Problems solved by technology

[0002] Removing algae and controlling its growth are difficult problems in the restoration and protection of lakes and reservoirs. At present, there are three main types of technologies used in the world: ①Chemical methods: such as adding chemical agents to kill algae, adding iron salts to promote phosphorus precipitation, adding lime to denitrify, etc. , but it is easy to cause secondary pollution; ②Physical methods: dredging sediment, mechanical algae removal, diverting water to wash away silt, etc., but the symptoms are not cured; ③Ecological-biological methods: It is a new technology that has developed rapidly abroad in recent years. Water ecology - bioremediation technology is to restore the original appearance of nature according to the laws of nature itself, and strengthen the self-purification ability of nature to treat polluted water bodies. This is a logical pollution control idea for the harmonious coexistence of man and nature, and it is also an innovative technology. route
This method relies on natural recovery, and is not suitable for implementation in lakeshore areas with strong wind and waves and severe ecological damage.

Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with accompanying drawing 1 .

[0022] According to accompanying drawing 1 as can be known, the method for the restoration of this kind of lakeshore zone is as follows:

[0023] 1. Select a location with a water depth of 80cm or 90cm or 100cm or 110cm inside the 200-mu coastal zone 1 in the test area, and delineate a water area of ​​15 mu;

[0024] 2. Set up the wave-dissipating layer 4. According to the delineated range of 15 mu, drive wooden piles, and the wooden piles are arranged in an S shape;

[0025] 3. Set up the anti-wave layer 3 and the floating anti-wave layer 2. Nail wooden piles at 3-5m inside the wave-dissipating layer 4. The wooden piles are arranged in a line with a distance of 1m. Iron plates are nailed on the wooden piles for Anti-wave, at the same time set the floating anti-wave layer 2 made of foam;

[0026] 4. Choose 1-3 kinds of emergent plants: choose Cattail 7 that i...

Abstract

The character is to delimit scope in deep water area at selected lake shore band at first, then to select plants, the third is to set plants row pitch, the fourth is to set anti-wave layer and fix wood pile, the fifth is to set wave-proof layer which is made by pilling wood pile at internal side of anti-wave player and fitting iron plate on the wood pile and float wave-proof layer which is made by polyfoam, the sixth is to set planting position of emergent aquatic plant and submerged plant, the seventh is maintenance.

Description

technical field [0001] The invention relates to ecological restoration of aquatic vegetation in the lakeshore zone, and more particularly relates to a method for ecological restoration of the lakeshore zone. It is suitable for ecological restoration of places where aquatic vegetation is seriously damaged in the lakeshore zone. Background technique [0002] Removing algae and controlling its growth are difficult problems in the restoration and protection of lakes and reservoirs. At present, there are three main types of technologies used in the world: ①Chemical methods: such as adding chemical agents to kill algae, adding iron salts to promote phosphorus precipitation, adding lime to denitrify, etc. , but it is easy to cause secondary pollution; ②Physical methods: dredging sediment, mechanical algae removal, diverting water to wash away silt, etc., but the symptoms are not cured; ③Ecological-biological methods: It is a new technology that has developed rapidly abroad in recen...
