兰州市呼吸道疾病与沙尘天气关系的分析

The Relationship between Respiratory System Disease and the Sandstorm Weather in Lanzhou

利用 1996～ 1998年春季兰州市某医院呼吸道门诊逐日病例资料和同期甘肃河西 19站沙尘暴、扬沙及兰州站浮尘逐日资料 ,对兰州市呼吸道疾病发病人数与沙尘天气的关系进行了分析。分析结果表明 ,两者之间呈显著的正相关 ,当甘肃河西发生沙尘暴、扬沙天气或兰州出现浮尘天气且无明显降水后的 1～ 2d ,兰州市呼吸道疾病呈现高发趋势。

The relationship between respiratory system disease and the sandstorm weather is analyzed by using outpatient data from a hospital in Lanzhou and sandstorm data of Hexi corridor of Gansu province and sandstorm data of Lanzhou. The results show that outpatient would have a obvious uptrend after one day or two days when sandstorm happended in Hexi corridor and in Lanzhou with no precipitation in those regions.
