摘要: 目的 研究水稻种植区内蚊虫分布和地理景观因素之间的关系。方法 在研究中依据景观因素不同建立蚊虫调查点,采用人帐法调查,使用遥感分析技术对不同景观组成进行提取,统计分析地理景观与蚊虫分布之间的关系。结果 13个调查点中捕获的库蚊属最多,占捕蚊总数的93.67%,捕获数量最多的是淡色库蚊为3950只;研究结果表明蚊虫的孳生和繁殖与地理景观有着密切的相关关系。凶小库蚊数量与居民区面积的百分比之间,中华按蚊数量与稻田面积百分比之间,三带喙库蚊数量与稻田及林地面积百分比之间,淡色库蚊数量与污水沟、林地、旱田面积百分比之间均有非常显著的正相关。结论 应用航空遥感技术能较好地监测稻田种植区内各种地理景观因素的变化,可应用于蚊媒传染病的控制研究。

Abstract: Objective Study the relationship of geographical landscapes and mosquito distribution in rice growing districts.Methods The survey sites were established according to variance of geographical landscapes.The species and densities of adult mosquito were investigated with mosquito net,and the constitution of different geographical landscapes was extracted with romote sensing(RS) and geography information system(GIS),and then the relationship between geographical landscapes and mosquito distribution was analysised by SAS software.Results There were four species of Culex in 13 survey sites,accounting for 82.53% of all the captured mosquito species.The quantity of Culex pipiens pallens was the most among the captured mosquitoes,about 3950 mosquito.The results showed that the distribution of mosquitoes had the close relationship with geographical landscapes.There were significant positive correlations between the amount of Cx.modestus and the percent of residential area,the quantity of Anopheles sinensis and the percent of rice field area,the number of Cx.tritaeniorhynchus and the percent of rice field and forest areas,the amount of Cx.pipiens pallens and the percent of sewage,woodland and glebe areas.Conclusion The combination of RS and GIS can effectively monitor the variance of geographical landscapes factors in the paddy growing districts,which can be used to the control of mosquito-borne diseases.
