2007—2011年高温对哈尔滨市区人口死亡的影响

目的探讨高温对哈尔滨市区人口死亡的影响。方法分析哈尔滨市近5年来的气候特点，以32~C为临界点，区分“热日”、“非热日”。在此基础上，分析哈尔滨市区2007—2011年夏季（6—8月份）日最高温度与总死亡数、年龄、性别死亡数的关系，并对人121死亡的影响进行探讨。结果哈尔滨夏季最高气温多出现在6月份，最高达37．8℃。当气温超过29℃以上时，死亡数随温度的升高而增加，“热日”与“非热日”死亡数之比为1．23：1（F=6．91，P=0．0303）；老年人对热更敏感。结论哈尔滨的高温天气对人口死亡有显著影响。

Impact of high temperature on population death in urban Harbin 2007 -2011

Objective To explore the relationship between the high temperature and population death in urban Har- bin. Methods The climate characteristics of Harbin in recent 5 years were analyzed and ＂hot day＂ and ＂non hot day＂ were distinguished as 32℃ critical point. The impact of daily highest temperature was analyzed from 2007 to 2011 （from June to August） on daily death in summer based on the study of the climate characteristic of Harbin, then the relationship between daily highest temperature and total death, age - specific, sex - specific death was studied. Results In summer, the highest temperature which could reach to 37.8℃ , emerged mostly in June, and when the highest temperature was high- er than 29℃, mortality increased as the temperature increasing, the mortality ratio of ＂hot day＂ and ＂non hot day＂ was 1.23：1 （ F = 6. 91,P = 0. 0303 ） ; The aged was more sensitive to heat . Conclusion The high temperature may obviously increase mortality in Harbin.
