The invention provides an ecological restoration method for degenerated carex appendiculata wetland, and belongs to the technical field of ecological restoration methods for the wetland. The method comprises the steps of 1, degeneration degree diagnosis of the carex appendiculata wetland, wherein the degeneration degree of the carex appendiculata wetland is determined according to the comprehensive dominance index of dominant species, and the comprehensive dominance index reflects the position and role of the species in a community; 2, restoration of the slightly-degenerated carex appendiculata wetland; 3, restoration of the moderately-degenerated carex appendiculata wetland; 4, restoration of the heavily-degenerated carex appendiculata wetland, wherein moisture regulation and control andplant transplanting are combined, firstly, irrigation is conducted, irrigation is conducted in the last ten days of May, the water level of the earth surface is controlled to be 5-10 cm, then plant transplanting is conducted in August, carex appendiculata is selected as plants, a hole planting mode is adopted with the cluster as the unit, every 30-50 plants serve as one cluster, and the line spacing is 50-100 cm; irrigation is conducted in the middle and lower ten days of May in the next year, and the water level of the earth surface is controlled to be 10-15 cm; 5, maintenance and managementin the later period, wherein irrigation is mainly conducted, the water level of the earth surface is controlled, and moisture regulation and control is conducted.
