    摘要:

    [目的] 对关中平原城市群生态安全的时空演变进行测度和分析,为该区生态安全保障措施的制定提供科学参考。[方法] 通过构建社会经济—自然生态Lotka-Volterra共生模型及生态安全DPSIR指标体系,以2008—2017年关中平原城市群生态安全状况进行测度,并根据测度结果进行指标回溯分析生态安全问题成因。[结果] ①2008—2017年关中平原城市群整体而言社会经济发展迅猛但生态环境改善状况幅度并不明显;②2009—2016年社会经济子系统受力方向为正,但自然生态子系统受力方向在多个年份表现为负,表明社会经济高速发展而生态环境受到侵害的偏利发展模式在关中平原城市群长期存在。[结论] 产业结构优化步伐缓慢、工业污染、人口扩张对生态承载力造成的压力、快速城镇化对自然资源的侵占等因素已成为阻碍关中平原城市群生态安全提升的重要原因。

    Abstract:

    [Objective] The spatial and temporal evolution of ecological security in Guanzhong plain urban agglomeration was studied in order to provide scientific reference for the formulation of ecological security measures in this area.[Methods] The social economy-natural ecology lotka-volterra symbiosis model and the DPSIR indicator system of ecological security were constructed to measure the ecological security status of Guanzhong plain urban agglomeration from 2008 to 2017. And the causes of ecological security problems were analyzed based on the measurement results.[Results] ① From 2008 to 2017, the social and economic development of Guanzhong plain was rapid, but the improvement of ecological environment was not obvious. ② From 2009 to 2016, the force direction of social and economic subsystems was positive, while that of the natural ecological subsystem was negative in many years, which indicated that the profit-oriented development model with rapid social and economic development and the damage of ecological environment existed for a long time in Guanzhong plain urban agglomeration.[Conclusion] Factors such as the slow pace of industrial structure optimization, industrial pollution, pressure on ecological carrying capacity caused by population expansion, and the occupation of rapid urbanization on natural resources have become important reasons that hinder the improvement of ecological security in Guanzhong plain urban agglomeration.
