Terrace field type ecology landscape lake and construction method thereof

Abstract

The invention discloses a terrace field type ecology landscape lake and a construction method thereof. The bottom of the landscape lake from the center to the bank is in a trend of being gradually risen as a whole, corresponding bottom cofferdams are arranged at a plurality of stages of contour lines at intervals from the center to the bank of the landscape lake, each circle of the bottom cofferdam surrounds the landscape lake for one circle, the landscape lake is divided into a plurality of surrounding lake areas by all bottom cofferdams; sinking water landscape plants are planted at the bottom of the lake. Due to adoption of the stage-shaped bottom cofferdams the bottom of the lake is divided into the plurality of the surrounding lake areas, and together with radial partitioning walls each surrounding lake area is further divided into a plurality of cofferdam blocks. Therefore, in the overall construction process of the landscape lake, sectional soil construction can be implemented,and planting and water injection can be implemented at different times, so that the construction progress is compact, and the construction process is effectively increased. In addition, the sinking plants can be maintained and replaced at an early state at a low primary maintenance water level, so that problems of tedious later plant replenishing and the like after large-scale death of aquatic plants are avoided.

Description

technical field [0001] The invention belongs to the technical field of water ecological engineering, environmental protection engineering and landscape construction, and in particular relates to a terraced ecological landscape lake and a construction method thereof. Background technique [0002] At present, the planting technology of submerged plants in the process of water ecological restoration is bottom-up, using the method of gradually storing water from the lowest water level to plant submerged plants layer by layer. If the entire water area is full of submerged plants, it needs The whole water area is fully filled with water. This method requires a large amount of water, especially in the face of large water bodies, which requires a large amount of water in a short period of time to ensure the survival rate of planted submerged plants. The water source quickly replenishes the required amount of water, and in the traditional planting method, the planting activities of t...

[0002] At present, the planting technology of submerged plants in the process of water ecological restoration is bottom-up, using the method of gradually storing water from the lowest water level to plant submerged plants layer by layer. If the entire water area is full of submerged plants, it needs The whole water area is fully filled with water. This method requires a large amount of water, especially in the face of large water bodies, which requires a large amount of water in a short period of time to ensure the survival rate of planted submerged plants. The water source quickly replenishes the required amount of water, and in the traditional planting method, the planting activities of the workers will continuously stir up the sediment in the water and run through the entire construction process. Due to the diffusion of pollutants in the water, the planting method will affect large areas of water. It causes long-term water turbidity, the water cannot be static and settles, which affects the photosynthesis of the whole submerged plants, seriously damages the strong positive submerged plants, and even dies in large numbers, which makes the whole project cost half the effort and manpower and material resources.
