从防洪和水资源利用的角度，对黄河中游干流河口镇、龙门、潼关３个站的洪水特性进行了深入分析，初步研究了洪水的变化特点。龙门大洪水大多发生在７、８月份的伏汛期，洪水主要来源于河口镇－吴堡区间的支流，近年来发生大洪水的几率并未减小，仍是防洪的重点时期。同时受河口镇以上及渭河来水影响，秋汛期洪峰流量明显降低，大洪水出现几率减小，可以考虑这一时期水资源的利用问题。
From the perspectives of flood control and water resources utilization, the flood characteristics of three stations in Hekouzhen, Longmen and Tongguan in the middle reaches of the Yellow River are analyzed in depth, and the characteristics of the flood are preliminarily studied. The floods of the gantry mostly occurred in July and August during the flood season. The flood mainly came from the tributaries of the estuary to the wubu district. The probability of major floods in recent years did not decrease, which was still the key flood control period. At the same time by the river mouth above the town and the Weihe River, the autumn flood peak discharge decreased significantly, the probability of a big flood to reduce, you can consider the use of water resources during this period.
