The invention provides a roof greening system, comprising: a roof planting module, including planting soil and vegetation units; a partition buffer module, including a pebble tank with pebbles, a soil retaining unit and a filter layer, which are separated on the roof through the partition buffer module There are multiple roof planting modules, and there are partition buffer modules between two adjacent pieces. The pebble trough has soil retaining units on both sides of the roof slope direction, and the side of the soil retaining unit close to the roof planting modules has a filter layer; drainage blind pipes, Drainage gutters and drainage devices, the drainage blind pipe is set under the planting soil between the partition buffer module and the drainage gutter, the drainage blind pipe runs through the filter layer and the soil retaining unit, and communicates with the pebble groove, and the water on the roof passes through the pebble groove and The drainage blind pipe flows into the drainage gutter and is discharged through the drainage device. The invention divides the roof into multiple roof planting modules through the partition buffer module, so that the slope finding length of each roof planting module is reduced, and the soil quality distribution and soil moisture unevenness caused by rainwater gravity erosion are reduced.

The invention discloses a multifunctional system for rainwater infiltration, collection and storage and purification of a sponge city.The system comprises a bioretention pond and water storage wells.Firstly, appropriate positions are selected for digging of a foundation pit of the bioretention pond and the water storage wells, and the portions, 5-10 cm away from the two sides of the bioretention pond, of the road surface are paved with opened vertical curb belts.The bioretention pond sequentially comprises a gravel covering layer, a vegetation planting soil layer, a biochar packing layer and a gravel drainage layer from top to bottom, and the periphery and bottom of the bioretention pond are both paved with anti-seepage thin film.An overflow pipe is laid on the gravel drainage layer, an upper end overflow opening is 5-10 cm higher than the gravel covering layer, and the lower end of the overflow pipe is connected with a municipal drainage pipe network.The system can be used at the places such as residential areas, schools, parking lots, parks and roads, not only can rainwater be stored, but also the content of pollutants such as nitrogen, phosphorus and heavy metal can be reduced, the purpose of recycling is achieved, city water logging is effectively relieved, and the rainwater use efficiency is improved.
