PROBLEM TO BE SOLVED: To provide a green land structure excellent in cushioning properties during walking when constructing, facilitating rooting when vegetating greening plants such as lawn to make settlement of greening plants sufficient, and capable of being made further lightweight. SOLUTION: This green land structure (B2) comprises arranging on a construction part a drainage member (3) with water permeability for excellently performing drainage, pouring on the drainage member (3), a product which is obtained by mixing 30-70 wt.% of shirasu, 10-30 wt.% of sand and 10-40 wt.% of sodium silicate with≥6 wt.% of alumina cement at an appropriate ratio followed by stirring, solidifying the product at a prescribed thickness, and vegetating greening plants (4) on the surface of the product.
