| 摘 要： | 使用我国４００余站１９５１－１９９０年年降水量序列，利用比值法检验其非均一性问题。结果表明，该方法对判断我国年降水量是否均一较为有效的，我国台站迁移及雨量器的改变是引起年降水量序列非均一的主要原因。

| Abstract: | The inhomogeneity has been tested by using ratio method,based on annual precipitation series from 1951 to 1990 for four hundred stations in China. The results suggest that this method is effective to judge the inhomogeneity of annual precipitation series changes of stations and guages are major reasons which caused the inhomogeneity of annual precipitation series. |
