| Abstract: | Taking Nitraria tangutorum shrub at the outside of the Minqin oasis of Gansu Province as an example,easily determined characters of N.tangutorum shrub in sand dune,such as length(x1),width(x2),and height(x3) were chosed to establish regression equation.With the method of linear regression,5 forecast models were set up to facilitate the biomass of shrub dune.These models are as fallows: Total biomass:y=0.95+1.354x 1-5.123x 2+37.52x 3 Biomass on the ground:y=-0.278+0.32x 1-1.094x 2+8.951x 3 Biomass under the ground:y=-0.672+1.034x 1-4.029x 2+28.574x 3 Biomass at internal dune:y=-0.432+0.863x 1-4.02x 2+28.204x 3 Biomass in the clay:y=-0.24+0.171x 1-0.01x 2+0.369x 3 |
