This creation is that cultivation structure is planted on a kind of related iron sheet roof of what, it is that iron sheet roof is equipped with waterproof layer, and group sets water-bearing layer on what waterproof layer, what water-bearing layer, which is equipped with to plant, again plants layer, thereby, via the layer-by-layer adjusting for planting layer and water-bearing layer cooling is planted, that is, it can reach the effect that the radiant heat energy that sunlight irradiates on what iron sheet roof is effectively inhibited and completely cut off. 本創作係有關於一種鐵皮屋頂植栽結構，係於鐵皮屋頂上設有防水層，並於防水層上組設含水層，又於含水層上設有植栽層，藉此，經由植栽層及含水層的逐層調節降溫，即可達到將陽光照射於鐵皮屋頂上的輻射熱能有效抑制及隔絕的效果。
