摘　　要：本项研究得出:暖雨曰≥2天的年出现频率≥6.25%、≥62.5%,暖雨日≥6天的年出现频率≥150%、≥25%,暖雨日≥2天的年出现频率≥31.25%等敏感指标;並以此分析了我国小麦赤霉病的发生界线、常发界线、极重病界线、重病界线、次偶发界线;将我国小麦赤霉病的地域分布划分为赤霉病发生气候带(Ⅰ)和赤霉病不发生气候带(Ⅱ)。Ⅰ带又分为四个气候亚带,即冬小麦赤霉病常发气候亚带(IA);冬小麦赤霉病偶发气侯亚带(IB);春小麦赤霉病常发气候亚带(IC);春小麦赤霉病偶发气候亚带(ID)。並将四个气候亚带划分为10个气候区,即冬小麦赤霉病极重病气候区(IA_1)、重病气候区(IA_2)、中等病气候区(IA_3)、偶发气候区(IB_1)、次偶发气候区(IB_2);春小麦赤霉病极重病气候区(IC_1)、重病气候区(IC_2)、中等病气候区(IC_3);偶发气候区(ID_1)、次偶发气候区(ID_2),该研究结果客观的揭示了赤霉病的地域分布规律,可为做好区域性长期预报奠定科学基础。Based on the following acquired sensitive indexes: limits of Wheat scab occurrence, frequent occurrence, the extremely serious occurrence, serious occurrence and suhoccasional occurrence, etc., the areas of Wheat scab occurrence in China are divided into two climatological zonations, that is, climatological zonation of occurrence I and climatological zonation of nonoccurrence Ⅱ. The former is divided into four climatological subzonatiuns. They are, the climatological subzonation of winter wheat scab frequent occurrence (IA), subzonation of winter wheat scab occasional occurrence (IB), subzonation of spring wheat scab frequent occurrence (IC), and subzonution of spring wheat scab occasional occurrence (ID). The four climatological subzonations are divided into ten climatological areas further. They are climatological areas of winter wheat scab extremely serious occurrence (IA_1), of area of serious occurrence (IA_2), area of middling level occurrence (IA_3), area of occasional occurrence (IB_1), and area of suboccusional occurrence (IB_2); climatological area of spring wheat scab extremely serious occurrence (IC_1), area of serious occurrence (IC_2), area of middling level occurrence (IC_3), area of occasional occurrence (ID_1), area of suboccasional occurrence (ID_2). The analysis scientifically shows the geographic distribution of wheat scab and will be scientific foundation of regional longterm prediction.
