长江中下游地区高温时空分布及水稻花期的避害对策

Spatial and Temporal Distribution of High Temperature and Strategies to Rice Florescence Harm in the Lower-middle Reaches of Yangtze River

以湖南、湖北、江西、安徽、江苏和浙江6省各代表台站1965-2004年近40a的6-8月日平均气温与最高温度为原始数据,分析了长江中下游地区各省高温的发生概率、高温发生年平均天数以及高温起止日期,总结出长江中下游地区6省的高温时空分布规律,并提出了水稻生长避开高温危害的措施,为长江流域水稻稳产高产提供重要的参考。

Occurrence probability, annual mean day, beginning and ending time of high temperature were analyzed respectively based on daily average temperature and the highest temperature in June and August of 1965 to 2004 from agro-meteorological stations in Hunan, Hubei, Jiangxi, Anhui, Jiangsu and Zhejiang provinces. Spatial and temporal distribution of high temperature in six provinces was summarized according to above analysis. The measures to avoid to high temperature and corresponding strategies were put forward, which could provide the important reference to rice production in Yangtze River Basin.
