本文提出伪茎流系数概念,并说明了它与茎流系数的本质差别以及以往无意中用它来代替茎流系数作茎流与树木特征之间关系研究的不可行性。研究表明,树皮特征及其湿润状况对茎流的影响较大;试验样地年茎流量为16.6mm,约占年降雨量的1.1%。
In this paper, the concept of pseudostem flow coefficient is proposed, and the essential difference between it and the flow coefficient is explained. In the past, it was unfeasible to use it instead of the flow coefficient to study the relationship between the flow of stem and the characteristics of the tree. Studies have shown that the bark characteristics and wet conditions on stem flow greater impact; experimental plot annual stem flow of 16.6mm, accounting for about 1.1% of annual rainfall.
