Objective The application benefits of different restoration and management measures in degraded grasslands were comprehensively evaluated, and the technical and application conditions for the management of natural degraded grasslands in the Bashang area of northern Hebei Province were analyzed, in order to provide technical and application experience for the ecological management of grasslands in the Bashang area, and to support the coordinated development of the ecological environment and rural revitalization. Methods From 2022 to 2024, experimental plots were established in Xinhua village in Baituyao Township and Lvyuan Village in Jiuliancheng Town, Guyuan County, with five natural grasslands located in Weichang, Fengning, Zhangbei, Kangbao, and Shangyi counties as control plots. Several intervention measures were implemented, including enclosure + root cutting, enclosure + fertilization, enclosure + grass planting, and enclosure only. Indicators such as community characteristics, surface characteristics, grass yield, and palatability of each plot were systematically investigated and analyzed. Results ① Within two years, the quality of degraded grasslands was significantly improved by enclosure + grass planting measures, with greater effectiveness observed in degraded typical grasslands compared to degraded meadow grasslands. The annual dry weight of grass yield increased by 54.25% and 48.18% in the degraded typical grasslands and degraded meadow grasslands under this treatment, respectively, while the annual dry weight of palatable forage grass increased by 2.10% and 1.20%, respectively. ② Enclosure + fertilization measures effectively increased vegetation coverage and reduced the proportion of bare ground, with vegetation coverage increasing by 1.20% and 1.60% annually, and bare ground decreasing by 0.60% and 0.80% annually in degraded typical grasslands and degraded meadow grasslands under this treatment. ③ Enclosure + root cutting measures could improve the plant community diversity to some extent, but the effectiveness varied by location. ④ Enclosure only was the least effective among the four measures, but still performed better than the control plots. Conclusion Compared with natural restoration, human intervention can significantly improve the plant community characteristics and productivity in the short term, but the overall impact on community species diversity is not significant. For the slightly degraded typical grasslands in the Bashang area of northern Hebei with production demands, the recommended order of restoration measures is enclosure + grass planting, enclosure + fertilization, and enclosure + root cutting. For grasslands without production demands, the measure of enclosure only is recommended. For degraded meadow grasslands with tourism value, the enclosure + fertilization measure is recommended to improve the community characteristics and enhance the landscape aesthetics.
