英文摘要	Grassland carrying capacity and the number of livestock and wildlife play important roles in maintaining the balance of the grassland ecosystem. In this study, we assessed the grassland-livestock balance between large wild herbivores and livestock. We used the sample line transect method to conduct a survey on population and habitat area of wildlife in Sanjiangyuan National Park, China, from 2016 to 2017 and got detailed information about the population density and distribution of wildlife. The maximum entropy model (MaxEnt) was used to calculate the suitable habitat area of large wild herbivores. In addition, we used a suitable area to calculate the number of wildlife. The results showed that the suitable habitat area of Tibetan wild ass (Equus kiang) and Tibetan gazelle (Procapra picticaudata) were 14,463.7 and 15,306.3 km(2) , respectively, in Maduo County. The number of Tibetan wild ass and Tibetan gazelle was 12,176 and 4,231, respectively. The results indicated that the number of livestock was higher than that of wild herbivores, and overgrazing was the main cause of grassland desertification. However, the wildlife population had little effect on grasslands. The pressure index of livestock on pastures had gradually decreased in recent years. Therefore, we advise to protect the grasslands and control the number of livestock for maintaining local ecological balance and animal husbandry development.
