摘要
1997年，由于黄河流域降雨、径流量较常年明显偏少，水资源供需矛盾十分突出，黄河下游出现了有资料记录以来断流最为严重的一年，利津站于2月7日开始断流，截止到12月31日，断流13次，共计226d，与有记录以来的历史资料比较，呈现出断流开始时间最早、恢复过流时间最晚、断流河段最长、断流次数最多、断流时间最长等特点。另外，黄河中游各主要支流控制站亦多数出现断流或接近断流，其中华县站出现有资料记录以来的首次断流。黄河干流头道拐和潼关站出现了有资料记录以来的最小流量。
There was conspicuous contradiction appeal between water supply and demand in the Yellow River basin in 1997 because of much less precipitation and runoff than nounal and no-flow in the lower reaches in 1997 was the most serious in the records. There were 11 times of no-flow at Lijin station with total 122 days from Feb.7 to Dec. 31, which have characteristics of the earliest beginning, the latest recovery of flow, the most times, the longest reaches and the longest duration. No-flow or nearly no-flow happened at coned stations of major tributries in which it is the first time of no-flow at Huedan station. The minimum flow happened at Toudaoguai and Tongguan stations in the main stem in the aecord.
