Problems solved by technology

Moreover, the soil salinization in such areas is high, bank protection measures lead to a large amount of hardening of the river bank soil, and few green plants can adapt to this harsh habitat condition, so that the vegetation types currently constructed for river bank management are relatively monotonous. The ecological landscape and water purification ability are not strong
[0003] Nowadays, herbaceous plants are mostly used in the treatment of rivers and coasts, and most of them are restored in water bodies. However, because the pollutants in the river flow with the water flow, the polluted area is large, and the ability of aquatic plants to absorb pollutants in water is limited. Unsatisfactory removal
In recent years, there has been a method of constructing a buffer zone on the river bank for ecological management of river water, but there are problems such as relatively single plant structure and relatively large limitations in preventing and controlling agricultural non-point source pollution. Therefore, how to combine the characteristics of northern regions and the natural environment of riparian zones It is a technical problem to be solved urgently by those skilled in the art to screen vegetation by habitat and provide a method for constructing a riparian vegetation buffer zone with better ecological management effect.

Abstract

The invention discloses a construction method of a riverbank vegetation buffer zone. The construction method comprises the following steps of: selecting an area 10-100m away from a riverbank as a buffer zone construction area, adjusting the earth surface gradient of the buffer zone construction area, and sequentially arranging a reinforced matrix zone, an arbor zone and a shrub and grass zone according to the sequence of the riverbank from far to near; and the reinforced matrix belt is composed of soil and activated carbon. According to the buffer zone constructed by the method, the ammonia nitrogen content in river water and surface runoff is reduced, and meanwhile, the organic matter content in soil is increased.

Description

technical field [0001] The invention relates to the technical field of ecological protection, in particular to a river bank vegetation buffer zone and a construction method. Background technique [0002] In our country, the rivers in many areas are artificially excavated, and tidal flats are formed around them. Sewage containing a large amount of pollutants enters the rivers, seriously damaging the river ecosystem. Moreover, the salinization of soil in such areas is high, bank protection measures lead to a large amount of hardening of river bank soil, and few green plants can adapt to this harsh habitat condition, so that the vegetation types currently constructed for river bank management are relatively monotonous. The ecological landscape and water purification ability are not strong. [0003] Nowadays, herbaceous plants are mostly used in the treatment of rivers and coasts, and most of them are restored in water bodies. However, because the pollutants in the river flow w...
