摘要
Based on amount of field investigation and laboratory analysis, this paper emphasized on the establishment of soil improvement benefit evaluation models. It is pointed out that the benefit evaluation models can be simulated by taking litter biomass, mean diameter of breast high (D), mean height (H) and (D 2H) as independent variables and taking comprehensive benefit evaluation index as dependent variable. The models vary with different independent variables and can be chosen to use according to actual situation.
