矿区土壤CO2排放特征及驱动机制研究进展
Research progress on soil CO2 emission characteristics and driving mechanisms in mining areas
摘要
Abstract
Soil respiration is a critical process of the carbon cycle in mining areas.A scientific and ac-curate assessment of its characteristics is essential for understanding regional carbon emission mecha-nisms and for informing strategies that balance resource development with ecological protection.This study reviews existing studies on soil CO2 emissions in mining areas via CiteSpace to analyze research hotspots and evolutionary trends on this topic.We summarized the characteristics and driving mecha-nisms of soil CO2 emissions in mining areas,and discussed existing gaps and future opportunities.Re-sults show that:① Research in this field has evolved through an initial stage(1999-2010)and a rap-id growth stage(2011-present),primarily relying on in-situ monitoring.Studies are concentrated in coal and metal mining areas,focusing on ecosystems such as reclaimed forests,grasslands,and farm-land.② The carbon cycle in mining areas,influenced by coal extraction and reclamation,is highly complex,as is reflected in the dynamic changes between carbon emissions and storage in the ecosystem of mining area at different stages.③ Existing studies have mostly relied on regression analysis to identi-fy influencing factors,but they generally focus on the effect of soil organic carbon on emissions while o-verlooking the contribution of inorganic carbon;moreover,they fail to distinguish CO2 derived from or-ganic versus inorganic sources.Future research should therefore concentrate on exploring deep-soil car-bon dynamics and their driving mechanisms,and on developing localized soil carbon emission models tailored to arid and semi-arid mining areas.关键词
