摘要
这项为期3年的中尺度温室研究使用55加仑柱来评估北方旱地和湿地群落在浓密尾砂(0 cm、10 cm和30 cm)上的生存和生长情况。虽然所有处理的存活率都很高，但与未封顶处理相比，PMM封顶处理在整体植物生长、覆盖度和地上生物量方面都有显著改善，其中30 cm PMM封顶的表现优于10 cm PMM。两个群落间的植物生长响应相似，在封顶条件下生长和生存表现最好的树种为山茱萸(Cornus sericea)、白杨树(Populus tremuloides)、黄柳(Salix bebbiana)和小菖蒲(Scirpus microcarpus)。
Growth and survival of native upland and wetland species in shallow capped thickened tailings: A meso-scale greenhouse study
This three-year meso-scale greenhouse study used 55-gallon columns to evaluate the survival and growth of boreal upland and wetland communities on thickened tailings (TT) with 0 cm, 10 cm, and 30 cm peat-mineral mix (PMM) reclamation cap. While survival was high in all treatments, the PMM cap treatments showed significant improvement in overall plant growth, cover, and above-ground biomass compared to the uncapped treatment, with the 30 cm PMM cap outperforming the 10 cm PMM. The plant growth response was similar between the two communities and the top performing species, in terms of survival and growth, in capped TT were Cornus sericea,Populus tremuloides, Salix bebbiana, and Scirpus microcarpus.
期刊介绍：
The Canadian Journal of Soil Science is an international peer-reviewed journal published in cooperation with the Canadian Society of Soil Science. The journal publishes original research on the use, management, structure and development of soils and draws from the disciplines of soil science, agrometeorology, ecology, agricultural engineering, environmental science, hydrology, forestry, geology, geography and climatology. Research is published in a number of topic sections including: agrometeorology; ecology, biological processes and plant interactions; composition and chemical processes; physical processes and interfaces; genesis, landscape processes and relationships; contamination and environmental stewardship; and management for agricultural, forestry and urban uses.
