Study about the Conditions of Ensuring Yellow River Delta Water Resources
About 90％ water resources demanded by the Yellow River delta comes from the Yellow River. Defended by the embankments along the river, no sewage can flow into it from discharge outlets and tributaries, as a result, the water quality of the Yellow River delta is mainly decided by both the quality and quantity of the water released from the Xiaolangdi Reservoir and the sewage discharged in the lower reaches. Taking the water quality of Lijin section as a typical one for the Yellow River delta, 6 cross sections in the reach from Xiaolangdi to Lijin were selected for water quality evaluation, its change analysis and demonstration of water quality guaranteed condition of Lijin section. This research has revealed that assurance rate of water quality of Lijin section was 80％ when the discharge of the Xiaolangdi is upto or over 230m3/s. If the quality of water discharged from the Xiaolangdi did not go beyond Class IV, the assurance rate of water quality of Lijin section was above 80％, the assurance rate of water quality of Lijin was 87％ when the discharge of Lijin Section came to 88m3/s and above.
