| 摘 要： | 利用1961～2007年海南省琼山站的降水量和20cm口径小型蒸发皿资料,采用累积距平曲线和线性倾向估计方法,对海口市降水量、蒸发量的变化及其对干燥度的影响进行了分析.结果表明:海口市年、季降水量的年际变化明显,年、季蒸发量的年代际变化明显;近50a海口市年、季降水量没有显著的线性变化趋势,但年、春、秋、冬季的蒸发量均有显著的线性减少趋势;受此影响,近50a海口市气候总体趋于更加湿润,但2003～2007年由于降水量减少,蒸发量增大,气候处于相对干燥时期.

| Abstract: | Basing the data of precipitation from Qiongshan station and evaporation data of evaporating dish(20cm caliber) from 1961 to 2007,using the methods of cumulative factors and linear tendency estimation,the variation of precipitation,evaporation of Haikou city and its influence on drought were analyzed.The results show that rainfall and evaporation of quarter and annual in Haikou city exhibits significant interannual variation.And the rainfall of quarter and annual have no significant linear trends in the last... |
