黄河下游属于过度开发的河流.长期以来。重视经济社会效益,而较为轻视环境和生态效益;上世纪80～90年代,下游出现连年断流及“二级悬河”两个突出问题。过量引黄,引黄总水量大大超过母亲河的承受能力,生产用水与社会用水大量挤占冲沙用水及生态用水,是上述问题形成的直接原因。为了维持黄河健康生命,保持河流永续利用,根本对策是在全流域建设高效、节水、防污型社会。节制社会经济用水;变粗放灌溉为科学灌溉;工业广用循环水;城市绿化及冲洗采用中水。制止对水质的污染。我们认为恢复黄河生态良性维持应包括三方面的指标:(1)下游排洪主槽通过调水调沙逐步恢复到6000m~3/s的过洪能力;(2)河水污染程度应稀释和降解到至少达到国家Ⅲ类水标准;(3)保证湿地及河、海、空中生物的良性生长环境。只要全流域以科学发展观为统领,实现人与河流和谐发展,经过10～20年的努力,上述目标是可以达到的。
The lower Yellow River belongs to the over-developed river. Pay more attention to the economic and social benefits, and pay more attention to the environmental and ecological benefits. In the 1980s and 1990s, two outstanding problems occurred in the downstream such as continuous flow discontinuities and “secondary suspended rivers”. Excessive yellowing, yellowing of the total water greatly exceeds the capacity of the mother river, a large number of production water and social water occupation of flushing water and ecological water, the formation of these problems is the direct cause. In order to maintain the healthy life of the Yellow River and maintain the sustainable use of the river, the fundamental solution is to build an efficient, water-saving and pollution-resistant society in the whole basin. Control of social and economic water; thicker irrigation for scientific irrigation; industrial use of recycled water; urban greening and flushing in the water. Stop water pollution. In our opinion, the restoration of the ecological soundness of the Yellow River should include three indicators: (1) the flood discharge capacity of the downstream main drainage channel should be gradually restored to 6,000m 3 / s through water and sediment adjustment; (2) the degree of river pollution should be diluted and degraded To at least meet the national Class III water standards; (3) to ensure the benign growth environment of wetlands and rivers, sea and air organisms. As long as the whole basin is guided by the scientific concept of development and achieves the harmonious development of man and river, after 10 to 20 years of hard work, the above goal can be achieved.
