| 摘 要： | 以开都河大山口水文站1956—2006年逐月径流量数据为基本资料,采用Mann-Kendall法和小波分析法将径流划分为水文变化特征相似的6个时段,然后计算各个时段年内分配不均匀系数、集中度(期)、变化幅度和月(季)百分比等多个指标,分析开都河径流年内分配特征。结果表明,开都河来水年内变化较大,历年年内径流分配很不均匀;年内径流主要集中于6—8月份,特枯月为2—3月份;年内径流分配主要受气温变化和高山融雪的影响。 |
| 关 键 词： | 年内分配 Mann-Kendall法 不均匀系数 集中度 径流 开都河 |

| Abstract: | This paper researched on annual distribution characteristic of runoff of Kaidu River.Collecting monthly runoff from 1956 to 2006 of Dashankou hydro-station,the runoff was divided into six periods which hydrology change characteristic is similar based on Mann-Kendall rank statistical method and wavelet analysis.And then,the annual distribution characteristic of Kaidu River was further discussed by using the indexes of nonuniform coefficient,degree and time concentration,variation range,and month(season) percentage.The results showed: ① the variation of annual runoff of Kaidu River was larger,annual runoff distribution was very uneven;② the runoff mainly concentrated in June to August,the special low water month were February to March;③ the annual runoff distribution were effected on temperature change and high mountain snow melt runoff. |
| Keywords: | annual distribution Mann-Kendall rank statistical method nonuniform coefficient concentration degree annual runoff Kaidu River |
