Method for building ecological slope protection by reasonably mixing and matching spiral shells with water plants

Abstract

The invention discloses a method for building an ecological slope protection by reasonably mixing and matching spiral shells with water plants. The method includes the steps: sequentially building an emergent plant area, an emergent plant and submerged plant mixing area and a submerged plant area on a water and land staggered zone between a bank and a water body, and setting grooves for growth of the plants and the spiral shells on the three areas; planting emergent plants in grooves in the emergent plant area, planting emergent plants and submerged plants in grooves in the emergent plant and submerged plant mixing area at intervals, and planting the submerged plants in grooves in the submerged plant area; throwing the spiral shells into the grooves in the three areas. By the method, the content of nitrogen and phosphorous in the water body can be effectively reduced, organic substrates in mud and sand are changed into inorganic salt, the shading effect of attaching organisms for the submerged plants is decreased, deciduous old leaves of the plants are decomposed, excessive release of nutritive salt after the old leaves are decayed is avoided, the content of phytoplankton in water can be reduced by the spiral shells, and excrements of the spiral shells can facilitate growth of the water plants.

Description

technical field [0001] The invention belongs to the technical field of water body environment, and in particular relates to a method for rationally mixing snail shells and aquatic plants to construct ecological slope protection. Background technique [0002] In recent years, with the rapid improvement of social economy, phenomena such as black and odorous rivers, eutrophication of lake water, and red tides in coastal waters have continuously entered people's field of vision. Water pollution not only seriously affects people's life and production, but also beautifies the visual landscape, and the desertification of the ecotone makes banks more vulnerable to water erosion. With the development of society and economy, people begin to beautify and protect the ecological environment and gradually improve their awareness. In this context, water ecological restoration has quietly emerged. The ultimate goal of water ecological restoration is to build a benign ecosystem. Such as: ...

AI Technical Summary

Problems solved by technology

In addition, some lakes and rivers are difficult to settle due to the extremely small suspended sediment in the water, resulting in turbid water quality all year round and extremely low water transparency, which also poses a serious threat to the restoration of the ecotone ecosystem

Due to low transparency and insufficient light conditions, the growth of submerged plants is also severely inhibited
