Folding ecological floating island

The invention relates to a folding ecological floating island. The folding ecological floating island comprises a plurality of connecting pieces, a plurality of floating island groups and a plurality of driving pieces I, the multiple connecting pieces are linearly distributed at intervals, and the connecting piece located on the outermost side is fixed to one side of a river bank. One floating island group is arranged between any two adjacent connecting pieces, each floating island group comprises at least two floating bodies which can float on the water surface and are distributed in a straight line, and plants are planted on the floating bodies; and in each floating island group, the end parts of any two adjacent floating bodies are connected in a running fit manner, and the two floating bodies positioned on the outermost side are respectively connected with the corresponding two adjacent connecting pieces in a running fit manner. And one first driving piece is arranged between any two adjacent connecting p
