摘　　要：绿地空间格局、局地大气因素、居民呼吸健康是风景园林研究的重要领域,前人大多研究已证实三者中任两者之间存在相关性。分析了三者之间的直接或间接作用机制及影响路径。选取粤港澳大湾区的7个城市,采用表征植被的NDVI、LAI,以及表征景观格局的COHESION等12项绿地空间格局指标,采用气温、风速等4项气候指标和4项大气污染指标表征局地大气因素,采用肺癌发病率、死亡率表征居民呼吸健康,通过多元线性回归模型分析三者之间的相关性,通过偏最小二乘结构方程模型(PLS-SEM)、Bootstrap自助法研究三者之间的中介效应和调节效应。结果表明,绿地空间格局、大气因素、肺癌三者之间在一些指标中存在相关性。中介效应表现为NDVI通过影响空气污染,间接影响肺癌状况,当CONTIG、SHAPE、SHDI指数作为调节变量时,显著增强了风速对发病率的负相关性影响;当气温作为调节变量时,显著增强COHESION、LPI、AI、PLAND指数对发病率的负相关性影响。因此,提升绿地聚集度、形态多样性,不仅影响气温和风速,还能构建出直接或间接路径以降低肺癌发病率和死亡率。Green space patterns,local atmospheric factors,and residents'respiratory health are three essential research areas in Landscape Architecture.Respiratory health is influenced by a multitude of complex factors,including environmental,genetic,lifestyle,and socioeconomic conditions,with green spaces and atmospheric conditions have a particularly impactful influence.The effects of environmental factors on health can be modified through public policy,especially by enhancing respiratory health through the planning and design of green spaces.Most of the research focuses on the correlation between any two of the three,and it has been verified that there exist various correlations such as positive correlation or negative correlation among each pair.This study investigates the comprehension chain relationship between the three,i.e.,the complex interactions between the three directly or indirectly,to explore the mechanism of interaction between the three as well as the path of influence,for providing scientific evidence for the optimization of the green space pattern,the improvement of the atmospheric environment,and the construction of a green space planning that is conducive to the respiratory health of the residents.The research was conducted in the Guangdong-Hong Kong-Macao Greater Bay Area,globally recognized as a pivotal hub for urban development on China's southern coast.Characterized by an urbanization rate of over 80%and a South Asian subtropical monsoon climate,the area is perennially warm and humid.Specifically,the study encompassed seven cities within the Bay Area:Guangzhou,Shenzhen,Zhuhai,Zhongshan,Jiangmen,Hong Kong,and Macao.Twelve indicators,including that representing the coverage degree(NDVI),green biomass(LAI),and the landscape pattern morphology(COHESIN,LPI,SHDI)and other 12 indicators as green space spatial pattern indicators;four climatic indicators,including air temperature,wind speed,precipitation and relative humidity,and four atmospheric pollution indicators,including SO2,NO₂were used to character
