The emergence and development of big rivers are calculated by geological age and restricted by meteorological and geological conditions, mainly in flowing water bodies. Humans have developed from living on weeds to today; From relying on domestic and production water provided by rivers to harnessing rivers by construction projects, eliminating four pests and promoting benefits; From the great development of industrialization, which caused water pollution and environmental damage and threatened human survival, to the beginning of paying attention to improving water quality, restoring damaged ecology and restoring the function of rivers, so as to truly realize the harmonious coexistence between people and rivers and realize the sustainable utilization of water resources, which is what human beings should know for their own survival and development today.
Judging from the long history between human beings and rivers mentioned above, I think a healthy river should be not only a river with good ecology, but also a river that benefits human beings and can make sustainable use of water resources.
