What management ideas can adapt to the characteristics of small and medium-sized rivers?

The concept of ecological river management can adapt to the characteristics of small and medium-sized rivers.

Ecological river regulation is not a simple river greening, nor an image project or landscape project with the goal of "beauty" and "high grade". It is an organic combination of biology and hydraulic architecture based on ecological theory, which combines human society and natural environment to realize the sustainable development of ecosystem.

Ecological rivers should try their best to maintain the natural state of rivers and the integrity of natural twists and turns, deep pools, shoals and wetlands, so as to slow down the flow rate and improve the flood detention and potential recharge capacity; Greening floodplain and improving flood control and water storage capacity; Try to keep the natural slope protection of plants on the embankment, with the purpose of consolidating the embankment soil with plant roots and greening the river bank.

Principles of ecological river management:

1, coordination principle

In the process of river regulation, relevant aesthetic characteristics should be properly integrated, and systematic design should be carried out along the river to enhance the naturalness and unity of the environment and the river.

2, the principle of naturalness

In the process of river restoration, natural restoration methods and means should be applied as much as possible, and artificial restoration mode should be applied appropriately to fully enhance the river's self-restoration ability and promote the benign development of the river.

3, the principle of economy

In practice, river regulation should be carried out from the economic point of view. In this regard, in the process of regulation, we should reduce the cost as much as possible and promote the sustainable development of nature and economy.
