Ecological spur dike for improving aquatic organism habitats of medium and small rivers

Abstract

The invention relates to an ecological spur dike for improving aquatic organism habitats of medium and small rivers. Functions of improving the water environmental quality, building the organism habitats and restoring an ecological system can be effectively achieved. According to the technical scheme, an upper layer dike body, a medium layer dike body and a lower layer dike body are built by gabion boxes, and the periphery of the lower layer dike body is reinforced by wooden piles. Botany cultivating grooves are formed in the upper surfaces of the three layers of dike bodies, an ecological blanket is arranged in the botany cultivating groove of the upper layer dike body, emergent aquatic plants are planted on the ecological blanket, submerged plants B suitable for a shallow water environment are planted in the botany cultivating groove of the medium layer dike body, and submerged plants A suitable for a deepwater environment are planted in the botany cultivating groove of the lower layer dike body. According to the ecological spur dike for improving the aquatic organism habitats of the medium and small rivers, nitrogen and phosphorus nutritive salt level in a water body can be obviously reduced, organic content in the water is reduced, so that the water quality purifying effect is improved, the water body landscape is improved, the water body ecological restoration capacity is greatly improved, and innovation the ecological spur dike is achieved.

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...
