| 摘 要： | 通过对大峪河1955～2006年的径流序列进行趋势性、周期性以及混沌特性分析,初步揭示了大峪河径流变化特件及其规律,即:大峪站实测年径流序列呈递减趋势,但不显著;年径流序列变化的短周期为4～8 a,长周期为12～25 a;而且其月径流序列存在一定的混沌特性.

| Abstract: | The tendency、periodicity and chaos characters of the runoff series was analysed at the Dayu River from 1955 to 2006,the change characteristics and rules was revealed,the annual runoff series has declined tendency,but it is not obvious;the short cycle of the annual runoff changes is 4-8 a,the long cycle is 12-25 a;and the monthly runoff series has some chaos characters. |
