| 中文摘要: |
| 通过建立黄河自净需水量模型，分别对黄河花园口以上河段以及利津断面的自净需水量进行计算。计算结果表明，在现状入黄城镇点源超标排放、入黄支流污染严重的情况下，实现黄河水质目标所需的稀释水量较大，黄河现状水资源无法满足要求。在入黄城镇点源达标排放、入黄支流实现入黄水功能区水质目标的前提下，黄河自净需水量随季节在年内变化不大，枯水低温期所需自净需水量稍高，其中90％保证率最枯月平均流量能够基本满足黄河自净需水量，但青铜峡、石嘴山、潼关等污染严重河段所需自净需水量仍然较大，对应最枯月平均流量保证率介于8.5%～87%之间。 |
| 英文摘要: |
| This study established a model of self-purification water requirements for the Yellow River and was applied to the upstream reaches of Huayuankou and the river section at Lijin. The results show that in current situation which the point-source pollution of towns discharged excessive pollutants into the Yellow River and the tributaries were seriously polluted，the self-purification water requirements are very large and current water resources of the Yellow River cannot meet the need. In contrast，if the point source pollution of towns up-to-standard discharged and the water quality in tributaries satisfied the water quality objectives of different water function zones，there is not too much change about self-purification water requirements in the Yellow River in different seasons，and self-purification water requirements in dry season and low temperature period is slightly bigger than in other periods. The average flow of the most dry month in 90% probability can basically meet the self-purification water requirements of the Yellow River except for the seriously polluted reaches，such as the Qingtongxia， Shizuishan， and Tongguan， with the corresponding guarantee rate of average flow in the most dry month between 8.5% and 87%. |
