Landscape lake bottom waterscape system and construction method thereof

Abstract

The invention discloses a landscape lake bottom waterscape system. The system comprises a landscape lake, a plant root system fixing net, a double-layer geotechnical non-woven fabric, an aquatic plantplanting nutrient medium, underwater landscape pebbles and a microorganism attachment material, wherein the double-layer geotechnical non-woven fabric is laid on the landscape lake bottom layer; an aquatic plant nutrient medium is laid and planted on the double-layer geotechnical non-woven fabric, a plant root system fixing net is arranged on the aquatic plant nutrient medium, a fountain is further arranged at the bottom of the landscape lake, the fountain generates induced flow, up-and-down convection of gushing spray eliminates temperature difference, and the water surface of the landscapelake is located at the position 100-150 mm below the natural ground. The invention further discloses a construction method of the landscape lake bottom waterscape system. According to the invention, the problem of artificial lake eutrophication easily caused by external pollution afflux is solved; the content of pollutants such as nitrogen, phosphorus and heavy metal in the water body is reduced,nutrient elements absorbed by the bottom layer can be absorbed by plants during growth, the self-purification capacity of the water body is well achieved, the maximization of the ecological purification capacity is achieved, and the water quality effect of the water body is guaranteed in an all-around mode.

Description

technical field [0001] The invention belongs to the technical field of landscape lake bottom waterscape construction engineering, and in particular relates to a landscape lake bottom waterscape system and a construction method thereof. Background technique [0002] With the improvement of people's living standards and the development of cities, artificial lakes for people's leisure and entertainment have been built in many cities. The artificial lake not only beautifies the environment, but also can regulate the temperature and reduce the greenhouse effect. Regardless of the construction of artificial lakes in the early stage or the maintenance of water quality in the later stage, they should stand at the height of environmental protection and ecology, implement resource conservation, people-oriented, and conform to the principles of health and comfort, so as to achieve the harmonious development of human beings and nature. [0003] As the receiving body of urban surface ru...

AI Technical Summary

Problems solved by technology

[0004] In view of this, the present invention proposes a landscape lake bottom waterscape system and its construction method, which solves the problem that the influx of external pollution easily leads to eutrophication of the artificial lake, reduces the content of pollutants such as nitrogen, phosphorus and heavy metals in the water body, and at the same time The nutrients absorbed by the bottom layer can be absorbed by plants for growth, and it also solves the self-purification ability of the water body, realizes the maximization of the ecological purification ability, and guarantees the water quality effect in an all-round way
