A method for measuring biomass of tree-roots by ground-penetrating radar

摘要

The invention provides a method for measuring the biomass of plant underground roots by using ground penetrating radar. The method comprises the following steps of: obtaining the specific position of the plant underground roots to be measured through the scanning of the ground penetrating radar, and generating corresponding reflected waveform scanning data; selecting an oscillogram of a reflected wave passing over the central position of the plant underground roots to be measured; extracting five waveform parameters from the oscillogram according the oscillogram; and establishing three comprehensive indexes according to the five waveform parameters so as to obtain the biomass of the measured plant underground roots. Therefore, the biomass of the plant underground roots can be accurately and quantitatively measured through the ground penetrating radar; and the obtained measuring result has high relevance to the actual biomass of the plant underground roots.
