Technical Field

[0001] The utility model relates to the technical field of river ecological technology, and more specifically to an ecological buffer zone for intercepting and purifying a river. Background Art

[0002] In today's river management, riverbank soil protection is mostly achieved by setting up buffer zones on the river bank and planting different plants according to the environmental conditions at different locations in the buffer zones. It is an important part of nutrient management, sediment and soil erosion control, and protection of freshwater resource environment systems. It plays an important role in controlling riverbank erosion, intercepting surface runoff sediment and nutrients, protecting river water quality, regulating water temperature, providing habitats for aquatic and terrestrial animals and plants, maintaining river biodiversity and ecosystem integrity, and improving riverbank landscape quality.

[0003] In reservoirs, the seasonal fluctuations in water levels will cause large changes in the water level in the drawdown zone. When the water level changes for too long, the vegetation survival rate in the drawdown zone will be poor, and replanting is often required, which is time-consuming and labor-intensive, and therefore needs to be improved. Utility Model Content

[0009] As a further improvement of the present invention, the upper end surface of the first support frame is provided with culture soil, and the culture soil is made flush with the vegetation areas on both sides, and the water storage groove forms a water gap corresponding to the lower end surface of the first support frame.

[0010] As a further improvement of the present invention, a second support frame is provided in the water storage groove, and a plurality of water outlet holes are arranged on the side wall of the second support frame.

[0011] As a further improvement of the present invention, the second support frame is symmetrically provided with arc-shaped intercepting surfaces.
