The Chinese people are industrious and great people in the world. In order to meet the needs of population growth for food and a good ecological environment, the Chinese people have worked one after another to control river disasters and water disasters, and established many great water and soil conservation projects, among which the most famous ecological projects are the Dujiangyan project and the Three Gorges dam. After years of operation and practice, it has been proven that the Jiangyan project and the Three Gorges Dam not only irrigate a large area of farmland downstream to meet the needs of people's irrigation, food security and agricultural development, but also meet the needs of ecotourism. It shows that the Dujiangyan project and the Three Gorges dam are high-quality and sustainable management of water and soil conservation projects, but also outstanding ecological projects and public utilities, which will play a more important role in high-quality development of the new era of China.

Key words: Chinese nation; Dujiangyan project; Three Gorges dam; food security; high-quality sustainable water and soil conservation projects; Ecological engineering.
