Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of environmental protection, and in particular to a method for constructing an artificial bird island based on floating grass mats in wetlands of black-bellied whistling ducks. Background Art

[0002] Wetlands are important ecosystems on Earth, with ecological functions such as water purification, flood storage and drought prevention. In recent years, with the acceleration of urbanization and the expansion of human activities, the area of ​​wetlands has gradually shrunk or even disappeared, leading to increasingly prominent problems such as reduced biodiversity and deterioration of the ecological environment.

[0003] As one of the important measures to protect waterfowl, the construction of artificial bird islands has been widely used and developed at home and abroad. Its main purpose is to provide habitats for small waterfowl such as black-bellied whistling ducks, white-crowned ducks, mallards, red-necked ducks, and spot-billed pelicans, thereby maintaining and improving urban biodiversity. Currently, most artificial bird islands use fixed structures, such as cement platforms supported by wooden or concrete piles. This type of fixed artificial bird island is greatly restricted by the water environment and has a high cost, making it difficult to promote and apply.

[0004] Rivers, lakes, ponds and other water bodies in cities not only undertake flood control and drainage, water storage, and microclimate regulation, but are also habitats and shelters for wild animals and plants, and are an important part of the urban ecosystem. Due to long-term pollution emissions and engineering modifications that violate ecological principles, the ecosystems of a large number of urban water bodies are extremely fragile. Floating ecosystems, also known as aquatic ecosystems or planktonic ecosystems, refer to the biological communities that develop on or near the water surface and the environment they depend on. They can create diverse biological habitats in urban rivers, while having the functions of sewage treatment and water quality management, and can also beautify the environment.

[0005] The moorhen is a bird of the genus Moorhen in the family Rakatiidae in the order Gruiformes. It is also known as the red-bone moorhen and the red-crowned moorhen. It is widely distributed in all continents of the world except Oceania and Antarctica, and is distributed in many provinces in China. The moorhen inhabits various wetlands rich in emergent plants, often moving in pairs or small groups, and is good at swimming and diving. Due to its unique morphological characteristics and living habits, the moorhen occupies an important position in the wetland ecosystem.

[0006] Morphological characteristics and construction methods: The top of the head, back of the neck and upper back of the adult black-bellied whistling ...

[0007] Living habits and cultivation methods: Black-bellied whistling ducks often move in pairs or small groups, and are good at swimming and diving. They mainly feed on tender leaves, young shoots, rhizomes of aquatic plants, as well as aquatic insects, worms, spiders, mollusks, etc. When foraging, black-bellied whistling ducks often feed while swimming or wading, and sometimes dive into the water to catch food. This unique foraging method makes black-bellied whistling ducks occupy an important position in the wetland ecosystem. In order to attract black-bellied whistling ducks to come and live and breed, it is necessary to simulate their natural ecological environment in the habitat. Some vegetation such as aquatic plants and grass can be planted to provide a rich source of food and a hidden habitat. At the same time, the water quality should be kept clean and the water level should be kept appropriate to meet the living needs of black-bellied whistling ducks.

[0008] Breeding habits and construction methods: The breeding season of black-bellied whistling ducks is from April to July, and they build nests in shallow water reeds or water grasses. The nests are mostly made of dry reeds and dead grass, and are bowl-shaped. Each nest usually has 6 to 10 eggs, and the eggs are light gray or milky white with reddish-brown spots. The incubation period takes about 19 to 22 days, and the male and female birds take turns to incubate the eggs. When creating a habitat for black-bellied whistling ducks, their breeding needs need to be considered. Some shallow water areas or artificial islands can be set up in the habitat for black-bellied whistling ducks to nest and breed. At the same time, human interference and destruction of their breeding environment should be avoided to ensure that black-bellied whistling ducks can breed and live safely.

[0009] Due to the important position of the moorhen in the wetland ecosystem and the decline in its population, it has been included in the "List of Terrestrial Wildlife with Important Economic and Scientific Research Value under State Protection" issued by the State Forestry Administration of China. In order to protect the moorhen and its habitat, corresponding protection measures need to be taken to maintain ecological balance and biodiversity. These protection measures include strengthening the protection and management of habitats, reducing human interference and destruction, and strengthening publicity and education.

