A Simulation of Temporal and Spatial Variations in Carbon at Landscape Level: A Case Study for Lake Abitibi Model Forest in Ontario,Canada

Using a case study of the Lake Abitibi Model Forest (LAMF), this study aims to assess the temporal and spatial variability in carbon storage during 1990–2000, and to present a comprehensive estimation of the carbon budget for LAMF's ecosystems. As well, it provided the information needed by local forest managers to develop ecological and carbon-based indicators and monitor the sustainability of forest ecosystems. Temporal and spatial carbon dynamics were simulated at the landscape level using ecosystem model TRIPLEX1.0 and Geographical Information System (GIS). The simulated net primary productivity (NPP) and carbon storage in forest biomass and soil were compared with field data and results from other studies for Canada's boreal forests. The results show that simulated NPP ranged from 3.26 to 3.34 tC ha⁻¹ yr⁻¹ in the 1990s and was consistent with the range measured during the Boreal Ecosystem-Atmosphere Studies (BOREAS) in central Canada. Modeled NPP was also compared with the estimation from remote sensing data. The density of total above-and belowground biomass was 125.3, 111.8, and 106.5 tC ha⁻¹ for black spruce, trembling aspen, and jack pine in the LAMF ecosystem, respectively. The total carbon density of forested land was estimated at 154.4 tC ha⁻¹ with the proportion of 4:6 for total biomass and soil. The analysis of net carbon balance of ecosystem suggested that the LAMF forest ecosystem was acting as a carbon sink with an allowable harvest in the 1990s.     

海洋巨藻生物吸附剂对Hg~(2 )吸附性能的研究

就丰产廉价的海洋巨藻(Durvillaea Potatorum)所制的生物吸附剂对Hg2 的吸附性能进行了研究,该生物吸附剂经特殊的稳定化预处理而得。研究表明,该生物吸附剂的Hg2 吸附容量对溶液的pH值十分敏感,在pH=3时,最大吸附容量达到3.1mmol/g(干重),在溶液pH=0.4～5.0的范围内,Hg2 的吸附容量为0.49—3.1mmol/g(干重);溶液中的C1-能显著地降低生物吸附剂对Hg2 的吸附容量;其对Hg2 的去除率可达到99％以上。该生物吸附剂可以有效地去除工业废水中的Hg2 。
