PROBLEM TO BE SOLVED: To provide a greening mat structure excellent in water permeability and durability. SOLUTION: The greening mat structure has a base layer which is made by curving continuous filament bodies made of polyolefine resin into a three-dimensional random form and fusing at least part of the interlacing part of the continuous filament bodies, and a nonwoven fabric layer made of polyester fiber and on one side or both sides of the base layer. The base layer and the nonwoven fabric layer are stuck to each other with an ethylene-based copolymer and the peel strength of the base layer and the nonwoven fabric layer is 9.8N/5cm or above.
