An ecological spur dam aimed at improving the habitat of aquatic organisms in small and medium rivers

Abstract

The invention relates to an ecological spur dam for improving the habitat of aquatic organisms in small and medium-sized rivers, which can effectively exert its functions of improving water environment quality, building biological habitats and restoring ecological systems. The technical solution is that the upper dam body, the middle dam body and the The lower dam body is all constructed of gabion nets, and the periphery of the lower dam body is reinforced by wooden piles. The upper surface of the three-layer dam body is equipped with plant cultivation tanks, and the plant cultivation tanks of the upper dam body are equipped with ecological blankets. Emergent plants are planted, submerged plants B suitable for shallow water environment are planted in the plant cultivation tank of the middle dam body, and submerged plants A suitable for deep water environment are planted in the plant cultivation tank of the lower dam body. The present invention can significantly reduce the water quality. The level of nutrient salts such as nitrogen and phosphorus reduces the content of organic matter in the water, thereby improving the effect of water purification, improving the landscape of the water body, and greatly improving the ecological restoration ability of the water body. It is an innovation on the ecological spur dam.

Description

technical field [0001] The invention relates to the technical field of aquatic organism habitat improvement, in particular to an ecological spur dam oriented to the improvement of aquatic organism habitat in small and medium-sized rivers. Background technique [0002] Traditional water conservancy and river improvement projects only consider flood control, water supply, and soil and water conservation, making the original meandering river straight or broken, hardening the riverbed, and discontinuing the longitudinal direction, changing key physical conditions such as flow, velocity, and riverbed shape. factor. Changes in all these environmental elements will have a serious impact on river habitats, resulting in the degradation of river habitats, greatly reducing biodiversity, and ultimately leading to a series of environmental problems such as the loss of natural functions of rivers and the extinction of biological species. In view of the important position of rivers in the...
