This paper introduces the perspective of “Nature-based Solutions” (NBS) and analyzes the change and driving factors of eco-environmental quality in greenbelt. The findings are as follows. 1) From 2005 to 2020, the eco-environmental quality showed a trend of first decline and then recovery, and a circle spatial pattern was obvious. 2) The change trend of eco-environmental quality in the two greenbelts was different. The eco-environment quality of the first greenbelt was relatively lower, and it continued to decline. The eco-environmental quality of the second greenbelt has stopped falling and rebounded after 2015. 3) As for driving factors, the study confirmed that NBS measures had driving effect on the improvement of eco-environmental quality. Green Infrastructure showed a significant driving effect in both greenbelts, while ecological infrastructure only showed a significant driving effect in the second greenbelt. Since entering the stage of reduction development, the eco-environmental quality of Beijing Greenbelt has improved obviously. In the future, NBS measures can be more targeted to further improve urban eco-environmental quality and the construction of urban green space system.

引入“基于自然的解决方案”(NBS)视角, 借助空间计量模型, 分析绿隔地区的生态环境质量变化及其驱动因素, 得到以下结果: 1) 从生态环境质量变化看, 2005—2020年, 绿隔地区整体上呈现先下降后回升的趋势, 空间上圈层格局明显; 2) 两道绿隔地区的生态环境质量变化趋势不同, 第一道绿隔地区相对更低, 且一直延续下降趋势, 第二道绿隔地区2015年后止降回升; 3) 从驱动因素看, NBS措施对绿隔地区生态环境质量改善具有驱动作用, 其中绿色基础设施在两道绿隔地区都表现出显著的驱动作用, 而生态基础设施仅在第二道绿隔地区表现出显著的驱动作用。北京市进入减量发展新阶段以来, 绿隔地区的生态环境质量明显改善。未来可以更有针对性地应用NBS措施, 进一步提升城市生态环境质量, 完善城市绿色空间体系建设。
