采矿活动对地质碳汇的影响——以铅锌矿开采为例

Human Effect on Geological Carbon Sink Effect——in Lead-zinc Mining as an Example

全球气候变暖,温室气体CO2的排放在不断增加。尽管整个碳循环过程中地质作用对减少大气中CO2浓度起到重要作用,但人为改造等活动改变了河流水环境化学,并使得原有的地质碳汇减少。结果表明,由于人类对矿产的开采,地质碳汇明显地减少,地质碳汇量减少到约为原来1/2。

The global climate warming, greenhouse gas emissions are increasing in CO2 Although the carbon cycle process of geological action to reduce the concentration of atmospheric CO2 play an important role, but the artificial innovation activities such as change of river water environmental chemistry and makes the original geological carbon reduction, the results show that human on the mining, geological sequestration reduced significantly, geological carbon sequestration is reduced to about half the original.
