摘要:
老年友好城市和健康城市的建设需要明晰蓝绿空间对老年心理健康的效益。针对既有文献在指标选取和空间跨度方面的单维性,利用区分个体和邻域层级的分层线性模型和多层结构方程模型,从城市蓝绿空间的质量(内部环境特征、景观格局指数)与数量(可视性、可得性)维度系统比较对老年心理健康作用的差异,并从活动能力、环境感知和社会凝聚的中介路径,探寻造成差异的内在机制,同时在多空间尺度下检验结论的稳健性。研究结果表明绿色空间的可视性相比可得性有更高的老年心理健康效益;多样化的中介路径使得蓝绿空间质量维度指标与老年心理健康的联系更为显著;蓝绿空间与老年心理健康的关系及中介效应呈现出空间圈层下的规律性分异特征。基于上述结果提出老年心理健康导向的城市蓝绿空间规划建议。

Abstract:
The construction of age-friendly and healthy cities needs to clarify the benefits of blue-green space on the elderly’s mental health. In light of the one-dimensionality of existing literature in terms of indicator selection and spatial scale, this research systematically compares the differences between the qualitative dimension (internal environment characteristics, and landscape pattern index) and the quantitative dimension (visibility and availability) of blue-green space in their effects on the elderly’s mental health, explores the intrinsic causes of such differences by examining the mediating effects of activity capability, environmental perception and social cohesion, and verifies the robustness of conclusions at multiple spatial scales. Research results show that the visibility of green space can bring more benefits to the elderly’s mental health than the availability thereof; diverse mediating pathways can significantly strengthen the association between the qualitative dimension of blue-green space and the elderly’s mental health; the association between blue-green space and the elderly’s mental health and relevant mediating effects show regular variation characteristics under the multi-spatial circles. Based on the conclusions above, the research proposes suggestions for planning urban blue-green space oriented at the elderly’s mental health.
