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。
利用梧州市5箇代錶站1961~2008年的氣溫、降水資料,用降水距平百分率(R指標)的榦旱等級劃分方法,併引入攷慮氣溫的P指標對榦旱等級進行劃分,揭示區域內夏旱髮生的基本特徵。結果錶明:梧州夏旱頻次高,夏旱存在自身的週期性和連續髮生的規律,在地理分佈上為中南部重于北部。併據此初步探討夏季榦旱的成因及對水稻產量的影響。

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 con- sidered 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 the influence of the rice yield were discussed. drought and
