| 摘 要： | 利用JICA项目（中日合作灾害研究中心项目）新津（103°49′16″E、30°27′″31″N，海拔429．75m）、达县（107°30′24″E、31°12′27″N，海拔313．63m）、北碚（106°26′36″E、29°50′33″N，海拔217．43m）3站2008～2009年的地基GPS资料，分析了四川盆地可降水量特征。结果表明，四川盆地全年可降水量为11304．7mm，十分丰富；一年之中，可降水量夏季最大，秋季次之，春季略低于秋季，冬季最小；可降水量月变化明显，昼夜月变化趋势则基本相同；同时，四川盆地全年可降水量空间分布较均匀。 |

| Abstract: | According to the ground-based GPS data of Xinjin(103°49′16″E,30°27′31″N,429.75 m),Daxian(107°30′24″E,31°12′27″N,313.63 m) and Beibei(106°26′36″E,29°50′33″N,217.43 m) in JICA(Japan International Cooperation Agency) program during 2008-2009,the characteristics of precipitable water in Sichuan Basin are analyzed.The results show that the annual precipitable water in Sichuan Basin is very abundant with 11304.7mm,the precipitation is the most in summer,followed by in autumn,then in spring,and the least in winter;Moreover,the precipitable water varies obviously from month to month,while the monthly variation trend of the nighttime is almost the same as that of the day time;the spatial distribution of precipitable water in Sichuan Basin during the whole year is relatively uniform as well. |
