摘要
探讨了1990~2020年白云鄂博矿的土地利用类型变化,基于InVEST模型定量估算了白云鄂博矿的碳储量改变,并分析了时空变化特征,同时利用生命周期评价,计算出1990~2020年间因采矿所产生的碳排放量.结果表明:1990~2020年,白云鄂博矿碳储存功能受到了破坏性影响,少固碳92万t;1990~2020年间开采铁矿石约3亿t,产生碳排放量约4000万t.
The changes in land use types of Bayan Obo mine from 1990 to 2020 were discussed.Based on the InVEST model,the carbon storage change of Bayan Obo mine was quantitatively estimated,and the spatio-temporal variation characteristics were analyzed.Meanwhile,the carbon emissions caused by mining during 1990-2020 were calculated by life cycle assessment.The results showed that from 1990 to 2020,the carbon storage function of Bayan Obo mine was affected by the destructive effect,and the carbon sequestration was reduced by 920,000 tons;Between 1990 and 2020,about 300 million tons of iron ore were mined,producing about 40 million tons of carbon emissions.
