| The grasslands in Zhaotong City are mainly mountainous meadows, with fragile grassland ecosystems and low management and construction capabilities, making it difficult to restore degraded grasslands. The current grassland area in Zhaotong City is 116 079.33 hm2, of which 6 992.10 hm2 was degraded grassland, accounting for 6.02% of the total grassland area. The degraded grassland is mainly characterized by mild degradation, with an area of 4 221.00 hm2. The reasons for grassland degradation include human factors, invasion of harmful organisms, fragile ecological environment, and climate factors. This paper provided measures for the restoration of degraded grasslands, including near natural restoration, artificial promotion restoration, artificial grassland planting, and comprehensive restoration, and suggested to accelerate the construction of grass seed bases, standardize grassland management, prioritize ecology, and adapt to local conditions. |
