黄河介绍：:1、黄河，中国北部大河，全长约5464公里，流域面积约752443平方公里。世界第五大长河，中国第二长河。
The Yellow River, a great river in northern China, is about 5464 kilometers long and has a basin area of about 752443 square kilometers. The fifth longest river in the world and the second longest river in China.
2、黄河北源发源于青海省青藏高原的巴颜喀拉山脉支脉查哈西拉山南麓的扎曲，南源发源于巴颜喀拉山支脉各姿各雅山北麓的卡日曲，西源发源于星宿海西的约古宗列曲。呈“几”字形，自西向东分别流经青海、四川、甘肃、宁夏、内蒙古、陕西、山西、河南及山东9个省（自治区），最后流入渤海。
The northern source of the Yellow River originated from Zaqu at the southern foot of Chahasila Mountain, a branch of the Bayan Hara Mountains on the Qinghai-Tibet Plateau. The Southern source originated from Kajiqu at the northern foot of the various Yashan Mountains of the Bayan Hara Mountains, and the Western source originated from the Argumentary Zongliequ at the Western foot of the Star Hara Mountains.
In the shape of "Ji", it flows through Qinghai, Sichuan, Gansu, Ningxia, Inner Mongolia, Shaanxi, Shanxi, Henan and Shandong provinces (autonomous regions) from west to east, and finally flows into the Bohai Sea.
3、黄河是中华文明最主要的发源地，中国人称其为“母亲河”。每年都会生产十六亿吨泥沙，其中有十二亿吨流入大海，剩下四亿吨长年留在黄河下游，形成冲积平原，有利于种植。
The Yellow River is the most important birthplace of Chinese civilization. The Chinese call it the "Mother River". Every year, 1.6 billion tons of sediment will be produced, of which 1.2 billion tons will flow into the sea. The remaining 400 million tons will remain in the lower reaches of the Yellow River for a long time, forming an alluvial plain, which is conducive to planting.
优点：
1、黄河上建立了数座水电站，可以发电供人类使用。
Several hydropower stations have been built on the Yellow River to generate electricity for human use.
2、调节河流附近生态环境与气候。
To regulate the ecological environment and climate near rivers.
3、可以引水灌溉周边农田。
Water can be diverted to irrigate surrounding farmland.
黄河的孕育、诞生、发展受制于地史期内的地质作用，以地壳变动产生的构造运动为外营力，以水文地理条件下本身产生的侵蚀、搬运、堆积为内营力。在成河的历史过程中，运动不息，与时俱进。黄土高原的水土流失与黄河下游的泥沙堆积在史前地质时期就在进行，史后受人类活动的影响与日俱增。
根据多方面的研究，古黄河有三个发展阶段：第三纪至第四纪的早更新世为古黄河孕育期。第四纪中更新世（距今115万年～10万年）古黄河诞生成长期。晚更新世（距今10万年～1万年）黄河形成海洋水系。
