[A review on heat-wave early warning based on population health risk].

Global warming has caused frequent heat waves worldwide. In order to respond to heat waves and enhance the public's protection abilities, Europe, the United States and other countries have extensively carried out research on heat-health early warning, and initially achieved good health benefits based on a heat-health early warning system. However, the research on heat-health early warning is still limited in China, especially on health risks at the population level. Based on evidence-based thinking, our study combs the research progress of heat-health early warning from four aspects: early warning indicators, early warning models, early warning thresholds, and early warning ranks, and clarifies the key points of the construction of heat-health early warning models and rank schemes, in order to provide early warning technology for the rapid development of national heat-heath early warning in China.全球变暖的长期趋势将直接导致世界各国高温热浪频发。为了应对高温热浪、增强公众防护能力，欧美等国广泛开展高温热浪健康风险预警研究，并基于人群健康风险建立分级预警系统，初步取得较好的健康收益。然而，目前我国高温热浪健康风险预警研究处于起步阶段，以人群健康风险为核心构建的高温热浪预警研究相对较少。本研究从预警指标、预警模型、预警触发值、预警分级等四方面梳理国内外高温热浪健康风险预警研究进展，进而明晰高温热浪健康风险预警模型和预警分级方案构建要点，以期为我国大力发展高温热浪健康防护行动奠定预警技术储备。.
