林木根系单根的生物力学特性
Research of tree roots biomechanical characteristics
摘要
Abstract
Research on fine roots biomechanical characteristics could contribute to understand the relationship between plants and soil, as well play an important role on implementing eco-engineering and bio-engineering methods suitably. Hie goal of this paper was to investigate root tensile strength and root Young's modulus based on roots tensile test, with a case study on two monospecific 17-y-old stands of Robinia pseudoacacia and Platycladus oriettialis grown on slopes in the semiarid Loess Plateau of China. Scale effects were found on biomechanical characteristics of R. Pseudoacacia roots and P. Orientalis roots. Root tensile strength and Young's modulus decrease with root diameter increasing. Both root tensile strength and Young's modulus of R. Pseudoacacia were about two times higher than that of P. Orientalis.关键词
