摘　　要：作者于1990～1995年调查我国大、小麦各生态区,共计20个省、市、区,116个县、市的大麦黄花叶病、小麦黄花叶病(小麦梭条斑花叶病)和小麦土传花叶病的分布区域。结果表明,3种真菌传病毒病其分布仅限于冬麦区。大麦黄花叶病主要集中分布在长江三角洲、钱塘江流域和东部沿海。小麦黄花叶病主要分布于长江中、下游及其支流大渡河、青衣江,黄河中、下游及其支流渭河流域、淮河流域。小麦土传花叶病仅局部冬麦区发生,与小麦黄花叶病混合并发。3种病害的分布范围为北纬28～37°50′东经102～122°40′之间。The distribution regions of BaYMV, WYMV(WSSMV) ,and WSBMV in all barley and wheat ecological districts,including 20 provinces,cities and regions,and 116 counties/cities, were investigated in China from 1990 to 1995. The results show that these three diseases were mainly distributed in winter wheat/barley regions around Yangtze River,Yellow River,Huaihe River and Qiantang River. BaYMV was mainly distributed around the Yangtze Triangle Delta,Qiantang River and Eastern Coast Regions. WYMV was mainly distributed around the middle-lower reaches of the Yangtze and its tributaries including Qingyi River and Dadu River,and around the middle-lower reaches of the Yellow River and its tributaries including Weihe River and Huaihe River. The co-infection of WSBMV and WYMV occurred only in some winter barley/wheat regions in the northern areas,the Yellow River and Huanhe River regions,and the middle-lower reaches of the Yangtze. The distribution range of these three diseases was located at 28 - 37°50'N and 102 -122°40'E. This paper also discussed the ecological factors and the reasons of influencing distribution.
