摘要
植物的截留观测可以分为林冠截留观测与地面枯枝落叶层截留观测两方面,对林外总降雨量、林下透落雨量、枯落物截留量、树干茎流量以及植被特征等各具体相关观测项目的观测方法进行了较为全面的总结,从中可以看出,各项目的观测方法、观测点布设、与截留相关的植被参数估计方法等较为多样化,没有统一、标准的方法.在此基础上,提出了减小观测误差的相关建议.
The plant interception measurement can be roughly categorized into the canopy interception measurement and the litter interception measurement.A comprehensive review on experimental studies of the gross rainfall,thoughfall,litter interception,stemflow and plant characteristics is presented.It is shown that the methods for the rainfall interception measurement are diversified in the layout of their instruments and the procedures for estimating parameters.There are no united and standard methods.On such a basis,some suggestions for reducing measurement errors are proposed.
