| 摘 要： | 根据1956-2000年各月降水资料,在江苏沿海地区选取7个代表站,对降水距平百分率、降水标准化变量和Z指数进行了对比分析;并对依据Z指数划分旱涝等级的界限值进行了调整,得到修正后的Z指数更适合本地区单站旱涝指标的划分.

| Abstract: | With the monthly precipitation data of 7 sampling meteorological stations in the coastal area of Jiangsu Province from 1956 to 2000,the anomalous percentage of precipitation,the standardized variable of precipitation and the Z-index are compared.The grades of drought/flood characterized by Z-index are reevaluated,and the modified Z-index is more suitable for the coastal area of Jiangsu Province. |
