A self-purifying artificial lake with constant water level slope ecological layout and its construction method

Abstract

The invention discloses an ecological layout of a constant water level slope of a self-purifying artificial lake, which includes a water source conservation and catchment area, a shallow water level floating leaf plant purification area, a slope surface amphibian plant embellishment area, an ecological recreation and appreciation area around the lake, and constant water level pollutants composition of the interception zone. Among them, the water conservation catchment area is located in the upstream of the water source, and the planting of wetland plants plays a role of water conservation; the shallow water level floating leaf plant purification area is usually below the normal water level, and the lake water is purified and decontaminated by planting floating leaf plants; The area is above the water level; the ecological recreation area around the lake is located around the slope top lake, and the surrounding landscape is carefully created by planting landscape trees and flowering shrubs; the downstream outlet is built with a constant water level pollutant intercepting dam to ensure that the water level of the artificial lake is constant and stable. Contaminant retention. The technical scheme of the present invention not only plays an important role in water source cleanliness and ecological improvement in the artificial lake area through careful construction and plant design, but also has remarkable features of ecology, greening, three-dimensionality, and synergy.

Description

technical field [0001] The invention relates to a self-purifying artificial lake constant water level slope ecological layout and construction method, which belongs to the technical field of urban landscaping and landscape construction. Background technique [0002] With the rapid development of my country's economy and the acceleration of urbanization, the creation of urban and rural environmental landscapes has attracted increasing attention. Especially with the increasing number of urban population, the buildings are becoming more and more dense, and the limitation of urban gardens and green spaces is becoming increasingly prominent. Appropriate and compact waterfront greening can not only achieve landscaping and block separation, but also achieve special effects of ecological restoration and landscape diversification, increasing the amount of greenery in a very limited urban space, and bringing benefits to local residents and the past. Lu Ke has a fresh and elegant aest...

Problems solved by technology

[0006] The traditional lake greening structure has a single type, most of which are pure hard structures or cement retaining walls, and some water-resistant trees are simply planted on the periphery. The slope greening and structural layout are rigid and rigid, and the landscape effect is not ideal.

The simple lake surface structure and slope protection layout cannot meet the limited control of lake water accumulation. It often overflows during the flood season and causes waterlogging, and it dries up in winter. Aquatic fish cannot survive and reproduce.

More importantly, traditional lake slopes blindly pursue firmness and corrosion resistance, and cannot provide space and conditions for waterfront animals and plants to live and reproduce. Biodiversity maintenance is difficult to achieve, which is not conducive to water and soil conservation and the modern city's environmental beautification. requirements, and is not conducive to the long-term stability and health of the urban ecosystem
