As an important part of natural resources, grassland resources not only play a role as the means of production in the process of rural revitalization and development in China, but also have key ecological and production values. In the context of implementing the national inventory of natural resources, land right confirmation, and marketization of compensated use, the original grassland classification system can no longer fully meet the requirements of the current form of development. Therefore, based on the existing grassland grading systems and by integrating the natural, economic, and social attributes of grasslands and considering the availability and operability of data for evaluation indicators, this study reconstructed the evaluation indices and indicators of grassland grading and classification. According to the weighted scores of each indicator, five grassland grades were divided, and five grassland classes under each grade were defined. Three villages in Inner Mongolia were evaluated by this method. This study aimed to reflect the real-time nature of grading, provide a theoretical basis for grassland utilization and protection, and provide a reference for further development of grassland classification and grading system and grassland resource pricing system.