[0041] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] like Figure 1 As shown, the present invention provides a method for constructing an artificial bird island based on floating grass mats in wetlands of black whistling ducks, comprising the following steps:

[0043] (1) Select an address;

[0044] (2) construct floating grass mats;

[0045] (3) preparing planting bags, filling them with a substrate layer, sowing plant seeds into the planting bags and covering them with fine sand for sowing and maintenance, or directly planting the plants in the planting bags;

[0046] (4) After the plants have taken root stably, move the planting bags onto the drifting grass mat to form a natural landscape.

[0047] Specifically,

[0048] In step (1), the site should be far away from areas with frequent human activities, such as residential areas, industrial areas or traffic arteries, to reduce noise and interference of human activities on birds and ensure a safe and quiet breeding environment for birds. The site for constructing an artificial bird island should be selected in a water area with an area of ​​not less than 200 square meters, such as a river, lake, urban artificial lake, landscape water body, etc.

[0049] In step (2), a floating grass mat is constructed by combining a floating board and a palm mat. Figure 2The specific contents of constructing the floating grass mat include: using wooden strips or bamboo strips to fix logs or bamboo tubes into floating boards, the cross-section of the logs or bamboo tubes is round or oval, with a diameter of 10cm-25cm and a random length. In some specific embodiments, see Figure 3 and Figure 4 , logs or bamboo tubes 6 are assembled into floating boards 1 through mortise and tenon structures. The size of the floating board can be adjusted according to needs. Palm mats 2 are placed on the floating board 1. In order to ensure that the planting bags and planting soil can be on the floating board for a long time, the palm mats need to cover the holes of the floating board. Figure 6 The palm mat is woven from palm fibers with a density of 65kg / m 3 ~90kg / m 3 , thickness 2-5cm (see Figure 5 ).

[0050] In step (3), a planting bag is prepared. The planting bag is made of a degradable material, sealed at both ends, and is cylindrical with a diameter of 25-35 cm. The planting bag is provided with air holes and is filled with nutrient soil, sand or peat moss as a substrate layer. Plant seeds can be sown into the planting bags to cultivate hydrophilic plants such as water coriander, rush, foxtail grass, shuttle grass, spotted grass, dogtooth grass, goose tendon grass, woodlouse grass, purslane, water chestnut, calamus, water plantain, water celery, water polygonum, pseudo-golden grass, loosestrife, iris, lily, phoenix bamboo, yellow iris, Mars flower, kidney fern, blue flower grass, spring feather, strelitzia, hanging bamboo plum, variegated spider plant, green leaf spider plant, Polygonum capitata, Khan Palace Autumn, smooth sailing, water chestnut, red dragon grass, sea lettuce, pondweed, centipede grass, wild rice squash, Alisma orientalis, etc., or hydrophilic plants can be directly planted in the planting bags to shorten the cultivation time.

[0051] In step (4), after the plants have taken root stably, planting bags are set at the edge of the floating grass mat, and the area above the palm mat near the center of the floating board is covered with nutrient soil 4 and mixed wet meadow 5 in sequence, and shallow-rooted plants are planted. At the same time, planting troughs are formed between the planting bags, and nutrient soil 4 and mixed wet meadow 5 are covered in sequence in the planting troughs, and shallow-rooted plants are planted. The effect diagram of the constructed wetland floating grass mat artificial bird island is shown in FIG. Figure 7 .

[0052] Placing planting bags at the edge of the floating grass mat can firstly control the weight of the floating meadow, which is beneficial to the balance of the meadow; secondly, it can prevent the loss of planting soil on the meadow; thirdly, the planting bags in the edge area are mainly planted with taller and denser hydrophilic plants, which can provide a safe environment for small and medium-sized birds such as black-bellied whistling ducks. At the same time, planting shallow-rooted plants in other positions of the floating grass mat is beneficial for small and medium-sized birds such as black-bellied whistling ducks to build nests and avoid natural enemies.

[0053] Furthermore, multiple floating grass mats can be made as needed and combined together to form a large-scale artificial wetland ecological environment.

[0054] Since 2021, the construction plan of the present invention has been implemented in the water area of ​​the east gate of Kunming Cuihu Park. The constructed wetland floating grass mat artificial bird island provides a habitat for black-bellied whistling ducks to rest, forage, reproduce, and show off. It also has the function of ecological restoration and can beautify the environment.

[0055] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
