摘要
目的 :研究气温、降雨量对蚊虫密度的影响。方法 :根据上海市 1990～ 1997年蚊虫消长密度与同期平均气温、降雨量 ,采用SAS 6.0 4版统计软件 ,作多元线性相关和逐步回归分析。结果 :平均气温、降雨量与同期蚊虫密度均有正相关关系 ,相关系数分别为 0 .775 0和 0 .40 89,标准偏回归系数分别为 0 .7168和 0 .2 15 8,且都有统计学意义 (P均 <0 .0 5 )。结论 :气温、降雨量均对同期蚊虫密度有影响 ,其中气温对同期蚊虫密度的影响远远大于降雨量的影响。
The author researches how atmospheric temperature and rainfall infect density of mosquito in the corresponding period. The results are as following:the relation between mean atmospheric temperature and density of mosquito was positively correlated. So was the relation between rainfall and density of mosquito. The coefficients of correlation were 0.7750 and 0.4089 . The standard partial regression coefficients were 0.7168 and 0.2158 . The results illustrate that atmospheric temperature and rainfall both influence the density of mosquito in the corresponding period. The effect that atmospheric temperature influences the density of mosquito in the corresponding period was stronger than that of rainfall.
