摘　　要：Enhancing green space exposure is a crucial strategy for proactively intervening in public health from an upstream perspective.However,the distribution of green spaces in urban areas is often uneven,leading to issues such as“green inequity.”This study aims to systematically assess the level of green space exposure at overhead and eye levels,analyze the geographical and social equity of green space exposure,and propose planning and regulatory strategies.Focusing on Nanjing as the study area,the research team first constructed a green space exposure assessment system based on the composition and configuration of urban green spaces at the overhead level,and the quantity and perceived quality of street green space at the eye level,assessing the geographical equity of green space exposure.Next,by selecting housing price as a socio-economic indicator,the research used various spatial regression models to analyze the spatial correlation between green space exposure and housing price,evaluating the social equity of green space exposure.The research finds 1)significant imbalances in both the geographical and social equity of green space exposure within the study area;2)the spatial correlation between eye-level green space exposure indicators and housing price ranges from 0.08 to 0.29,generally higher than that at overhead level(ranging from 0.02 to 0.13);3)significant heterogeneity in the spatial correlation between green space exposure and housing price,with people in higher-priced housing being more likely to benefit from green space services.The results can accurately identify blind spots in green space exposure and imbalance areas between green space supply and socio-economic status,providing guidance for“scientific greening,”and further promoting empirical studies in Exposure Ecology.提升绿地暴露水平是上游主动式干预公众健康的重要抓手。然而,绿地在城市空间中常呈现不均衡分布,引发了针对“绿色公平”等议题的讨论。本研究旨在基于鸟瞰-目视视角系统地评估绿地暴露水平,剖析绿地暴露的地理-社会公平性分异并提出规划调控策略。本文以南京市中心城区为研究区域,首先从鸟瞰视角下的绿地组成和配置及目视视角下的绿量和街景感知质量构建绿地暴露评估体系,评估绿地暴露的地理公平性。其次,选取房价作为社会经济指标,使用空间回归模型分析绿地暴露与房价水平的空间关联,评估绿地暴露的社会公平性。研究发现:1)研究区域内绿地暴露在地理公平性和社会公平性层面均存在显著失衡现象;2)目视视角下的绿地暴露指标与房价水平的空间自相关性为0.08~0.29,普遍高于鸟瞰视角(0.02~0.13);3)绿地暴露与房价的空间关联存在显著分异特征,高房价群体更易享受绿地服务。研究成果精准识别了绿地暴露盲区,以及绿地供给与社会经济水平的失衡区域,为科学“增绿”提供了有效指引,也可以进一步促进暴露生态学理论的实证研究。
