“黄河之水天上来,奔流到海不复回”,古人曾如此赞美过被我们誉为“母亲河”的这条北方大河。然而时至今日,这“天上来水”的黄河已全然失去“奔流到海”的磅礴气势。事实上,自我国建国以来,黄河的下泄流量从逐年减少到1972年终于断流,从断流20余天到1997年断流226天,“母亲河”已完全失去了昔日的风采。黄河流经中国9省区,从上游到下游,真是几多欢喜几多愁。青铜峡位于黄河上游宁夏回族自治区境内,水量丰富。(图③⑤⑥)而位
“The water of the Yellow River came from the sky and ran to the sea.” The ancients once praised this northern river, which we hailed as “Mother River.” However, up to now, the “Yellow River” has completely lost the momentum of “running to the sea”. In fact, since the founding of our country, the discharge volume of the Yellow River has been gradually reduced from the year to 1972. From the discontinuation of more than 20 days to the interruption of 226 days in 1997, the mother river has completely lost its former style. The Yellow River flows through nine Chinese provinces and autonomous regions, from upstream to downstream, how many happy how many worry. Qingtongxia is located in the upper reaches of the Yellow River in Ningxia Hui Autonomous Region, rich in water. (Figure ③ ⑤ ⑥) And bit
