Answer:
The Yellow River is the most important water resource for the dry north of China, playing an irreplaceable role in economic development, and agriculture. Since 1960 over 14 dams have been constructed on the river for hydroelectric power, which is vital to northern China's infrastructure.
As an "ecological corridor," the Yellow River, linking the Qinghai-Tibet Plateau, the Loess Plateau, and plains in northern China with severe water scarcity, plays an important role in improving the ecological environment, combating desertification, and providing water supply with the help of water conservancy projects.
Perhaps the two most important geographical features of Ancient China were the two major rivers that flowed through central China: the Yellow River to the north and the Yangtze River to the south. These major rivers were a great source of fresh water, food, fertile soil, and transportation.
