Based on the unique characteristics of the Yellow River and previous research on its ecological water requirement, the present paper recommends that the water requirement for transport in the flood season and base ecological flow in non-flood season should be both included in the ecological water requirement. The water requirement for transport is 80 × 108-120 × 108 m3 per year if the bankfull discharge carries the largest sediment and contaminant load over a long period of time. The base ecological flows in non-flood season at Huayuankou and Lijin stations are 80 × 108-100×108 m3 and 50 × 108-60 × 108 m3, respectively.

通过分析黄河下游1958～2000年实测生态可用水，探讨生态需水量内涵，根据黄河特殊性及黄河生态需水量的研究现状，将维持和保护河流功能的黄河下游生态需水量分为汛期输运水量和非汛期生态基流量，在平滩流量输运能力最强的前提下，估算黄河下游汛期输运水量为80～120亿m3，根据实测资料估算作为黄河下游水量控制断面花园口水文站和作为河口地区水量控制断面利津水文站的非汛期生态基分别为80～100亿m3和50～60亿m3。

These Thoughts so oppress'd my Mind, that I began to give over my Enterprize, and having haled my Boat into a little Creek on the Shore, I stept out, and sat me down upon a little rising bit of Ground, very pensive and anxious, between Fear and Desire about my Voyage; when as I was musing, I could perceive that the Tide was turn'd, and the Flood come on, upon which my going was for so many Hours impracticable; upon this presently it occurr'd to me, that I should go up to the highest Piece of Ground I could find, and observe, if I could, how the Sets of the Tide, or Currents lay, when the Flood came in, that I might judge whether if I was driven one way out, I might not expect to be driven another way home, with the same Rapidness of the Currents: This Thought was no sooner in my Head, but I cast my Eye upon a little Hill, which sufficiently over-look'd the Sea both ways, and from whence I had a clear view of the Currents, or Sets of the Tide, and which way I was to guide my self in my Return; here I found, that as the Current of the Ebb set out close by the South Point of the Island; so the Current of the Flood set in close by the Shore of the North Side, and that I had nothing to do but to keep to the North of the Island in my Return, and I should do well enough.

我思想压力很大，不得不考虑放弃原定的计划。我把小船拉进沿岸的一条小河里，自己迈步上岸，在一块小小的高地上坐下来沉思。我心情忧郁，心绪不宁。我害怕死，又想前去探个究竟。正当我沉思默想之际，只见潮流起了变化，潮水开始上涨。这样，我一时肯定走不成了。这时，我忽然想到，应该找一个最高的地方，上去观察一下潮水上涨时那两股急流的流向，从中我可以作出判断，万一我被一股急流冲入大海，是否有可能被另一股急流冲回来。我刚想到这一层，就看见附近有一座小山；从山上可以看到左右两边的海面，并对两股急流的流向可以一目了然，从而可以确定我回来时应走哪一个方向。到了山上，我发现那退潮的急流是沿着小岛的南部往外流的，而那涨潮的急流是沿着小岛的北部往里流的。这样，我回来时，小舟只要沿着北部行驶，自然就可以被涨潮的急流带回来。
