Studies of Evaluation Models on Soil Improve ment Benefit of Water and Soil Conservation Forest
Based on amount of field investigation and laborat ory analysis, this pa per emphasized on the establishment of soil improvement benefit evaluation model s. It is pointed out that the benefit evaluation models can be simulated by taki ng litter biomass, mean diameter of breast-high (D), mean h eight (H) and (D2H) as in dependent variables and taking comprehensive benefit evaluation index as depende nt variable. The models vary with different independent variables and can be cho sen to use according to actual situation.
