| 摘 要： | 根据黑河流域重点控制水文站莺落峡、正义峡实测月径流量观测资料,应用不均匀系数、集中度(期)、变化幅度等方法指标,分析了黑河流域径流年内变化规律;采用累积滤波器和Mann-Kendall秩相关法诊断了各月径流量的变化趋势.结果表明:①对于莺落峡站,总体上各个年代径流年内分配均呈明显的"单峰型"分布,其径流量7月达到极大值... |

| Abstract: | Based on the observed monthly streamflow of 2 key hydrological control stations in Heihe River Basin since 1950, by using nonuniformity coefficient and concentration degree (period) ,we studied the intra-annual change. The Mann-Kendall test and the cumulative filter methods were employed to detect the trends of intra-annual runoff. The results indicate that: 1) Generally, the annual runoff distribution reached a maximum in July at Yingluoxia, and the curve of it had a single peak value. At Zhengyixia the an... |
