Description

Technical Field

[0001] The embodiments of the present invention relate to the field of environmental protection technology, and in particular to an urban wetland floating bird island based on egrets and a construction method thereof. Background Art

[0002] With the continuous advancement of urbanization, the ecological environment of many cities in my country has been damaged to varying degrees. As one of the important ecosystems, wetlands have ecological functions such as regulating climate, purifying water quality, and conserving water sources. They are one of the areas with the richest biodiversity and an important habitat and migration stop for birds. Therefore, creating artificial wetlands is of great significance to improving the quality of urban environment and restoring natural ecosystems.

[0003] At present, the surface of deep water areas of artificial water bodies in urban parks in China is an ecological blind spot, and deeper waters are not suitable for the survival of egrets. How to effectively use this area for ecological restoration and provide support for the restoration of urban biodiversity is an issue to be solved. Due to the impact of human activities, the number of wild animals in cities is gradually decreasing, while egrets are more common in urban parks, have lower requirements for living space, and are more adaptable. However, artificial water bodies in urban parks are often more than 2 meters deep and cannot provide a suitable living environment for these small herons. Due to the lack of suitable habitats, they usually choose to move in waters far away from urban parks. This is not only not conducive to the protection of wild animal and plant resources in the city, but may also cause conflicts and competition between species, affecting the balance and development of the entire ecosystem.

[0004] Little Egret: There are 13 species of birds in the genus Egret, including the Little Egret, the Middle Egret, the Great Egret and the Yellow-billed Egret, all of which have completely white feathers and are commonly known as "white egrets". Due to the important position of egrets in the ecosystem and the decline in their population, egrets have been included in the "National List of Terrestrial Wildlife with Important Economic and Scientific Research Values". In addition, in some places, egrets are also listed as key protected wild animals.

[0005] Little egret, middle egret, great egret, yellow-billed egret: often live in swamps, fields, dams, coasts and other water environments, especially in low-altitude areas such as lakes, ponds, rivers and tidal flats and other wetland ecosystems. The morphological characteristics, living habits, breeding habits and other aspects of the above four egrets are introduced as follows:

[0006] 1. Morphological characteristics: The egret is of medium size, with a body length of about 45-90 cm. The weight range is between 320-650 grams. There is no obvious difference in morphology between male and female birds, and both have yellow toes. The egret's plumage is mainly white, and special ornamental feathers and hooded feathers grow during the breeding season. There are two slender ornamental feathers on the head, and long hooded ornamental feathers on the back and chest. These ornamental feathers will fall off after the breeding season. The egret's beak is black or yellow, but it turns pink during the breeding season. The iris is yellow or blue, which varies according to the season and individual differences.

[0007] 2. Living habits and construction methods

[0008] 2.1 Eating habits: Egrets mainly feed on small fish, shrimps, frogs, aquatic insects and other small animals. They often stand still in shallow water for a long time, staring at the water surface with sharp eyes. Once they find food, they quickly use their beaks to catch it. The hunting method of egrets makes them occupy an important position in the aquatic ecosystem. Therefore, when creating a habitat for egrets, factors such as the food chain and food quantity in the area need to be considered.

[0009] 2.2 Migration habits: The migration habits of egrets vary from region to region. In China, egrets are widely distributed in the north and south; abroad, they can be found in a wide range of areas in Eurasia, Southeast Asia and Africa. Usually egrets that breed in the south do not migrate and are resident birds; while egrets that breed in cold places such as the north will migrate to the south for wintering. The migration time is mostly in late March and early April in spring and early to late October in autumn. During the migration period and in winter, egrets often gather in large groups, sometimes mixed with other birds.

[0010] 2.3 Resting habits: They forage in the water during the day and rest in trees or other safe places at night. Therefore, when creating a habitat for egrets, their migration and nocturnal roosting habits need to be considered comprehensively.

[0011] 3. Breeding habits and construction methods: The breeding season of egrets is usually from April to July. Before the breeding season, egrets will start looking for a suitable nesting location and build nests. The nests are usually chosen in trees or bushes near waters, and sometimes they choose to build nests on the ground. The nesting materials are mostly made of dry branches, dead grass, etc. Each nest usually has 3-6 eggs, and the color of the eggs is blue-green or light brown. The incubation period takes about 24-26 days, and the male and female birds share the responsibility of incubating eggs and raising chicks. During the breeding period, in order to protect the safety of the nest and the young birds, egrets will become very alert and ferocious. Therefore, when creating a habitat for egrets, it is necessary to try to avoid interfering with their breeding activities and provide a safe nesting environment. Summary of the invention

[0012] To this end, an embodiment of the present invention provides a floating bird island and a construction method in an urban wetland for egret birds. The present invention is constructed based on the morphological characteristics, living habits, breeding habits, etc. of four egret birds to protect egrets and their habitats and maintain ecological balance and biodiversity.

