气象因素与霍乱发病关系的生态学研究

目的探讨气象因素与霍乱发病的关系.方法将绍兴地区1991～2001年霍乱各年6～11月份月平均发病率数据进行正态化处理后,再利用方差分析、回归分析对可能影响霍乱发病的气温、气压、相对湿度、日照时数、降水量等5项研究变量进行单因素相关分析和多元逐步回归分析.结果霍乱的发病与气温呈显著性正相关,与气压呈显著性负相关.结论霍乱发病与高气温、低气压有关.

An Ecological Study on the Association between Meteorological Factors and Incidence of Cholera

Objective Analys of association between meteorological factors and incidence of cholera. Methods The incidental rate of cholera in Shaoxing were treated by normality from 1991 to 2001.Analysis of association between incidence of cholera and meteorological factors,including temperature,atmospheric pressure,relative humidity,sunshine time,rainfall etc,was done by simple correlation and multiple stepwise regression. Results There was a significant positive correlation between incidence of cholera and temperature,a significantly negative correlation with atmospheric pressure. Conclusions The incidence of cholera is found to be correlated to the high temperature,low atmospheric pressure.
