苹果根结线虫(Meloidogyne mali)是一种对林木、蔬菜危害很大的植物病原线虫。本研究利用MaxEnt生态位模型并结合ArcGIS软件预测苹果根结线虫在中国的适生区。预测结果表明:苹果根结线虫在中国的高度适生区主要集中在长江中下游地区。通过分析环境因子的重要性表明最冷月份最低温度、最干季度平均温度、最干季度降水量和最冷季度降水量对苹果根结线虫的分布影响最为明显。苹果根结线虫截获频率高,定殖扩散风险高,在我国有一定的适生区域,必须予以高度关注。
Abstract：Meloidogyne mali causes great damage to trees and vegetables. In this study,we used MaxEnt ecological niche model and ArcGIS software to predict the potential distribution of M. mali in China.The prediction result showed that the suitable zone would mainly concentrate in Yangtze river region of China,including Hunan,Hubei,Anhui,Jiangsu,Zhejiang and Shanghai provinces or cities. After the analysis of climatic variables,the minimum temperature of coldest month,the mean temperature of driest quarter,the precipitation of driest month and precipitation of coldest quarter were the most important climatic variables on the nematode distribution. Since the high frequency of interception,high risk of colonization and spread,certain range of potential geographic distribution in China,therefore,attention must be paid to M. mali.
