文章进一步揭示了林地植被平抑这种动态效应,而裸地则响应于温度变化;这种不同植被系统下的动态差异在解释岩溶沉积记录和讨论岩溶作用与碳循环的关系时值得充分注意。

The results show that whether the stiffness profiles are smoothly varying or layered, the fundamental mode dominates the surface wave field and the effective phase velocity approaches to the phase velocity of the mode in far field for the regular profiles. For the irregular profiles, the higher modes have a significant influence on the surface wave field. The intensity and the frequency range of the influence are related to variation of the profile stiffness.
