| 摘 要： | 利用四川和重庆共69个气象站1960-2008年的气象资料,分析了四川盆地东部近50年水稻高温热害的时空分布规律.结果表明:①水稻高温热害以20世纪60年代和70年代最重,20世纪80年代最轻,21世纪有加重的趋势;轻度高温热害呈波动下降的趋势,而重度高温热害呈增加的趋势.②水稻高温热害高值区位于四川盆地东部,中部呈西南向东北方向延伸,重度高温热害的高发区域主要集中在重庆的东北部.③根据气候趋势,采取调整播期和栽期,选择抗高温的品种,用日灌夜排、喷灌水雾和喷洒化学药剂等改善田间小气候条件的方式,可减轻高温热害的影响.

| Abstract: | Based on the meteorological data recorded at 69 meteorological stations in Sichuan and Chongqing from 1960 to 2008,the temporal and spatial distribution of high temperature-induced heat damage to rice crops in the eastern part of Sichuan basin in the recent 50 years was analyzed.Heat damage of rice was the heaviest in the 1960's and 1970's and the mildest in the 1980's,and showed an increasing trend in the 21st century.The mild heat damage showed a fluctuating downward trend,while the severe heat damage sho... |
