摘要

Re-establishment of self-sustaining ecosystems is a major challenge in the reclamation of disturbed land from oil sands mining operations. We developed an aggregation technique that was able to create soil-like materials for plant growth using by-products from Alberta oil sands operation process. A research site on Mildred Lake of the Syncrude Canada Ltd., Alberta, Canada was established to assess plant performance on the soil-like material created with this technique. The site was established using composite tailings (CT) as a sub-material. Four different materials were placed on the top of CT (20 cm). Three of the materials are the 1:1 mixture of mature fine tailing (MFT) with CT, amended by 5%, 10% and 15% of peat moss, respectively. These mixtures were produced through a soil aggregation technology developed by Alberta Research Council Inc., Canada. The land reclamation material was used as control. Jack pine (Pinus banksiana, Lamb.), white spruce (Picea glauca Moench Voss), trembling aspen (Populus tremuloides Michx.), hybrid poplar (Northwest), dogwood (Cornus stolonifera Michx.) and American green alder (Alnns crispa [Ait.] Pursh) were planted in 1997. Soil electrical conductivity and soluble salts were monitored along with other physical, chemical and biological properties. Trembling aspen and hybrid poplar outperformed other species. The growth rate for all of species increased with increasing amount of peat moss amendment added in the materials. A significant downward salt movement was observed between the fall of 1998 and the spring of 1999. This may have contributed to the better plant performance during 1999. It is possible to use the oil sand processing by-products to reclaim the disturbed land, however, the challenge is to control soluble salts in rooting zone.
