摘要:
[目的]定量分析2010-2015年内福建省福州市生态环境压力与经济发展现状,判别经济发展与资源消耗、环境污染和生态环境压力综合状况的脱钩耦合关系,揭示该区生态经济系统脱钩耦合特征。[方法]从生态环境压力与经济发展脱钩耦合关系理论体系构建出发,综合运用生态足迹模型、多因素综合评价法和改良脱钩耦合模型。[结果]①支撑福州市区域发展所需的额外生态承载力由2010年的2.89倍增长到2015年的3.37倍,足迹账户内部的贡献率大小依次为碳吸收地 > 农地 > 建成地 > 林地 > 草地 > 水域;②3组脱钩耦合要素在各时段范围内的脱钩耦合类型均为脱钩型,未出现临界状态和耦合型。[结论]①福州市生态环境压力状况总体较大,生态透支程度较高,在生态环境压力的内部结构中环境污染压力比重高于资源消耗压力并居于主体地位;②福州市经济发展方式尚处于可持续的范围中,但3组脱钩耦合要素的脱钩耦合关系呈现出差异化的时序演化特征。

Abstract:
[Objective] To study the relationships between economic development and resource consumption, environmental pollution and eco-environment pressure, in order to reveal the decoupling characteristics of eco-economic system of Fuzhou City, Fujian Province during 2010-2015. [Methods] Ecological footprint model, multi-factor comprehensive evaluation method and improved de-coupling model was used to analyze the eco-environment pressure and economy development status. [Results] ① The additional ecological carrying capacity required to support the regional development increased from 2.89 times in 2010 to 3.37 times in 2015, and the internal contribution rate of the footprint account was ranked as: carbon footprint > cropland > built-up land > forest land > grazing land > fishing grounds. ② The types of the three decoupling coupling elements in the range of every stages were all decoupling type, and there was no critical state or coupling type. [Conclusion] ① The overall eco-environment pressure in Fuzhou City is relatively large, and the dominant pressure in the internal structure of ecological environment is the environmental pollution pressure. ② The development approach in Fuzhou City is still in a sustainable scope, but the decoupling relationship of three decoupled element groups present different temporal evolution feature.
