The invention discloses a vegetation slope protection net made of a nonwoven fabric. The vegetation slope protection net comprises six or eight or more vegetation belts which are determined accordingto the slope surfaces, a tightening rope is arranged between every two adjacent vegetation belts in a spaced mode, and thus the vegetation belts are mutually connected into a whole to form a pluralityof three-dimensional vegetation meshes. The structure is simple, and the vegetation slope protection net made of the nonwoven fabric and provided with the multiple three-dimensional meshes is low incost, good in water retention and soil fixation effect, high in penetrability of plant root systems, convenient to carry and transport, and suitable for being used on slopes beside railways, roads andembankments.
