| 摘 要： | 根据西北地区８３个台站１９６１－１９９０年月降水量资料，对降水距平百分离，降水标准化变量和Ｚ指数进行了对比分析，并怼Ｚ指数的旱涝等级标准进行了重新确定，认为经修正后的Ｚ指数更适合于西北地区单 站各旱涝时段的划分。

| Abstract: | By use of the monthly precipitation data of 83 sampling meteorological stations in the Northwest China from 1961 to 1990,the anomalous percentage of precipitation, the standard variable of precipitation and the Z-index were tested and compared with each other. Grades of flood/drought for Z-index were again determined, the modified Z-index was recognized to be optimum for differentiating station flood or drought in the Northwest China. On this basis, flood and drought differentiating indices were given for the Northwest China. |
