A kind of device of aerial vegetation, by wire side on a water-absorbing body, one and once wire side is constituted, and the water-absorbing body coats one plate of presentation by wire side on this and the lower wire side. Furthermore the device of the aerial vegetation penetrates outside the fixed what building of at least four fixing elements, the dust in air is allowed to be able to attachment accumulation on the water-absorbing body as the vegetation of plant growth. Also, vegetable seeds is carried secretly via birds insect or wind propagates to the device of the aerial vegetation, and adhere on the what water-absorbing body. And the water-absorbing body just can provide the nutrient in moisture and vegetation to vegetable seeds in the Hou that drinks up the rain, and grow into plant with sharp plant seed germination, reach low cost purification air and improve the purpose of greenhouse effects.一種空中植被之裝置，其由一吸水體、一上網面及一下網面所構成，而該吸水體由該上網面與該下網面所包覆呈現一板狀。再者，該空中植被之裝置透過至少四固定元件固設於建築物外，讓空氣中的粉塵得以附著累積在該吸水體上作為植物生長的植被。又，植物種子經由鳥類昆蟲夾帶或風吹傳播至該空中植被之裝置，並附著於該吸水體上。而該吸水體在吸收雨水後，便能提供水分與植被中的養分給植物種子，以利植物種子發芽生長成植物，達到低成本淨化空氣及改善溫室效應之目的。
