| 摘 要： | 用线性拟合方法，对１９５０ 年至１９９６ 年浙江省１０ 个气象代表站的月降水量和年降水量资料进行了分析，结果表明：（１）全省年降水量的变化趋势并不明显；（２）３ 月的降水量，全省大部分地区呈较明显的增多趋势；（３）５ 月的降水量，全省大部分地区呈较明显的减少趋势；（４）７ 月的降水量全省部分地区呈较明显的增多趋势⒚总之，浙江省的降水在一年内呈现出一种时间上相对集中的变化趋势⒚

| Abstract: | Using linear fitting methods,the rainfall data,both annual and monthly,from 1950 to 1996 for ten major weather stations in Zhejiang are investigated.The results indicate:1) there is no obvious change in annual rainfall in Zhejiang except for southeast areas where annual rainfall tends to decrease;2) an apparent increasing trend is detected in monthly rainfall in both March and July;3) a decrease tendency in monthly rainfall is found in May. |
