摘　　要：烟草病毒病(tobacco mosaic virus、cucumber mosaic virus、potato virus Y等)作为世界上一种普遍发生的烟草病害,常在烟草生产上引起巨大的损失。为了解烟草烟草病毒病在大田的空间分布情况,本研究通过田间系统调查,分析烟草病毒病的生态位特征。调查结果表明,龙岩地区烟草病毒病的寄主生态位宽度较大,随着烟草的生长,烟草病毒病的生态位宽度逐渐增大,后期数值接近0.9,表明烟草病毒病可以侵染该地区大多数烟草。同时黄瓜花叶病毒病发病率的生态位宽度为0.94,普通花叶病毒病发病率的生态位宽度为0.8256,表明黄瓜花叶病的扩展速度比普通花叶病更快。对侵染性病害的生态位进行研究可为病害进行有效的生态调控提供基础。Tobacco virus disease(tobacco mosaic virus,cucumber mosaic virus,potato virus Y,etc.) is one of the most common tobacco diseases in the world,which often causes great loss in tobacco production.In order to understand the spatial distribution of tobacco virus disease in field,this paper analyzed the ecological niche characteristics of virus disease pathogens through field systematic investigation.The results show that the host ecological niche breadth of tobacco virus disease is large in Longyan tobacco planting area.With the growth of tobacco,the ecological niche breadth of tobacco virus disease gradually increases,and the value in the later growth stage is close to 0.9,indicating that the virus disease could infect most of the tobacco in the area.At the same time,the ecological niche breadth of the incidence of cucumber mosaic virus disease is 0.94,and that of common mosaic virus disease is 0.8256,indicating that the spread rate of cucumber mosaic disease is faster than that of common mosaic disease.The research on the ecological niche of infectious diseases could provide a basis for the effective ecological regulation of diseases.
