目的探讨深圳市大工业区蚊虫密度与气象因素的关系,为有效监控蚊虫密度及蚊媒传染病提供科学依据。方法对深圳市大工业区2011—2013年监测的蚊虫密度资料与同期的降水量、平均气温、最高气温等气象数据资料进行相关性及多元逐步回归分析,P<0.05为差异有统计学意义。结果 2011—2013年蚊虫密度与同期的降水量、最高气温、平均气温、最低气温、平均相对湿度、最小相对湿度、雨日、雷暴日等呈显著正相关(r=0.456、0.537、0.555、0.517、0.535、0.485、0.510、0.491,均P<0.05);而与霾和大雾日呈负相关(r=-0.420、-0.378,均P<0.05)。平均温度和平均相对湿度进入回归模型(t=2.510、2.333,均P<0.05)。结论影响深圳市大工业区蚊虫密度的主要气象因素为平均气温和平均相对湿度,其中平均气温对蚊虫密度的影响最大,平均相对湿度次之。
Objective To explore the relationship between mosquito density and meteorological factors in a large industrial zone in Shenzhen and provide a scientific basis for effectively monitoring mosquito density and mosquito-borne infectious diseases. Methods Correlation and multiple stepwise regression analysis were conducted between the mosquito density data monitored in the large industrial area of Shenzhen City in 2011-2013 with the precipitation data, mean temperature and maximum air temperature in the same period. P <0.05 was considered as statistically significant. Results The mosquito density in 2011-2013 was significantly positively correlated with the precipitation, the highest temperature, the average temperature, the lowest temperature, the average relative humidity, the minimum relative humidity, the rainy days and the thunderstorm days in the same period (r = 0.456, 0.537, 0.555 and 0.517 , 0.535,0.485,0.510,0.491, all P <0.05), but negatively correlated with haze and fog day (r = -0.420, -0.378, all P <0.05). Average temperature and average relative humidity entered the regression model (t = 2.510,2.333, both P <0.05). Conclusion The main meteorological factors influencing the mosquito density in large industrial area of Shenzhen are the average temperature and the average relative humidity, of which the average temperature has the greatest influence on the mosquito density and the average relative humidity is the second.
