Drought region lakeside wetland drying and wetting alternation ecosystem restoration system

Abstract

The invention discloses a drought region lakeside wetland drying and wetting alternation ecosystem restoration system, which comprises a bio-cord restoration region, a bio-cord, a first water inlet water pump, a lakeside wetland restoration region, a lakeside isolation zone, a backflow water pump and a second water inlet water pump, wherein the bio-cord restoration region is provided with a first water inlet and a first water outlet; the bio-cord is arranged in the bio-cord restoration region; the lakeside wetland restoration region is provided with a second water inlet, a second water outlet and a backflow opening; a backflow gate is arranged at the backflow opening part; the lakeside isolation zone is communicated with the bio-cord restoration region; a water inlet and a water outlet of the backflow water pump are communicated with the lakeside isolation zone through a water conveying pipeline; the second water inlet water pump is used for conveying water in the lakeside isolation zone into the bio-cord restoration region. The drought region lakeside wetland drying and wetting alternation ecosystem restoration system has the advantages that the problem of poor retainability of water bodies of the drought region lakeside wetland can be effectively solved, and contaminants in lake water can be effectively removed.

Description

technical field [0001] The invention relates to a dry-wet alternate ecological restoration system for lakeside wetlands in arid regions. Background technique [0002] The lakeside wetlands have the natural function of filtering and purifying pollutants (such as nitrogen, phosphorus, organic matter, heavy metal elements, etc.) in the water body. Therefore, it is of great significance to protect lakeside wetlands and construct artificial wetlands around lakes. However, people have insufficient understanding of the vulnerability of lakeside wetlands, and large-scale reclamation of lakes and destruction of vegetation have caused the water quality of lakes to continue to decline, and the surrounding lakeside wetland ecosystems have also been greatly damaged. However, in the inland arid areas of my country, the precipitation is low, the water level of lakes varies greatly from year to year, and the ecosystem is more fragile than that in humid areas. Due to the arid climate and h...
