Mat for water-level-fluctuating zone and ecological environment improvement method for water-level-fluctuating zone

Abstract

The application discloses a mat for a water-level-fluctuating zone and an ecological environment improvement method for the water-level-fluctuating zone. The mat comprises a mat body, wherein the matbody is divided into a fixed area and a floating area; the mat body comprises a plurality of geogrids; the geogrid located at the fixed area is filled with a first filling material; the geogrid located at the floating area is filled with a second filling material; a vegetation mat is mounted at an upper portion of the geogrid located at the fixed area; an ecological bag or an ecological rod is further mounted in the geogrid located at the floating area; and the ecological bag or the ecological rod is used for planting aquatic plants or transplanting water-resistant woody plants. The mat body is divided into the fixed area and the floating area, and the portion, located in floating area, of the mat body can move and can float automatically with different water levels; by arranging the mat body, side slopes of the water-level-fluctuating zones of lakes and reservoirs can be protected effectively, wave removal and wave resistance are achieved and erosion is reduced; and the mat not only can adsorb nutrient substances and purify water, but also can create a good ecological landscape effect.

Description

technical field [0001] The invention relates to the field of restoration of the ablation zone, in particular to a cutting mat used for the ablation zone and an ecological environment treatment method for the ablation zone. Background technique [0002] The ebb and flow zone refers to a special area where the water level fluctuates seasonally and the surrounding submerged land periodically emerges from the water surface. It is the transition zone controlled alternately by the aquatic ecosystem and the terrestrial ecosystem. Affected by water erosion and wave erosion for a long time, not only the natural vegetation has been stripped away, but also the soil has been emptied, and the rocks have been exposed, forming a rock-fluctuation zone. The site conditions of the rocky water-fluctuation zone are particularly poor, and it is difficult for grass to grow, and the ecological conditions are very harsh. Year after year, it is suppressed by the two extreme environments of flooding ...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the inland lake and reservoir water-fluctuating zones are dominated by natural exposure, which greatly affects the coordination of ecology and landscape. A few gentle slopes are dominated by natural restoration of aquatic plants, which is difficult to last
