摘要/Abstract

摘要： 着重介绍了水力结构及其各种参数 (即导水率Kh、比导率Ks、叶比导率LSC、胡伯尔值Hv以及水容量C)的生理意义、树木和其它木本植物的水力结构格局以及树木水力结构研究发展趋势,并试图从机理上阐述树木水力结构和抗旱性之间的关系.

关键词: 水力结构, 参数, 木本植物

Abstract: This paper introduced with emphasis the physiological meaning of hydraulic architecture and its parameters,e.g.,hydraulic conductivity(Kh),specific conductivity(Ks),leaf specific conductivity(LSC),Huber value(Hv) and water storage capacitance(C),the hydraulic architecture patterns of woods and woody plants,and the developmental trend in their research.The relationship between the hydraulic archteciture of woody plants and their drought resistance was tried to be expounded in mechanism.

Key words: Hydraulic architecture, Parameter, Woody plants
