Abstract: It is an important way to improve management of nature reserves to assess effectiveness of their management. Based on the evaluation of 22 national nature reserves in Inner Mongolian Autonomous Region and proceeding from the ten evaluation indices that are involved in scoring in evaluation, holistic featureS, regional differentiation and factors affecting effective management of nature reserves were analyzed. In general, the management of the national nature reserves in inner Mongolian could be sorted into the level of “good”, scoring 79 on average, which means it still has much room from improvement. The management level of the national nature reserves in west Inner Mongolian was slightly lower than that of those in east Inner Mongolian, but the difference between them was not significant. For promoting the management level, the priority task is to strengthen daily routine management of the reserves. In the mean time, capacity building, institutional restructuring, staffing, dynamics of protected objects, drafting and executing of plans, and infrastructural construction are all important factors that may have extremely significant impacts on effective management of the nature reserves.

Key words: national nature reserve, effective management, evaluation, inner Mongolian autonomous region
