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.

Embodiment Construction

[0023] Please refer to attached Figure 1-3 , the present invention is a landscape lake bottom waterscape system, which mainly consists of landscape lake, plant root fixed net, double-layer geotextile non-woven fabric, water level surface, natural ground, nutrient base for planting aquatic plants, underwater landscape pebbles, microbial attachment materials, and lake bottom aquatic products. It is composed of landscape plants, snails and other benthic animals, ornamental fish, springs, etc. The artificial lake is excavated (with a depth of 500-700mm) in the waterscape area at the bottom of the lake, and the bottom of the artificial lake is leveled and compacted with plain soil, and then paved on the bottom. One-layer geotextile non-woven fabric, planting aquatic plant nutrient base on the double-layer geotextile non-woven fabric, setting plant root fixing net on the nutrient base for planting aquatic plants, planting and fixing aquatic plants at the bottom of the lake, and fina...
