摘　　要：自2009年南方水稻黑条矮缩病在中国南方稻区局部首次暴发为害以来,在农业部的高度重视和支持下,全国农业技术推广服务中心组织全国植保体系系统开展病害的流行规律、调查监测和预测预报技术研究,初步掌握了病害的发生流行动态和特点,明确了影响我国南方稻区病害发生的毒源地主要为中南半岛的越南中北部及红河平原,其次为我国的海南和云南南部山区。2010年以来,制定了病害测报技术规范,建立了监测预警网络体系,积极开展预测预报工作。南方水稻黑条矮缩病的监测预报经历了由"恐慌"到"淡定"、由"心中无数"到"心中有数"、由"无所适从"到"有条不紊"的过程,病害预测的准确性明显提高,在有效指导防治、控制病害流行、减轻危害损失方面发挥了重要作用。Since the first outbreak of southern rice black-streaked dwarf virus（SRBSDV） disease in rice planting area in southern China in 2009,epidemic patterns of this disease,systematic monitoring and forecasting technologies were studied under organization of National Agro-tech Extension and Service Center and with support of Ministry of Agriculture of China.It was concluded that source regions of the disease,affecting occurrence of southern China,were mainly from northern and central Vietnam and Red River plain in Central-Southern Peninsular,and secondly from Hainan and southern Yunnan in China.From 2010,technical rules and system for investigation and forecast of the disease were gradually established,which changed the forecasting of the disease from ＂panic＂ to ＂calm＂,from ＂little known＂ to ＂well-known＂,from ＂nothing to take＂ to ＂everything in arrange＂.Forecasting of this disease had been remarkably promoted and played more and more important roles in guiding disease control,slowing down epidemics,and reducing damage.
