D ynamci Analysis of Ec ological Footprint and Ecological Carrying Capacity in Alpine Va lley Areas-A Case Study of Diqing Tibetan Autonomous Prefecture in Yunnan Province
摘要
Abstract
To study the application of the ecological footprint model in alpine valley areas and provide theoretical basis for the sustainable de-velopment of Diqing Tibetan Autonomous Prefecture,the ecological footprint and ecological carryingcapacity in Diqing Tibetan Autonomous Pre-fecture in Yunnan Province during 2005-2014 were calculated and analyzed based on the Calculation Methodology for the National Footprint Accounts (the2010 Edition).The results showed that in Diqing Tibetan Autonomous Prefecture during 2005-2014, ecological footprint per capita increased from 0.825 3 gha in 2005 to 1.251 7 gha in 2014;ecological carrying capacityper capital declined from 0.945 8 gha in 2005 to 0.467 8 gha in 2014; ecological balance gradually changed from slight ecological surplus to ecological deficit which increased obviously, and 2.66times of ecological carrying capacity in Diqing was needed to support the economic development ; the contribution of carbon uptake land to total ecological footprint increased quickly, which was the dominant factor resulting in ecological deficit;annual growth rate of ecologi-cal efficiency in Diqing calculated based on ecological footprint was far lower than that of GDP in Diqing .关键词
