The degradation of alpine grassland on the Qinghai-Tibet Plateau severely threatens regional ecological security， creating an urgent need for restoration techniques that balance rapid vegetation recovery with long-term functional enhancement. This study employed a field-controlled experiment to systematically investigate the effects of biocrust addition， non-woven fabric covering， and their combined treatment on the ecological restoration of degraded alpine grassland. Sixteen plots were established in Gangcha County， Qinghai Province， using a randomized block design. Vegetation characteristics， soil physicochemical properties， and erosion resistance were measured. The results showed that： （1） The non-woven fabric treatment rapidly restored vegetation， and significantly increased aboveground dry matter and vegetation coverage by 375.5% and 107.6%， respectively， compared to the control. （2） The biocrust treatment facilitated long-term ecological function recovery， and enhanced plant diversity and moss crust coverage by 40.4% and 863.6%， respectively. It also significantly increased soil organic matter and total nitrogen content in the crust layer by 20.8% and 13.1%. （3） The comprehensive treatment exhibited the strongest synergistic effect， reducing the soil erosion modulus by 83.1% compared to the control group. In conclusion， non-woven fabric covering is suitable for rapid vegetation recovery， biocrust addition promotes long-term soil improvement and biodiversity， and their combination offers synergistic advantages in enhancing nutrient availability and controlling soil erosion. This study provides an optimized multi-objective technical approach for restoring degraded alpine grassland.
