摘要:
[目的] 开展生态环境与贫困的耦合分析,为生态脆弱区的精准扶贫和可持续发展提供科学建议。[方法] 以典型生态脆弱区——四川省藏区为例,采用耦合度与耦合协调度模型,对2008—2017年四川省藏区生态环境与贫困耦合状况进行动态定量分析和测度。[结果] ①2008—2017年四川省藏区生态环境与贫困耦合发展呈现较低水平的平稳态势,耦合度数值维持在0.072 2~0.706 3之间,且表现逐年上升的变化趋势,2011年则波动下降。②2008—2017年四川省藏区生态环境指数呈逐年递增态势,数值维持在0.0295~1.000 0之间。且贫困指数也呈逐年增加趋势,数值维持在0.006 3~0.995 4之间,但2011年则波动下降。③除2011年波动下降外,2008—2017年四川省藏区生态环境与贫困耦合协调度呈逐年增加趋势,耦合协调度维持在0.035 9~0.839 4之间,且耦合协调度与耦合度变化趋势基本一致。④2008—2017年四川省藏区生态环境与贫困耦合协调度呈现低水平耦合发展、耦合过渡提升至高水平耦合协调贫困滞后3个不同阶段。[结论] 未来四川省藏区应以生态保护与贫困减缓为关键点和突破点,以实现生态脆弱区社会经济和环境系统的可持续发展。

Abstract:
[Objective] The relationship of the ecological environment and poverty was studied to provide scientific reference for the targeted poverty alleviation and sustainable development in ecologically fragile areas.[Methods] A typical ecologically fragile area, the Tibetan area in Sichuan Province, was taken as the study area. The coupling status of the ecological environment and poverty in the Sichuan Tibetan area was measured and analyzed by using a coupling degree model and coordination degree model from 2008 to 2017.[Results] ① The coupled development of the ecological environment and poverty in the Tibetan area was relatively stable at a low level from 2008 to 2017, and the coupling degree was mostly between 0.072 2 and 0.706 3. The variation trend of the coupling degree increased annually, but there were fluctuations in 2011. ② From 2008 to 2017, the ecological environment index of the Tibetan area showed an increasing trend annually, with a value between 0.009 5 and 1.000 0. The poverty index also showed an increasing trend annually, with a value between 0.006 3 and 0.995 4, but there was a fluctuation in 2011. ③ In addition to the fluctuation in 2011, the coupling coordination degree of the ecological environment and poverty in the Tibetan area increased annually from 2008 to 2017, and the value was between 0.035 9 and 0.839 4. The variation trends of coupling degrees and coordination degrees were similar from 2008 to 2017. ④ From 2008 to 2017, the coupling and coordination degree between the ecological environment and poverty of the Tibetan area had three different stages:low-level coupling development, coupling transition, and high-level coupling coordination of poverty lag.[Conclusion] In the future, ecological protection and poverty alleviation should be regarded as essential in the Tibetan area of Sichuan Province to achieve sustainable development of socio-economic and environment system in this ecologically fragile region.
