目的探讨首都机场周边蚊虫密度与气象因素之间的关系,筛选适合因子预测蚊虫密度变化趋势。方法监测2011-2013年5-10月首都机场周边蚊虫密度并收集同期气象资料,气象数据经膨化处理,用SPSS 20.0软件分析两者相关性,并用逐步回归分析建立蚊虫密度的气象因子拟合模型。结果蚊虫季节消长曲线为单峰型,5月出现,6-9月达高峰,10月消亡。蚊虫密度与前一月平均温度、前一月平均气压等相关,与月日照、相对湿度和温差无关。结论气象因素对蚊虫密度有重要影响,可以利用气压、降雨量拟合模型预测蚊虫密度变化趋势。
Objective To explore the relationship between mosquito density and meteorological factors in the vicinity of Capital Airport and to screen suitable factors to predict the trend of mosquito density. Methods The mosquito density around the capital airport from May to October in 2011-2013 was monitored and the meteorological data collected during the same period. The meteorological data were processed by puffing. SPSS 20.0 software was used to analyze the correlation between the mosquitoes and the meteorological factors fitted by stepwise regression analysis . Results The seasonal fluctuation curves of mosquitoes were unimodal, appeared in May, reached the peak in June-September, and died in October. The density of mosquitoes is related to the average temperature in the previous month, the average pressure in the previous month and so on, regardless of the sunshine, relative humidity and temperature difference. Conclusion The meteorological factors have an important influence on the density of mosquitoes. Using the fitting models of pressure and rainfall, the trend of mosquito density can be predicted.
