[Objective]The desert Tamarisk chinensis characteristics of biomass in Tarim River were studied.[Method]The study was conducted research on biomass of desert Tamarisk chinensis,and samples collected under different coverage,the aboveground,underground biomass distribution were analyzed. [Result](1) Tamarisk chinensis aboveground biomass increases with increasing coverage increases.(2) With standard strains of aboveground biomass of Tamarisk chinensis as x,underground biomass for y,the allometric equation wa...
