摘要
对黑河出山口莺落峡站来径流的变化趋势进行了分析,结果表明:黑河流域径流整体上呈丰枯交替的周期性变化,出现了多个丰水段和枯水段,丰水年和枯水年出现的几率大致相等;未来黑河流域径流仍将周期性丰枯交替变化,莺落峡站多年平均径流量仍将在15.8亿m3附近波动。
The analysis of change trend of runoff of Yingluoxia Station in Heihe River over the past 50 years shows that： the runoff in Heihe River basin as a whole is subject to high flow and low flow alternating periodic change,multiple high flow periods and low flow periods have appeared,the emergent probability for high flow year and low flow year is roughly equal;in future,Heihe River basin runoff will continue to periodically alternate with high flow and low flow and annual mean runoff of Yingluoxia Station will continue to fluctuate around 1.58 billion m3.
