摘　　要：利用CLIMEX生态气候模型和GIS系统,对栎树猝死病原在我国的适生区进行预测。模型分析表明:温度和湿度是栎树猝死病分布的主要气候限制因子,新疆、甘肃、内蒙古、宁夏和青海地区主要受干胁迫影响,广西、广东、江西和海南的大部分地区主要受热胁迫影响,这些地区均不适宜栎树猝死病菌生存。栎树猝死病菌适合于阴冷潮湿环境下生长,长江流域附近被划为边缘适宜区域,主要包括山东、河南、陕西、江苏和湖南的部分地区,其中还包括黑龙江、吉林和辽宁的东部地区和台湾省南部地区。适宜区域和最适宜区域主要集中在中国西南地区的四川、贵州、云南、重庆和中部的湖北,以及东南部的浙江、江苏、安徽、福建和台湾。这些区域正是我国杜鹃花属、栎属和石栎属等重要寄主的主要分布地区,提前预防该病害入侵是非常必要的。CLIMEX model and GIS were used to predict the Oak Sudden Death in its distribution regions of China. The model indicated that temperature and moisture were major climatic limiting factors which prevented the disease from burst. Both dry climate in regions of Xinjiang, Gansu, Inner Mongolia, Ningxia and Qinghai, and high temperature in the most regions of Guangxi, Guangdong,Jiangxi,Hunan,and Hainan may limited development of the disease. The disease is fond of the cool and moisture environment. Therefore, the regions along the Yangtze River Basin were designated as its marginal area of occurrence, including the part of Shandong,Henan,Shaanxi,Jiangsu, Hunan and on the surrounding. The suitable and the most suitable areas for the disease mainly located in Southwest China（ Sichuan, Guizhou, Yunnan, Chongqing）, the central China（Hubei） and the Southeast China（ Zhejiang, Jiangsu, Anhui, Fujian and Taiwan）. These regions had the largest distribution of host plants, such as Rhododendron spp., Quercus spp., Lithocarpus spp. and so on. It is imperative to prevent the disease from invasion to the regions.
