A construction method of artificial bird island structure in wetland park

Abstract

The invention relates to a method for constructing an artificial bird island structure in a wetland park. The method includes transforming an outer contour of an artificial bird island into a zigzag shape to meet the condition that the circumference area ratio PAR index of the artificial bird island is greater than or equal to 5%; constructing a main island area, a meadow area, a shallow water area, a medium and deep water area and a deep water area from the inside to the outside of the artificial bird island and adopting an ecological revetment below the flood level; planting arbor plants, shrub plants, herbaceous plants, bog plants and aquatic plants in the main island area, the meadow area, the shallow water area, the medium and deep water area and the deep water area to form an arbor-shrub-herbaceous-bog-aquatic horizontal plant transition zone; conducting routine maintenance on the plants in the main island area, the meadow area, the shallow water area, the medium and deep water area and the deep water area. The method achieves transformation of the existing island, the overall engineering quantity is small, and the method has the advantages of wide island coastline, multiplehabitat types, good water purification effect, good ecological landscape and low transformation cost.

Description

technical field [0001] The invention relates to the field of ecological environment, in particular to a method for constructing an artificial bird island structure in a wetland park, which is especially suitable for wetland parks in the north with functions of open water surface and rainwater regulation and storage. Background technique [0002] As an important habitat for birds, Bird Island is an important place for birds to forage, inhabit, move and breed. With the vigorous development of nature by human beings, the quality of the natural environment has declined, and the living space of birds has decreased sharply, threatening the migration, survival and reproduction of wild birds, and many rare wild birds are on the verge of extinction. According to the research results of the United Nations research project - "Millennium Ecosystem Assessment", among the many threats to the survival of birds, the habitat degradation or destruction of bird habitats is the most serious thr...

Problems solved by technology

[0004] However, in the actual design, the structure of the above-mentioned bird island is relatively simple, and the water level limit required by various birds has not been fully considered. The analysis of birds' food source plants and habitat plants is unclear, and the contact area between the edge of the bird island and the water surface is limited.
