Problems solved by technology

[0005] 2. Insufficient food resources for black-necked cranes in wintering habitat
[0007] 3. The impact of climate makes Caohai no longer suitable for wintering habitat of black-necked cranes
At present, the artificial construction method of the wintering habitat of the "bird panda" black-necked crane is still blank, and the task of restoring and rebuilding wetland habitats and habitats that have been destroyed by reclamation is very heavy. important task

Embodiment 1

[0043] This embodiment provides a wintering artificial habitat for black-necked cranes, including an artificially constructed area 1 for night habitat. Select a distance of more than 500m from roads and buildings, and an area of ​​flat land greater than 1km 2 The above abandoned land is used as artificial construction area; floodplains, wide and shallow rivers, and wintering habitats for black-necked cranes around reservoirs are preferred. Such as Napahai Nature Reserve in Yunnan, Huize Nature Reserve in Yunnan, Dashanbao Nature Reserve in Yunnan, Yarlung Zangbo River Middle Reservation in Tibet, Serin Co Nature Reserve in Tibet, Caohai in Weining, Guizhou, Niyang River Confluence in the lower reaches of the Yarlung Zangbo River The overwintering habitats of black-necked cranes are actually used by the black-necked cranes such as the estuary and the surrounding areas of the Daqiao reservoir. However, the above-mentioned areas are destroyed by engineering construction and other...

Embodiment 2

[0047] Further improvement on the basis of Example 1, the overwintering artificial habitat for black-necked cranes also includes the natural enemy avoidance artificial construction area 2 and the foraging artificial construction area 3; the night resting ground artificial construction area 1 is located on the artificial island in the water, The artificial construction area 3 of the foraging ground is located on the water bank near the artificial construction area 1 of the nocturnal resting place, and the artificial construction area 2 of the natural enemy avoidance area is located at the inlet between the artificial construction area 1 of the night resting ground and the artificial construction area 3 of the feeding ground .

[0048] The depth of the water inlet between the artificially constructed area 1 of the night resting place and the artificially constructed area 3 of the foraging places on both sides is 1m to 1.5m, and the width is 12m to 15m; Low, easy-to-grow aquatic ...

Embodiment 3

[0052] This embodiment provides a method for building an artificial habitat for black-necked cranes overwintering, including the following steps: selecting floodplains, wide and shallow rivers, and reservoirs that are more than 500m away from roads and buildings, and there are flat and abandoned land around them as artificial wintering habitats. Areas; divide and construct the artificially created areas of night resting places, artificially created areas of avoiding natural enemies and artificially created areas of foraging places to artificially create overwintering habitats. In addition, according to the migration season (spring and autumn) and the differences in the dominant bird communities in winter, natural resources can be rationally used to adjust the elements of wetland habitats by human intervention, and 3-3- With a tidal elevation of 4 meters, a certain buffer area can be opened in some reed planting areas, such as bare land and shallow ponds, to facilitate the habit...

Abstract

The invention discloses an artificial black-necked crane overwintering habitat and a building method of the artificial black-necked crane overwintering habitat. The artificial black-necked crane overwintering habitat comprises a night resting site artificially-built region, a natural enemy avoiding site artificially-built region and a foraging site artificially-built region which are located in awater area. The night resting site artificially-built region is located in an artificial island in water. The foraging site artificially-built region is located on the water bank and is close to the night resting site artificially built region. The natural enemy avoiding site artificially-built region is located in a water bay and located between the night resting site artificially-built region and the foraging site artificially-built region. The water area can be a flood plain, a wide shallow river and a reservoir. The artificial black-necked crane overwintering habitat provides an artificially built natural habitat system suitable for the black-necked cranes to live through the whole overwintering period and provides a good living and multiplying site for the rare bird, black-necked crane, and other birds and provides more broad space for smooth overwintering of the black-necked cranes. Besides, the artificial black-necked crane overwintering habitat is simple in structure, low in building cost and beneficial for improvement of the ecological environment.

Description

technical field [0001] The invention relates to the technical field of ecological environment engineering, in particular to an artificial habitat for black-necked cranes overwintering and a construction method thereof. Background technique [0002] The black-necked crane is the most precious bird among many nationally protected birds in Caohai. It is one of the 15 species of cranes in the world and is known as the "bird panda". According to expert data, the black-necked crane is the latest to be discovered by humans and is also the only rare crane bird that lives in the plateau. At present, there are only more than 4,000 black-necked cranes in the world. Black-necked cranes are omnivores and feed on potatoes, corn, wheat, insects, small fish and shrimp, etc. The black-necked crane belongs to the crane-shaped crane family, and is a large bird with a height of about 1.5m when the head is lifted up. The weight of an adult black-necked crane reaches 5kg-6kg. The neck and tail a...
