Abstract

Abstract: Maqu County is an important indicator region for the stability and maintenance of the Qinghai-Tibet Plateau and includes the upper reaches of the Yellow River. It is of great significance to study the sustainability of its ecological environment and social and economic development. The ecological footprint model was applied to study the changes in per capita ecological footprint, ecological carrying capacity, ecological deficit and sustainable development index of Maqu County from 2007 to 2016. The results indicate that the per capita ecological footprint of the study area increased significantly in the past 10 years, from 4.26 ha in 2007 to 5.91 ha in 2016, an increase of 38.73%. Pasture accounted for 98.83% of the per capita ecological footprint of the region, ecological carrying capacity trended downward from 3.74 ha in 2007 to 3.04 ha in 2016, with a drop of 18.72%. In this region, all 10 years for which data were analyzed showed an ecological deficit, and the overall ecological security situation was very weak and unsustainable. Pasture is the main resource for consumption in ecological footprint evaluation in Maqu County, and the imbalance between demand for pasture forage for consumption and sustainable supply, with resulting pasture degradation, is strongly evident. Therefore the protection of grassland through adoption of ecologically sustainable practice in this area should become apriority.

Key words: Maqu County, ecological footprint, ecological carrying capacity, ecological deficit, sustainable development
