Editing Buffer zone (section)

=== Riverbank stabilization ===
When riverbanks are low due to plant roots entering the interior of the riverbank vertically, the sediment of riverbank is affected by the action of said plant roots, and the ability to resist erosion is higher than that without plant roots. But when the riverbanks are higher, the roots of the plants do not penetrate deeply into the soil, and the lakeshore soil is not very strong. Herbaceous plants can play a role to some extent, but in the long term, vegetation buffer zone can effectively solve the problem of water level rise and water erosion.

The adsorption capacity of a buffer zone can reduce the speed of [[surface runoff]] and increase the effective water content of soil. Through increasing [[soil organic matter]] content and improving soil structure, a buffer zone can have a positive effect on soil water storage performance. In addition, plant roots make the soil stronger, withstand waves and rainstorm, mitigate the erosion of riverbanks by [[flood]]s, and effectively control the erosion of the beach.
