Castor fiber-protecting bionic channel built near barrage

Abstract

The invention discloses a castor fiber-protecting bionic channel built near a barrage. The bionic channel comprises the barrage built on a river channel according to surrounding topographic lines, anda castor fiber-protecting bionic channel body built by selecting proper surrounding topographic lines for protecting castor fibers, wherein dead wood blocking sills and a gate for adjusting water level and flow are built in the bionic channel body, and salix psammophila is artificially planted at an inlet and outlet and the two sides of the bionic channel body; a water supplementing pool for supplementing water to the bionic channel body is built by selecting proper surrounding topographic lines, the water supplementing pool controls a water supply pipe to supplement water to an adjusting pool through a valve, and the adjusting pool supplements water to the bionic channel body through the gate; and meanwhile, the water supplementing pool irrigates the artificially-planted salix psammophila, and the water supplementing pool adopts a water pump and a water inlet pipe to pump reservoir water for water supplementing. The channel is simple in type, a castor fiber habitat is created, protection of the first-grade state protection animal, namely, the castor fibers, is facilitated, communication and propagation of castor fiber populations blocked by dam construction are facilitated, and the optimization and improvement of race is facilitated.

Description

technical field [0001] The invention discloses a bionic channel for protecting beavers, in particular to a bionic channel for protecting beavers built near a barrage. Background technique [0002] Beaver (scientific name: Castor fiber), is an animal of the Beaver family and the genus Beaver. The beaver has a large body, no obvious difference between male and female, short blunt head, small eyes, short neck, short and wide limbs, short forelimbs, small feet with strong claws, thick and powerful hind limbs, and a large and flat tail. Beavers are nocturnal, rarely come out of their holes during the day, are good at swimming and diving, do not hibernate, are weak in self-defense, are timid, and like to eat twigs, bark, and roots of various plants. -6 Aberdeen, inhabiting the banks of cold temperate and subarctic forests and rivers, mainly distributed in Europe, with a small number in other regions. The beaver has been included in the 2008 Red List of Endangered Species by the ...

Problems solved by technology

[0006] However, due to the construction of water conservancy facilities, the migration route of beavers has been artificially blocked, resulting in a decrease in the number of beavers
