| 摘 要： | 利用梧州市5个代表站1961～2008年的气温、降水资料，用降水距平百分率（R指标）的干旱等级划分方法，并引入考虑气温的P指标对干旱等级进行划分，揭示区域内夏旱发生的基本特征。结果表明：梧州夏旱频次高，夏旱存在自身的周期性和连续发生的规律，在地理分布上为中南部重于北部。并据此初步探讨夏季干旱的成因及对水稻产量的影响。

| Abstract: | Basing on the temperature and precipitation data from 5 represent station in Wuzhou during 1961-2008,in order to find out the basic characteristics of summer drought apearing in this area,the drought level was divided by surface precipitation percentage(R index) drought hierarchy method and P index,which considered the temperature.The results show that the frequency of summer drought is high in Wuzhou,and it has its cyclical and continuous appearing rules.Furthermore,the geographical distribution of summer drought is heavier in central south than northern.On the basis of these results,the causes of the summer drought and the influence of the rice yield were discussed. |
