摘要
[背景]针对循环系统疾病,此前研究多集中在空气污染、气象因素对它的影响,忽略了城市建成环境会影响循环系统疾病的发生。[目的]探讨中国城市建成环境对循环系统疾病死亡的影响,并量化其影响效果。[方法]以中国17个城市为研究对象,收集2000—2019年循环系统疾病死亡数据和城市建成环境数据(涉及城市绿化、城市用地、城市土地混合、城市道路设施、城市医疗设施)。采用多元线性回归方法分析循环系统疾病死亡率与建成环境的关系,并进行定量分析。深入探究当城市经济发展水平相异、空气质量状况不同的情况下,建成环境会对循环系统疾病死亡产生何种影响。[结果]城市建成环境会对循环系统疾病死亡率造成影响,具有统计学意义(P<0.05)。其中,城市绿地面积以及商业用地面积与循环系统疾病死亡呈负相关关系,其回归系数分别为–0.550、–0.280(P<0.05);相反,城市道路面积的扩大、居住密度的升高以及土地混合度的增大则伴随着循环系统疾病死亡率的升高,其回归系数分别为0.322、0.283、0.176(P<0.05)。当城市经济发展水平较低时,商业用地占比对循环系统疾病的影响表现得更加明显,回归系数为–0.476(P<0.05)。在城市空气污染状况加重时,人均绿化面积与人均道路面积对疾病的影响作用更加突出,回归系数分别为–0.528、0.372(P<0.05)。[结论]城市建成环境与循环系统疾病死亡率存在相关性。人均绿化覆盖面积、商业用地占比与循环系统疾病死亡率呈负相关;人均城市道路面积、居住用地占比、土地混合度与循环系统疾病死亡率呈正相关。
[Background]In view of circulatory diseases,most previous studies focused on the impacts of air pollution and meteorological factors,while ignoring the influence of built environment.[Objective]To investigate and quantify the impact of built environment on circulatory diseases in China.[Methods]Circulatory disease mortality data and built environment data(including urban greenery coverage,urban land use,urban land use mix,urban road facilities and urban medical facilities)of 17 cities in China from 2000 to 2019 were collected.Multiple linear regression was used to analyze which built environment elements had significant influence on circulatory diseases,and to quantify their effects.Furthermore,the changes of built environment indicators on circulatory disease mortality were evaluated under different levels of urban economic development and various air quality.[Results]The built environment affected the mortality of circulatory diseases during the study period(P<0.05).Urban green space and commercial land area were negatively correlated with circulatory disease mortality,and regression coefficients were-0.550 and-0.280,respectively(P<0.05).On the contrary,the increase of urban road area,residential land ratio,and the degree of land use mix were positively associated with circulatory disease mortality,and their regression coefficients were 0.322,0.283,and 0.176,respectively(P<0.05).When the level of urban economic development was low,the impact of commercial land use ratio on circulatory diseases was stronger,and the regression coefficient was-0.476(P<0.05).When urban air pollution worsened,the impacts of per capita green coverage area and per capita urban road area on the disease were more prominent,and the regression coefficients were-0.528 and 0.372,respectively(P<0.05).[Conclusion]There is a significant correlation between urban built environment and mortality of circulatory diseases.To be specific,circulatory disease mortality has a negative correlation with per capita green coverage area and commercial land use ratio,and a positive correlation with per capita urban road area,residential land ratio and degree of land use mix.
