| 摘 要： | 历代治理黄河的工程活动,都着眼于治水,而忽视了治沙,以致黄河逐渐成为地上悬河和黄淮海平原的分水岭。这既改变了我国第一大平原的原生地质环境,又在近800余年来建造了面积达10000km2以上的渤海、黄海三角洲和苏北滨海平原的新的地质环境。此文根据历史事实,建议改变传统的治黄观念,应该重视黄河泥沙这一宝贵财富,有目的、有计划地,而不是任其自然地将黄河泥沙引到适宜的地区填海造陆。黄土高原水土流失,泥沙无穷,黄河搬运日久天长,较之挖山填海,优越无比。 该文认为黄河泥沙造陆的理想地区是苏北的黄海之滨,而不是渤海。渤海面积狭小,又是我国的内海。以黄河泥沙填于渤海指日可待,而渤海变陆,对华北、东北的气候、水文、环境等都十分不利。 |

| Abstract: | Historically in China, the engineering activities of the Yellow River water conservancy were mostly focused on the water harnessing, while the silt harnessing was neglected.As a result, the Yellow River became gradually a world-famous above-ground suspended river and a "watershed" in the middle part of the Huang-Huai-Hai (Yellow R.-Huaihe R.-Haihe River)Plain.This has, on the one hand, changed the primary geological environment of the largest plain of China and, on the other hand, created the new geological environment of the Bohai Sea, Yellow River delta and coastal plain with an area over 10 000 km2 in the recent 800 odd years. Based on the historical facts, it is suggested in this paper that the traditional concept on the Yellow River water conservancy should be changed and the silt in the Yellow River should be paid attention to.The silt is regarded as a precious wealth and should be, in an aimed and planned way rather than a laissez-faire attitude, led to an appropriate area to fill the sea and create the land.As the soil loss in loess plateau is an irresistible natural process and the amount of silt is practically infinite, the sea-filling and land-creation by utilizing the transported silt by Yellow River (though in a relatively long period of time)is incomparably more advantageous than by mountain excavation and sea-filling. The paper suggests that the ideal area for the land accretion with the Yellow River silt is the Yellow Sea coast at northern Jiangsu rather than the Bohai Sea, because the latter is small in area and is our inland sea.The Bohai Sea could be quickly filled up with the silt of Yellow River, but the changing of Bohai Sea into land is quite harmful to North and Northeast China with respect to climate, hydrology etc.Key words:Yellow River;water harnessing;silt harnessing; sea-filling and land accretion |
| Keywords: | Yellow River water harnessing silt harnessing sea-filling and land accretion |
