%X This paper explores further the precision estimate of biomass by making improvement on the way biomass models are constructed and parameters identified. To that end,a unified model is set up to estimate the biomass by constructing a group of product-type base of p-dimensional continuous function space through Chebyshev polynomial combination. This model has the following characteristics:(1) It can overcome the experientialism,instability,limited applicability and poor adaptability to biomass-affecting facto...
