摘要： 黑河下游河道都是天然河道,断面不规则,属宽浅型沙质河床,河道渗漏量大。下游的天然生态正是由于河道的渗漏水量补给地下水来支撑天然植被的生长,所以河道的渗漏对于下游生态意义重大。而对于黑河下游河道渗漏情况,长期以来没有系统地进行监测,利用常规的渗透系数法无法计算,目前大多是估计或者简化处理。论文根据水量实时调度和长系列水资源配置的需要,根据断面流量相关关系对其渗漏规律进行分析,分别得到了短期实时调度考虑河道前期水情状况影响下的河道渗漏规律以及长系列水资源配置情况下平均的渗漏规律。

Abstract: The river courses in the lower Heihe River are all natural ones with irregular cross sections and great seepage,belonging to broad-shallow type of sandy riverbed.The channel seepage is of great significance to ecosystems in the lower reaches which supply groundwater to sustain natural vegetation.However the seepage situation of river courses in the lower Heihe River has not been monitored and investigated for a long time.The usual percolation coefficient method thus cannot be used for calculation.At present, the amount of seepage is mostly estimated with relatively simple ways.Based on the relationship between sections and discharge,the seepage laws are analyzed according to the need of water resources real-time regulation and long series allocation.Meanwhile channel seepage laws considering the short term effects of water regime and average seepage laws of long series water resources allocation are achieved.

Key words: water resource, channel leakage, correlativity, lower Heihe River
