A method for setting up a highway amphibian channel system

Abstract

The invention relates to a method for setting a highway amphibian passage system. The method includes determining position of the highway amphibian passage system, setting amphibian migration inducing habitat like a micro pool group and a migration corridor, setting amphibian migration corridor protection facilities like C-shaped structures, structures easy for amphibians to go in an out and warning signs, and evaluating effect of the amphibian passage system. By the highway amphibian passage system, comprehensive functions of realizing water diversion and allowing the amphibians to go through can be realized at the same time and do not interfere each other, and needs for passing through of part of reptiles and small-medium-sized mammals can be met. The method can be used for optimizing the highway amphibian passage system of reconstructed and extended highways and can be used for guiding setting of the highway amphibian passage system of new highways.

Description

technical field [0001] The invention relates to an amphibian channel in the field of animal protection, in particular to a setting method for a road amphibian channel system capable of draining water and facilitating the passage of amphibians Background technique [0002] Most amphibians have the characteristics of seasonal migration between wintering grounds, breeding grounds and habitats. For example, in the Changbai Mountains in Northeast China, amphibians germinate in spring and leave rivers or wintering grounds to enter breeding grounds. The breeding and spawning grounds mostly choose open and sunny pond habitats by the roadside or ponds in the woodland near the road. Adults or metamorphic larvae will leave the pond and enter the terrestrial habitat in the woodland; in autumn, amphibians return to the wintering ground from the terrestrial habitat in the woodland. There are two intensive migration processes in spring and autumn in the whole process. [0003] The impact...

AI Technical Summary

Problems solved by technology

Traditional highway construction has buried many small and medium-sized water bodies due to construction operations such as roadbed construction and road area borrowing and spoiling, and most of these water bodies are breeding grounds for amphibians, so it needs to be recreated and improved when setting highway amphibian passages; in addition During the construction period, oil spills and dust diffusion of mechanical equipment will also cause varying degrees of pollution to nearby water bodies, which is not conducive to the survival of amphibians.

[0004] The second is to destroy the land - living places

The current culverts or the lower part of the bridge and its surroundings are often disturbed by road construction, often with low ground vegetation coverage and dry and barren soil, which makes it difficult for amphibians to approach and use them. It is necessary to improve the habitat of amphibians in the road area when designing road animal passages. Quality, design induction / concealment facilities, try to make the habitat near road culverts and bridges "livable", try to restore the original habitat of amphibians before road construction

[0005] The third is to destroy the migration corridor

[0008] In view of the fact that the above-mentioned existing drainage culverts do not quite match the needs of the bridge setting and the passage of amphibians, after continuous research, it is hoped to create a setting method for the highway amphibian passage system, which can guide the transformation of existing bridges / culverts Or it can be applied in new bridges / culverts on highways to make it more environmentally friendly and practical
