Embodiment 1

[0043] Such as figure 1 and Figure 2.1 - As shown in 2.3, a Quxi-type constructed wetland system suitable for artificial restoration of aquatic fireflies, including aquatic area 2, terrestrial area 8 and weir 4. The aquatic zone 2 and the terrestrial zone 8 are separated by a water level line, and the bottom of the aquatic zone 2 and the terrestrial zone 8 form a side slope 3 . The slope of the side slope 3 is less than 45°, preferably, the slope of the side slope 3 is less than 20°. The aquatic area 2 is strip-shaped, the water flow direction of the aquatic area 2 is S-shaped, and the aquatic area 2 is provided with a water flow turning area 5 . Aquatic zone 2 includes a wide-flow area 9 with different water surface widths (the water flow velocity in the wide-flow area 9 is relatively slow) and a narrow-flow area 10 (the water flow velocity in the narrow-flow area 10 is relatively fast); the slope 3 includes steep slopes with different gradients Area 6 (water body in aqua...

Embodiment 2

[0054] Such as image 3 and Figure 4 As shown, a ladder pond constructed wetland system suitable for artificially reproducing aquatic fireflies includes an aquatic area 9 and a terrestrial area, and the aquatic area 9 and the terrestrial area are separated by a water level line. The bottom of the aquatic zone 9 and the terrestrial zone form a slope 10 . The slope of the side slope 10 is the best if it is less than 20° with 10-15°. The aquatic area 9 is stepped, and the land area includes the multi-level pond slope earth ridge 4 that is arranged successively along the water flow direction of the aquatic area 9, and the adjacent two-level pond slope earth ridge 4 divides the aquatic area 9 into multi-level ladder ponds 2, ponds The slope soil ridge 4 is provided with a discharge port 8 for water supply to flow from the ladder pond 2 of the upper stage to the ladder pond 2 of the next stage, and the discharge port 8 is provided with a water blocking object for controlling the ...

Embodiment 3

[0068] Such as Figure 5 As shown, a rice field-type constructed wetland system suitable for artificial restoration of aquatic fireflies, including aquatic areas and terrestrial areas, the aquatic areas and terrestrial areas are separated by water level lines; the bottom of the aquatic area and the terrestrial area form a slope . The difference from Embodiment 2 is that the rice field-type constructed wetland system is a relatively extreme state of micro-flow or static water flow in Embodiment 2, and it is applied to slow or static water based on the Gramineae herbaceous Oryza genus. In the main surface-flow wetland habitat, emergent plants are planted in a large area in the aquatic area to create a suitable plant mix for the growth of aquatic fireflies and a habitat with reasonable canopy density, slow flow, shallow water, and gentle bank slope. The water level adjustment structure of the rice field-type constructed wetland system includes an inlet ditch and a drainage ditch...

Abstract

The invention discloses an artificial wetland system suitable for artificial restoration of aquatic fireflies and a construction method. The artificial wetland system comprises an aquatic area and a terrestrial area which are separated by a water line, wherein the water bottom of the aquatic area and the terrestrial area form a side slope with the gradient smaller than 45 degrees; the water body depth of the aquatic area is not larger than 30 cm, and the average water body flow velocity is not higher than 30 cm / s; and a water level adjusting structure used for adjusting the water depth of the aquatic area is arranged in the terrestrial area and / or the aquatic area. According to the invention, a land and water environment required by survival and reproduction of the aquatic fireflies is constructed, the climbing slope design requirement of the aquatic fireflies is given according to the pupation characteristic of the fireflies, and the water depth and flow velocity of an aquatic area are controlled, so that an ecological environment suitable for survival and reproduction of the firefly larvae is created; and particularly, the water depth of the aquatic area can be controlled by arranging the water level adjusting structure, and the requirements of the aquatic fireflies on the water depth in different seasons can be better met.

Description

technical field [0001] The invention relates to the technical field of ecological environmental protection, and is a scheme for the construction of ecological habitats for high-level ecological indicator insects, and a technical method for constructing ecological habitats for firefly insects, especially aquatic fireflies, in artificial wetlands. Rehabilitation of aquatic fireflies in artificially constructed wetland systems under semi-natural conditions. Background technique [0002] In nature, fireflies are in the middle and upper layers of the trophic level of the food chain, that is, predators, and fireflies are one of the indicators of high-quality ecological environments; as "umbrella species" in ecology, they have an umbrella effect. When there are fireflies in an area , indicating that the diversity of ecological species in this area is high, the ecological level is high, and the organisms in the downstream food chain of fireflies and related food webs are relatively ...
