| 摘 要： | 根据1961~2007年川渝地区156个台站逐日温度降水资料,测试了3种单站旱涝指标,并做了相互比较。结果表明,CI指数能较好地反映逐日的干旱变化,Z指数对月、季的旱涝评估较好,对Z指数的划分标准进行修正,修正后Z指数更适合三峡库区上游(川渝地区)旱涝等级的划分。基于各站Z指数,提出了一种能反映三峡库区上游区域旱涝强度的区域旱涝计算方法。 |

| Abstract: | By using of the daily temperature and precipitation data of 156 sampling meteorological stat ions in Sichuan-Chongqing area from 1961 to 2007,the three single indexes for flood and drought were tested and compared with each other.The results indicated that Ci-index could better reflect the day-to-day flood and drought changes,Z-index was better to reflect month and season flood and drought changes,grades of flood and drought for Z-index were again determined,the modified Z-index was cognized to be optimum f... |
