Description
Technical Field
The invention relates to a bionic channel for protecting a nutria, in particular to a bionic channel for protecting a nutria, which is built near a barrage.
Background
Beaver (known as Castor fiber) is an animal belonging to the genus beaver, the family beaver. The beaver has the advantages of fat body, no obvious difference between female and male, short and blunt head, small eyes, short neck, short and wide limbs, short forelimb, small foot, strong paw, strong and powerful hind limb, and big and flat tail. The beaver moves at night, rarely goes out of the hole in the daytime, swims and dives well, does not sleep in winter, has weak self-defense capability, has small gallbladder, is fond of eating twigs, barks and tree roots of various plants, is bred for 1 time every year, inhabits 1-6 per fetus, inhabits along the bank of forest rivers in cold temperate zone and subarctic zone, is mainly distributed in Europe, and has less quantity in other areas. The beaver is listed in red record of endangered species in the world nature protection alliance (IUCN)2008 and belongs to the first-class protection animal of the state.
The nutria is produced in forest rivers in cold and warm zones and subarctic zones, inhabit on the shore, and broadleaf dense forests, shrubbery forests and river valley areas with smooth and deep water flow are selected as inhabit sites. The beaver moves at night, rarely goes out of the hole in the daytime, swims and dives well, and does not hibernate. One unique feature of the beaver is that the beaver is a dam, and all the places where the beaver inhabits or inhabits are ponds, lakes or marshes. The beaver generally builds a nest near water, a nest room is built by branches and soil, and the height of the ground is 0.8-1.9 m. The dwelling mode of the beaver mainly comprises 3 types of hole dwelling, nest dwelling and hole nest dwelling combination. Holes are both permanent and temporary. In spring flood period every year, because ice and snow melt and river water flood, part of the beaver holes are submerged by flood, so that the beaver is forced to move in short distance, and simple holes are built on the branch channels or the small islands for temporary or refuge. The permanent cave is a place for the river raccoon to live through winter and breed, and the structure is relatively complex. The holes are generally distributed in a higher (more than 1.5m from the ice surface) section of the river bank; the hole-nest combination (i.e. underground with a hole system, and a nest with a civil structure added on the ground) is mostly distributed on a medium river bank with the height of below 1.5m from the ice surface. The simple nest is built in the marsh or on the island of the shallow water land. Many of the cave systems and the cave nests are in river bend sections with gentle water flow, the water depth is generally more than 2m, and the river width is about 15 m. Castors usually build 2-8 temporary caves near the nest for emergency refuge and temporary rest.
The beaver likes to eat the tender branches, barks and roots of various plants, but also eats the aquatic plants, the tender branches, leaves and barks of the poplar and the willow. In summer, the beaver also eats herbaceous plants such as rhizoma Acori Calami, rhizoma Sparganii, herba Alii Fistulosi and Gramineae. In autumn, when the beaver moves frequently in the morning and evening, the beaver bites off the branches into about 1 meter, and the branches are caught in deep water near the opening of the cave and stored for eating in winter
The river racoon dog is only distributed in water bodies such as the Qinghe, the Boolean root river, the Wulungu river and the like in the northeast of Xinjiang in China, is called an activated stone of an ancient vertebrate, and has higher research value. The population distribution is scattered, the number of the beavers in Asia is very small, and about 700 beavers are obtained in China.
However, the relocation route of the beaver is artificially blocked due to the construction of water conservancy facilities, so that the number of the beaver is reduced. By the establishment of dam hydropower stations, in winter, ice layers are continuously increased due to water storage and power generation, water even submerges nests of some nutria, the nutria needs a dry environment, and the habitat of the nutria is reduced. The number of the abandoned holes exceeds the effective number of the holes, and the castors are difficult to find a proper section to build the nest after continuing. Based on the reasons, the barrage is constructed, a bionic channel for protecting the beaver needs to be constructed, the beaver habitat is built, the protection of the national first-level protected animal beaver is facilitated, and the interchange propagation among beaver populations blocked by the dam is facilitated.
