Artificial lake structure with self-purification function and construction method thereof

The invention discloses an artificial lake structure with a self-purification function and a construction method thereof, and relates to the technical field of artificial lake construction. The artificial lake structure comprises a shallow water area, a deep water area and a transition area which are at least divided in a groove-shaped space, and the deep water area is located between the shallow water area and the transition area; and a protection platform is arranged between the shallow water area and the deep water area, an island reef area is arranged between the transition area and the deep water area, and the space between the transition area and the groove wall of the groove-shaped space is filled with gravel. According to the construction method, construction is carried out in sequence according to planned positions of the shallow water area, the deep water area, the island reef area and the transition area. The artificial lake structure is simple in structure and reasonable in design, especially thro
