A green energy planting-cultivating compound system includes a roof system, a filter-drain system, a planting-cultivating system, and a support system. The roof system is provided with roof plates positioned on the support system, and each roof plate has a plurality of upper ridge portions and lower groove portions alternately connected, with a layer of water-proof membrane coated on the surface of each roof plate made of both flexible polyolefine and ethylene copolymer bitumen. So the roof plate has an advantage of water proof and resistance against UV, preventing it from corrosion by moist and rusting quickly. Further, a sealing element closes up two ends of each groove of the roof plate so that the groove may store water and soil for cultivating plants and vegetables.The filter-drain system is provided with plural filtering elements positioned on the roof plates, and water level members properly separated in each groove of the roof plate, letting filtered water to overflow them so that miscellaneous substance removed by the filtering elements contained in the filtered water may flow out along a guide pipe in an S route or an drain pipe.The planting-cultivating system is provided with plural soil plates with many holes positioned in each groove of the roof plate, with water flowing just under the soil plates and soil put thereon. And root holders of needed numbers may be inserted in the holes of each soil plate to enable roots of plants and vegetables to catch hold of to grow stably.The support system for supporting the roof system, the filter-drain system and the planning-cultivating system is provided with steel beams and steel frames, fire-resistant accommodations or sound absorbing devices fixed on the steel beamsIn this way, this green energy planting-cultivating compound system can be built on the roof of a building, forming the area for planting and cultivating plants and vegetables for daily life and creating a kind of green environment.本發明為綠能植栽複合結構系統,至少包含
