Embodiment

[0017] Such as figure 1 Shown, the construction of wetland artificial ecological island of the present invention is to be the construction waste (mixture of masonry and concrete body) of 8-12cm and river, river, The pond mud is piled up into an island body with a volume ratio of 2:3. During the accumulation process, it is leveled and rolled layer by layer. The height of the island body can be set according to the actual environment. Around the top of the island body, stones 1 are used to build the periphery with cement mortar, and xeric or wet plants (such as weeping willow, black locust etc.) are planted in the middle. On the island slope, a frame is built with stones 1 and cement mortar for curing. The structure of the frame is as follows: figure 2 shown, consisting of a single cross-shaped frame. The shape of the frame can also be as image 3 The shown polygon is provided with reinforcement stacks 7 on the frame, and the shape of the frame can also be a circle, a rhombu...

Abstract

The invention provides a method for constructing an artificial ecological island in wetland, which is to stack building waste and river mud or pond sludge into an island body according to the volume ratio of 2 to 3 on the basis of the prior natural island or a hard foundation in the wetland, and level and grind the island body layer by layer during the stacking; the circumference on the top of the island body is placed by stone and cement mortar, and xerophytes and hygrophytes are planted in the middle on the top of the island body; the stone and the cement mortar are used for placing vertically and horizontally frame bodies on the circumferential island slope of the surface of the island body; waste concrete bodies or gravel is filled into spaces of the frame bodies; slurry is sprayed or poured on the waste concrete bodies or the gravel, and the thickness of the slurry can cover the gravel or rubble; hygrophytes, emergent aquatic plants and submerged plants are planted on a slurry layer; and larger plants are planted before the waste concrete bodies or the gravel is filled. The method has low cost, is convenient to construct, is favorable for conserving water and soil, reduces the gradation degree of the island body, and makes a wetland ecosystem maintain stable.

Description

technical field [0001] The invention relates to a method for constructing a wetland artificial ecological island, and belongs to the technical field of water body purification and restoration. Background technique [0002] An island refers to land surrounded by water in rivers and lakes, and it plays a very important role in wetlands, especially under the circumstances that the current wetland environment has been damaged to varying degrees. The island in the wetland can change the direction of the water flow, and the wetland will not dry up when the water volume decreases; the island slope is the medium between the island and the water, which provides a place for microorganisms to multiply while absorbing suspended matter; the existence of the island also It provides a wide living space for amphibian wetland animals and different types of plants, which makes the ecosystem on the island in a stable and balanced state, which is conducive to the sustainable development of wetl...
