Description

Diversified habitat system for restoring river and lake ecological system

Technical Field

The utility model relates to a diversified environmental system for river lake ecosystem is restoreed.

Background

With the rapid development of the urbanization and industrialization process, a large amount of pollutants such as organic matters, heavy metals, nitrogen and phosphorus nutrient salts and the like are discharged into rivers, lakes and other water areas, and a series of non-ecological measures such as urbanization, river channel narrowing, linearization, abruptness, river filling and road building are implemented, so that a plurality of rivers and lakes increasingly show the tendency of degradation, deterioration and morbidity, such as blue-green algae outbreak, river blackness and odor, duckweed, water hyacinth flooding, river and lake non-biological treatment and the like. The increasingly serious pollution condition of rivers and lakes threatens the production and life of people and severely restricts the high-level and high-quality development of the urbanization process. After the river and lake pollution is comprehensively treated for more than ten years, the pollution trend of the river and lake is generally restrained, but the recovery and reconstruction of the ecological system of the river and lake are far more important.

In the practical process of restoring and reconstructing the river and lake ecosystem, the aquatic plants serving as a key ring in the river and lake ecosystem are used as primary producers, not only can absorb nitrogen and phosphorus nutritive salts by themselves to maintain growth needs, but also can be used as a constituent element of a habitat in the water area ecosystem to provide a place for breeding life for other organisms and microorganisms, and therefore, the aquatic plants become a main means in the restoration engineering of the river and lake ecosystem. At present, the habitat constructed by the aquatic plants mainly comprises an underwater forest community, a water surface floating island community, a bank land and water staggered zone community and the like. The water surface floating island community is used as a main means for landscape decoration in a water body, the contact with the water body is limited, and the habitat space for creating the suitable microorganism propagation is limited; the construction of the underwater forest community has restriction factors, such as requirements on water illumination, transparency and a substrate, the problem that the transparency is low in polluted rivers and lakes and the requirement for plant survival is difficult to meet exists, the sludge at the bottom of the polluted rivers and lakes is thick and mostly in an anaerobic state, so that the construction of the underwater forest is difficult to maintain, particularly, a pollution source is not completely intercepted, sewage continuously enters, and the underwater forest is destroyed once when one sewage or one rainstorm exists; the bank land and water staggered zone community has limited space due to steep and hard urban river channels, can only be generally distributed within the range of water depth less than 50cm along the bank, and cannot be positioned in river and lake water bodies with different water depths according to requirements.
