摘要
根据湖北省70个气象台站1971～2004年共34 a的历史气象资料,统计计算了各地每一天引起水稻高温热害的持续高温天气的发生机率,分析了发生机率的时空变化规律,确定了各地高温热害不同等级风险期的起始、终止日期及持续天数,并据此把湖北省水稻种植区划分成不同等级的高温热害区域,对各区域提出了躲避高温热害的几点措施和建议。
The spatial and temporal distribution of rice heat injury of present and future in Hubei province were studied by analy- zing the climatic data of 70 weather stations in recent 34 years. In order to evaluate the risk level of heat - injury for different regions, the occurrence date, termination date and duration days were proposed, and Hubei province was divided into six regions. At the end, different measures should be taken to prevent and decrease heat injury of rice.
