湖北省近50年来的气温和降水变化趋势分析

温度和降水对气候的变化有着极为显著的影响，因此，研究温度和降水的变化规律对于促进农业生产、水资源的合理规划和调度具有十分重要的意义。利用湖北地区1957～2006年的气象资料，选取16个有代表性的站点，具体分析了近50年该地区气温与降水之间的关系。结果表明，夏季总降水量与温度有较好的相关性，而全年及春、秋、冬各季气温与降水的相关性规律表现不明显。这为指导当地农业生产以及充分合理利用当地的气候资源提供一定的参考。

On the Changing Trend of Temperature and Precipitation in Hubei Province in Recent 50 Years

Temperature and precipitation changes have a very significant impact on climate so that the study of temperature and precipitation changes is significant for promoting the agricultural production,water resources planning and scheduling.This study aimed to analyze the correlation between temperature and precipitation in recent 50 years by using the meteorological data of Hubei Province during 1957-2006 in 16 representative sites.The results showed that a quite obvious relevance was demonstrated between the total precipitation and temperature in summer,but in spring or the whole year,autumn and winter,the relevance of the law of the performance was not obvious,which provided a guidance to the local agricultural production as well as full and rational utilization of the local climatic resources.
