River microhabitat improving system and method

Abstract

The invention relates to a river microhabitat improving system and method. The problem that an existing river habitat is single can be effectively solved. According to the technical scheme, an aquaticplant improving system is formed by aquatic plant growing regions where aquatic plants are grown. The aquatic plant growing regions are arranged at still water areas between all spur dikes of spur dike groups and slopes of all the spur dikes. A water flowing improving system comprises shoals, a gravel group and deep grooves. The shoals are arranged in the still water areas between all the spur dikes of the spur dike groups. The aquatic plant growing regions are arranged on the shoals of the still water areas. The shoals are provided with the corresponding deep grooves which stretch into and penetrate out of the gaps between all the spur dikes of the spur dike groups in a zigzag mode. By means of the river microhabitat improving system and method, the still water areas can be made movable,water circulation is improved, water mobility is also improved, the dissolved oxygen content is increased, planted aquatic plants are subjected to photosynthesis to release oxygen, water can be circulated to increase the oxygen contents of water areas between the spur dike groups, and therefore the water quality is improved, and the scheme is an innovation of river microhabitat improving systemsand methods.

Description

1. Technical field [0001] The invention relates to the field of river environment, in particular to a system and method for improving river microhabitats. 2. Background technology [0002] Spur, also known as "floating dam", is a river channel regulation structure that extends into the channel orthogonally or obliquely to the river bank. The end of the dam is connected to the embankment in a "T" shape. Groove dams can be divided into submerged dams or non-submersible dams. When designing, the crest of submersible dams can pass through water, while the crest of non-submersible dams cannot pass through water. The dam body that is permeable is called a permeable spur dam, and the impermeable one is called an impermeable spur dam. The impermeable spur dam has a strong effect of controlling water flow, and is composed of stone materials, soil materials, concrete prefabricated components or sunken row paving. The permeable spur dike can lift part of the water flow away from the...
