The invention discloses a lake wetland microtopography construction method based on the response relation of overwintering waterfowls to water levels, which comprises the following steps: fitting a response relation curve of the number of overwintering waterfowls to the water levels, and taking the water level corresponding to the highest point of the response relation curve as the suitable water level of the waterfowls; obtaining wetland type data of the target lake under the scheduling water level and the water bird suitable water level, and respectively recording the wetland type data as first wetland type data and second wetland type data; taking the reduced mud spread and herbaceous marsh area of the first wetland type data relative to the second wetland type data as a restoration area; the area with the elevation lower than the suitable water level of the waterfowl in the restoration area is divided into a submerged area, and the area with the elevation between the suitable water level of the waterfowl
