Embodiment 1

[0017] Embodiment 1 Amphibians cross the ecological module of the ditch

[0018] Such as figure 1 As shown, the ecological module for amphibians to cross the ditch includes: ditch body passage 1, ditch bottom climbing board 3, reflective heat insulation board 7, bracket 6, guide guard plate 5; There are fixing devices, which are fixed on both sides of the ditch; guide guards 5 are provided on both sides of the ditch body channel 1, and the side of the ditch body channel 1 in the direction of ditch water flow is provided with a ditch bottom climbing plate 3, which passes through the shaft 8 and the guide guard 5 Splicing; the reflective heat shield 7 is fixed on the ditch channel 1 through the bracket 6;

[0019] The climbing plate 3 at the bottom of the canal is provided with densely covered holes with a diameter of 20 mm, made of 304 stainless steel, which falls into the side of the canal bottom in the direction of the water flow in an inverted trapezoidal shape, to guide th...

Embodiment 2

[0022] Embodiment 2 The ecological module of amphibians crossing the ditch

[0023] See figure 1 figure 2 , an ecological module for amphibians to cross the ditch, which includes: ditch channel 1, ditch bottom climbing board 3, reflective heat insulation board 7, bracket 6, guide guard 5; the front and rear ends of the ditch channel 1 are provided with fixed The device is fixed on both sides of the ditch; the two sides of the ditch body channel 1 are provided with guide guards 5, and the side of the ditch body channel 1 in the ditch water outflow direction is provided with a ditch bottom climbing plate 3, which is hinged with the guide guard 5 through the shaft 8 ; The reflective heat insulation board 7 is fixed on the ditch channel 1 through the bracket 6;

[0024] Climbing board 3 at the bottom of the canal is provided with densely covered holes with a diameter of 20 mm. The material is 304 stainless steel and is in an inverted trapezoidal shape. After the bottom, the an...

Embodiment 3

[0033] Embodiment 3 layout method

[0034] The steps of the layout method are as follows: First, determine the layout of the canal section, determine the relatively fixed migration route of amphibians and the canal section that is prone to death. The ditches that appear on the relatively fixed migration routes of amphibians need to pay special attention to their lethal and isolation effects on amphibians. For the reconstruction and expansion of ditches, the monitoring of the canal sections with higher lethality of amphibians should be monitored for at least one year. The large-scale migration of amphibians generally chooses a specific time in spring and autumn, and the best layout location should be determined based on the living habits and migration time of the main species. Focus on the ditches where there are micro-ponds nearby, and place under the forest with shade is the first choice. Among the deadly amphibian species, it is judged according to the protection level. The...

Abstract

The invention discloses an amphibians crossing channel ecological module which comprises a channel body passage, a channel bottom climbing plate, a light reflection and heat insulation plate, a support and a guide protection plate. The front end and the back end of the channel body passage are provided with fixing devices and are arranged on the two sides of a channel; the channel body passage is in a slot shape, and a water absorbing material is contained in the slot and is made of cotton, fiber, silk floss, felt and / or hay; the light reflection and heat insulation plate is in a hopper shape, a water storage tank is arranged below the light reflection and heat insulation plate, and the hopper-shaped light reflection and heat insulation plate is used for collecting rainwater and supplanting the water storage tank for water, the water storage tank drips water into the water absorbing material in the slot of the channel body passage through water outlet pipes, and the water absorbing material keeps wet; and soil bases are arranged on the two sides of the channel body passage, a hidden rest place is formed by dead branches placed at the edges and stone riprap, and amphibians are induced to pass through the channel.

Description

technical field [0001] The invention belongs to the field of animal protection, and in particular relates to an ecological module for amphibians to cross ditches. Background technique [0002] Amphibians, which have important ecological research value, have always played an irreplaceable role in the structural integrity and service functions of the ecosystem. system has a significant impact. Most amphibians have the characteristics of seasonal (spring and autumn) migration between wintering grounds, breeding grounds and habitats. Most amphibians complete reproduction in water bodies, and after metamorphosis, larvae forage, migrate and hibernate in moist grasslands and open woodland habitats covered by vegetation and not far from water bodies. For example, in the Changbai Mountain area of ​​Jilin Province, amphibians germinate in spring and leave wintering habitats such as rivers to enter breeding grounds. After breeding, a large number of adults or metamorphic larvae leave...
