• 摘要：基于雾霾胁迫、人口暴露和适应能力，结合遥感数据与统计数据，对2014年中国286个地级及以上城市的雾霾灾害风险进行评价，在此基础上，识别雾霾灾害风险热点区的风险主导因子.结果表明：中国城市雾霾灾害风险整体水平不高且内部差异显著，雾霾灾害风险大体呈"东高西低、北高南低"的空间布局特征.雾霾灾害风险热点区范围涵盖96个城市，占据国土面积92.4万km²，波及人群数量5.9亿.风险主导因子分区方面，适应能力主导区分布在汕头、揭阳、邵阳、娄底、玉林、汕尾、达州、巴中、天水、昭通、潮州和贵港等12个城市；雾霾胁迫主导区分布在郑州、上海、成都、泰州、济南、西安、武汉、鄂州、南京、扬州、天津、无锡、嘉兴、南昌、常州、芜湖、淄博、合肥、镇江、黄石、马鞍山、南通和日照等23个城市，其余61个城市则属于雾霾胁迫-适应能力综合主导区.

• Abstract：A new framework of haze press risk by taking account of haze stress, exposed population and adaptive capacity is presented. Remote sensing data and statistical data were used to evaluate haze press risk of 286 cities in China in 2014. The dominating factors for hotspots of haze press risk were identified. Data suggested that the level of haze press risk in China was not high, but the internal differences between different cities were striking. Haze press risk was generally higher in eastern than western region and northern than southern region. 96 cities were located in hot area of haze press risk, which included 924000 km² land area and 590 million people. Areas dominated by adaptive capacity included 12 cities, namely Shantou, Jieyang, Shaoyang, Loudi, Yulin, Shanwei, Dazhou, Bazhong, Tianshui, Zhaotong, Chaozhou and Guigang; while areas dominated by stress of haze included 23 cities, such as Zhengzhou, Shanghai, Chengdu, Nanjing, Jinan and Xi'an. The remainder 61 cities were dominated by both stress of haze and adaptive capacity.

• Key words：stress of haze  exposed population  adaptive capacity  haze press risk
