利用1964-2012年艾比湖流域博尔塔拉河径流、降水数据,运用非参数检验、集中度、小波分析等方法研究了博尔塔拉河年径流量与降水量的集中性及多时间尺度相关关系。研究表明:博尔塔拉河年径流量及降水量均通过Mann-Kendall趋势检验,全年增加显著。通过Mann-Whitney突变检验,径流量与降水量分别在1996年和1985年发生了显著的增多突变。博尔塔拉河径流量集中度呈不显著的增加趋势,降水量集中度呈不显著的减少趋势。博尔塔拉河径流量的集中度存在6、11和14a的周期变化,而降水量集中度存在12和18a周期显著。博尔塔拉河年径流量与降水量存在多时间尺度的显著相关关系,并以正相关为主。
Based on the Bortala River runoff and precipitation data in the Aibi Lake basin from 1964 to 2012, non-parametric test, concentration and wavelet analysis were used to study the annual and annual runoff and precipitation concentrations in the Bortala River. Scale-related relationship. The results show that the annual runoff and precipitation of the Bortala River have all passed the Mann-Kendall trend test and increased significantly throughout the year. By Mann-Whitney mutation test, there was a significant increase in runoff and precipitation in 1996 and 1985, respectively. Bortala River flow concentration showed no significant increase trend, precipitation concentration showed an insignificant decrease. There is a 6, 11 and 14a periodic variation in the concentration of Bortala river runoff, while there is a significant 12 and 18 a cycle of precipitation concentration. There is a significant correlation between annual runoff and precipitation in the Bortala River on a multi-time scale with a positive correlation.
