The building garbage stacking and burying not only greatly encroaches on the land, but also pollutes water, atmosphere and soil, and seriously influences the city appearance and the environmental sanitation. In addition, the secondary pollution to the urban air caused by the scattering of the residue soil and the flying of the dust and the sand ash in the clearing and stacking processes directly or indirectly influences the air quality.
