THE STUDY OF SUSTAINABLE DEVELOPMENT OF ALPINE PASTORAL REGION IN EASTERN TIBETAN PLATEAU BASED ON THE MODEL OF EMERGY ECOLOGICAL FOOTPRINT

Sustainable development has become a shared goal of all countries in the world. The assessment of regional sustainability is becoming an important theoretical basis for making policy. Based on emergy theory, the modified emergy ecological footprint model has been used to analyze the sustainable development status of Gannan Tibetan Autonomous Prefecture from 2005 to 2013. The results indicated that (1)The livestock products accounted for the largest proportion of the ecological footprint in the study area. (2)The emergy ecological footprint per capita has increased from 2005 to 2013 in the study area, meanwhile the emergy carrying capacity per capita has fluctuated. (3)The ecological footprint index of Gannan showed a decreasing trend, the region was in unsustainable development status during the study period. (4)The ecological footprint of per ten thousand yuan GDP (Gross Domestic Product) of Gannan reduced rapidly, which revealed that the resource utilization efficiency improved. Based on above findings, the future sustainable development strategy of Gannan has been discussed. So we can provide useful methods and practical references for the sustainable development decision-making of the majority of alpine pastoral.
