Thermal Dissipation Probe (TDP) method, which was used to measure sap flow of the trees, was in- troduced in this paper. The sap flow and water consumption for transpiration of the whole - tree, measured by the TDP method, were reviewed. Also, the factors which affect tree transpiration and the estimation of the water consumption of forest stand were overviewed. Finally, the paper described the problems and the prospects of the TDP method in the study of sap flow.
