【摘要】：研究矿区土壤有机碳的储量、影响因素以及时空变异规律,不仅对认识矿区土壤质量变化规律,而且对排土场覆土工艺和植被类型的选择具有重要的指导意义。植被、土壤质量等自然因素以及复垦管理措施、复垦模式等人为干扰会对矿区土壤有机碳的积累和转化造成重要影响。目前,对于矿区土壤有机碳的变化过程和转化机理的研究不够深入,尤其是土壤有机碳对复垦措施的响应规律鲜见报道。本文系统梳理了国内外学者对矿区土壤样品有机碳含量的测量和区域土壤有机碳储量的估算,自然因素、人为干扰对矿区土壤有机碳积累的影响。在此基础上,提出了深入研究的方向:1加强矿区土壤有机碳剖面结构的变化及其转化机制的研究;2加强对影响土壤有机碳积累的不确定因素的探讨研究;3应加强复垦模式及覆土工艺以及排土场微地形对土壤有机碳积累机理的研究。
[Abstract]:The study of soil organic carbon storage, influencing factors and temporal and spatial variation in mining area is of great significance not only to understand the changing rule of soil quality in mining area, but also to select the technology of overlying soil and the type of vegetation in dump. Natural factors such as soil quality, reclamation management measures, reclamation patterns and other man-made disturbances will have an important impact on the accumulation and transformation of soil organic carbon in mining areas. The study on the process and mechanism of soil organic carbon in mining area is not deep enough. Especially, there are few reports on the response of soil organic carbon to reclamation measures. This paper systematically reviews the measurement of soil organic carbon content and the estimation of regional soil organic carbon reserves by domestic and foreign scholars. Effects of anthropogenic interference on soil organic carbon accumulation in mining areas. This paper puts forward the direction of further study on the change of soil organic carbon profile structure and the transformation mechanism of soil organic carbon in the mining area. 2. The study on the uncertain factors affecting the accumulation of soil organic carbon should be strengthened and the reclamation model and its overlying should be strengthened. Study on the mechanism of soil organic carbon accumulation by soil technology and microtopography of dump.
