Abstract：Vegetation habitatsare highly susceptible to the mining activities which lead to the deterioration of grassland ecology in high-altitude mining areas. Constructing a green ecology with new technologies is an important engineering task that urgently needs to be addressed.This study used bionic turf as the experimental material for the test group，and a control group did not use bionic turf materials.By evaluating growth indicators such as plant height，root length，dry weight，fresh weight，coverage，and tiler number，as well as soil and microbial-related indicators，the study revealed the impacts of bionic turf on the ecological restoration of the cold mining areas in the Qinghai-Xizang Plateau.Theresults showed thatthe ecological restoration technique of bionic grass mat efectively promoted plant growth，and plant height，tiller number，vegetation cover，root length and plant fresh dry weight increased by 378.9% ， 852.9% ， 219.9% ， 229.8% ，397.4 and 218.0% ， respectively，compared with that in the control group（ P<0.05） ；the soil nutrient content （AN，AP and SOC）were significantly higher than those in the control group；the bionic grass mats efectively increased the number of Bacteroidota dominant bacteria and Ascomycota phylum.Based on the comprehensive analysis of the restoration efects and economic benefits of the plateau mining area，the bionic grass mat effctively promoted thegrowth of vegetation，reduced the economic cost，and had good ecological and economic benefits for the eco logical restoration of plateau mines.
