摘要
经济发展如何破解生态环境资源约束是可持续发展的重要研究议题。为探究生态移民区生态可持续发展能力变化情况,基于生态足迹法,构建了生态移民区可持续发展能力评价指标体系,对2000—2020年宁夏生态移民区生态可持续发展能力进行评估。在此基础上,采用脱钩模型分析了生态环境压力与经济发展脱钩关系。结果表明:(1)迁入区(红寺堡区)与迁出区(西吉县、隆德县、同心县)生态盈余呈下降趋势。红寺堡区生态盈余从2013年的0.730 hm~2·人~(-1)下降到2020年的-0.054 hm~2·人~(-1)。2000—2020年西吉县生态盈余从1.226 hm~2·人~(-1)下降到0.963 hm~2·人~(-1);隆德县生态盈余从0.760 hm~2·人~(-1)下降到-0.113 hm~2·人~(-1);同心县生态盈余从0.755 hm~2·人~(-1)下降到0.347 hm~2·人~(-1)。(2)迁入区生态可持续发展能力下降,迁出区生态可持续发展能力整体较高,但内部发展不均衡。迁入区生态可持续发展能力综合指数呈“W”变动趋势。从2013年-0.012降低到2020年-0.325。迁出区中西吉县和同心县生态可持续发展能力提高,隆德县生态可持续发展能力降低。2000—2020年西吉县生态可持续发展能力综合指数从-0.324上升到0.037;同心县生态可持续发展能力综合指数从-0.552上升到-0.125;隆德县生态可持续发展能力综合指数从-0.029下降到-0.375。(3)迁入区生态环境与经济发展未实现协调发展,迁出区经济增长与生态压力脱钩状态呈现区域性差异。因此,提出了坚持生态保护优先,走绿色发展之路、促进生态修复,走科技创新治理之路、优化资源配置,走协调发展之路的建议。
How economic development can break ecological constraints is an important research topic for sus-tainable development.To explore the changes in ecologically sustainable development capacity in ecological mi-gration areas,the authors used the ecological footprint method to construct an index for evaluating the sustainable development capacity of ecological migrants and used it to evaluate the sustainable development capacity of the Ningxia ecological migrant areas,northwest China from 2000 to 2020.A decoupling model was also used to ana-lyze the relationship between ecological and environmental pressure and economic development.The research re-sults show the following:(1)The ecological surplus of the migrated-in area(Hongsibu District)and the migrated-out area(Xiji County,Longde County,and Tongxin County)showed a decreasing trend.The ecological surplus of Hongsibu District decreased from 0.730 hm2·cap-1 in 2013 to-0.054 hm2·cap-1 in 2020.From 2000 to 2020,the ecological surplus of Xiji County declined from 1.226 hm2·cap-1 to 0.963 hm2·cap-1.The ecological surplus of Longde County declined from 0.760 hm2·cap-1to-0.113 hm2·cap-1.The ecological surplus of Tongxin County de-clined from 0.755 hm2·cap-1 to 0.347 hm2·cap-1.(2)The ecological sustainability of the in-migration area de-creased,while the ecological sustainability of the out-migration area was high,but the development is uneven within the region.The relocation area’s ecological sustainability index shows a“W”trend.The ecological sus-tainability index decreased from-0.012 in 2013 to-0.325 in 2020.As a result,the ecological sustainability of Xi-ji and Tongxin counties in the migrated-out area is improved,and the ecological sustainability of Longde County is reduced.From 2000 to 2020,the ecological sustainability index of Xiji County increased from-0.324 to 0.037,the ecological sustainability index of Tongxin County increased from-0.552 to-0.125,and the ecological sus-tainability index of Longde County decreased from-0.029 to-0.375.(3)The ecologica
