Abstract
Baed on the study on the physical and chemical characteristics, three solid wastes, namely ooze, alkaline slag, coal ash, that have been piled up largely in coastal region are converted into a kind of artificial soil and substituted for the foreign soil. It relieves the shortage of planting soil of the landscaping construction in TEDA and also accords with the sustainable development demands for the environmental construction. Experiments and applications show that the most feasible mixing proportion of ooze to alkaline slagor coal ash is 3: 1. Further more, the artificial soil exceeds coastal solonchak in amelioration of soil and plant suitability. Its overall benefit is prominent.
