Recently, the river environment has been changed significantly as the land use of the river basin has increased and urbanization has progressed. This change in the river environment has been accelerated due to the large-scale civil works for watershed and completion purposes. Inherent natural environment functions have declined.

In addition, water pollution in rivers, as well as the ecosystem density of fish and algae in the river vegetation and rivers as a component of the ecosystem has been reduced and the diversity of habitats has been reduced, the function of ecosystem habitat has declined.

For urban rivers with high density of land use around rivers, the river environment has been modified due to the maintenance of reservoirs and reservoirs, linear maintenance of river channels, and construction of river banks.

For example, concrete revetment blocks physically prevent river water from seeping into the soil layer, which not only regenerates natural wetland vegetation but also changes the water temperature when the shade provided by vegetation disappears. It is extremely severe and loses its function as aquatic benthic, fish habitat and spawning grounds, which in turn feeds around the celestial vegetation and damages the habitat of algae hiding in vegetation bumblebees.