[0040] 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.

[0041] Example 1

[0042] This embodiment provides an urban wetland floating bird island based on egret birds, see Figure 1 The urban wetland floating bird island includes an inner circle 1 and an outer circle 2 of the floating bird island. The inner circle of the floating bird island includes a floating carrier and standing piles, and the floating carrier is provided with a cultivation trough. Specifically, the inner circle of the floating bird island is a fixed frame composed of standing piles and floating carriers (recyclable floating materials), and a cultivation trough 3 is arranged on the floating carrier, and cattail or calamus is planted in the cultivation trough. The number of standing piles is flexibly designed according to the size of the water area on site, but it must be ensured that there is at least a 4.5-meter-wide distance from the shore to meet the safety distance requirements of animals.

[0043] The inner and outer circles of the floating bird island are composed of floating carriers (recyclable floating materials) and cultivation troughs, in which hydrophilic plants such as irises or water onions are planted. The total area required for the construction of the entire floating bird island is not less than 100 square meters.

[0044] Buckles 4 and hollow fixing rod holes 5 are provided at the edge of the floating carrier, wherein the buckles are used for fixing and connecting the floating carriers, and the hollow fixing rod holes are used for inserting fixing rods 6 that fix the floating bird island on the water surface and are also used for setting standing piles in the bird island.

[0045] The bird island is composed of an inner circle and an outer circle. The inner circle is equipped with more standing piles, and the outer circle is equipped with more floating carriers. The inner circle meets the needs of some egrets to stand alone, and the outer circle is densely planted with plants to meet the needs of some small and medium-sized egrets to live in groups and build nests.

[0046] The area of ​​the inner circle of the floating bird island can be designed into any shape or size according to the size of the water area on site, and sufficient standing piles can be placed inside to provide rest support for egrets as needed. The main function of the outer circle of the floating bird island is to provide a relatively independent space for the growth of irises or water plantains, thereby forming a living and habitat space for egrets.

[0047] Example 2

[0048] This embodiment provides a method for constructing an urban wetland floating bird island based on egrets, comprising the following steps:

[0049] Step 1: Site selection. This plan is suitable for wide waters such as urban parks, rivers, lakes and deep water areas with a depth of more than 2 meters, and the distance between the outer perimeter and the shore cannot be less than 4.5 meters. Ensuring sufficient distance is conducive to reducing human interference and enhancing a sense of security, which is helpful for egrets to build nests. The total volume of the inner circle and the outer circle of the floating bird island is not less than 100 square meters, and the area ratio of the inner circle and the outer circle of the floating bird island is 1:1.5-1:2.

[0050] Step 2: Set up fixed piles 6. The function of the fixed piles is to ensure the stability of the floating materials in the inner circle of the floating bird island, which is convenient for the egrets to build nests in the later period. The standing piles provide support for the egrets to rest. The fixed piles are made of logs or bamboo with a diameter of 20-35 cm, which are directly inserted into the bottom of the water body and fixed. The length depends on the water depth of the selected area, ensuring that it is 1.2-1.5 meters above the water surface.

[0051] Step 3: Plant hydrophilic plants on the floating material. The inner circle of the floating bird island is planted with cattail or calamus, and the outer circle of the floating bird island is planted with iris or water plantain. You can choose to plant a single plant or a mixture of multiple plants.

[0052] Step 4: Set up floating materials in the inner circle of the floating bird island, fix the fixed piles to the floating materials, connect the floating materials through buckles, and install them according to the designed area of ​​the inner circle of the floating bird island.

[0053] Step 5: Set up the standing pile 7. The main function of the standing pile is to provide rest support for the egrets and to serve as a support for nesting in the future. Therefore, the standing pile is made of logs or bamboos with a diameter of 12-20 cm. The standing pile is directly inserted into the bottom of the water body and set at intervals of 80-120 cm. The horizontal bar is made of logs or bamboos with a diameter of 3-7 cm.

[0054] Step 6: Set up floating materials within the outer circle of the floating bird island. First, set up the floating materials around the fixed piles, and connect the floating materials through joints, and lay them according to the required area.

[0055] In the above technical solution: polyester fiber is used to make the floating material. At the same time, the water environment of different cities is quite different, so the materials are selected to ensure durability and pollution-free. In addition, in order to increase stability, the number of fixed piles can be appropriately increased. Finally, it should be noted that environmental protection measures should be taken during the construction process to ensure that no pollution sources enter the water and affect the balanced development level of biodiversity.

[0056] 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.
