摘要
回顾了茎流计及其应用发展历程。茎流计测定植物液流速率的工作原理主要有4种:热脉冲法、热平衡法、热扩散法和激光热脉冲法。通过SCI数据库和中国知网数据库查阅统计茎流计在国内外应用情况,介绍几种方法的应用成果。通过对现有研究成果和应用前景分析认为,热平衡法与热扩散方法将成为未来几年研究树木液流的重要测算方法,而鉴于激光热脉冲法的优越性,估计未来会有很广阔的应用前景。
The paper reviewed the development and application of sap flow gauge.There are four different principles of sap flow gauge to measure sap flow rate of plants which are heat pulse velocity method,stem heat balance method,thermal dissipation method and laser heat pulse method.By information searching in SCI database and national knowledge infrastructure database of China,the paper made a summary about the application of sap flow gauge.Based on the analysis for research results and application progress,the stem heat balance and the thermal dissipation method will become the important measuring methods in the near future.While in view of the superiority of laser heat pulse method,it will heve a good prospect in the future.
