Abstract: On the basis of reviewing the evaluation of the natural grassland resources of China, the evaluation factors for subtropic grassland resources were screened and properly combined. A mathematical model of three- stage multifactoral evaluation of the natural grassland resources is established through exploiting the relationships among those factors. To verify the accuracy of the model, four types of the resources were evaluated according to the model,and a description of the process of computation in detail is given.
