After briefly reviewing an appraisal of natural grassland of the Northern China, we made an attempt to apply a new mathematical method to grassland utilization and management. We turned our attention to those factors that can play an important part in an appraisal of grassland resources. A fuzzy mathematical model of multifactorial tri‐stage appraisal of grassland resources is proposed in this paper. This is the first report in which such a mathematical model is applied to the appraisal of natural grasslands. To verify the practical value of the model, we appraised three types of grassland as examples and the description of the computing process is given in detail. The present study proves that the model was highly accurate and is suitable for economic‐technological appraisals for natural grassland.
