高潜水位采煤沉陷区有机碳库演替特征研究

Evolution Characteristics of “Organic Carbon”in Coal Mining Subsidence Wetland with High Groundwater Level

根据对徐州九里采煤沉陷区不同地带土壤有机碳密度取样对比分析,沉陷区坡面区有机碳库出现了明显流失,而矿区沉陷积水区域碳汇功能显著,为采煤沉陷区生态修复提供了保护碳汇功能的依据。

According to contrast analysis of organic carbon density samples of soil from different areas in Jiuli coal mining of Xuzhou, the organic carbon pool in subsidence slope area appeared a significant loss, however carbon sinks func- tion is significant in the mining subsidence water area. It provides a basis for protecting the carbon sinks function in ecologi- cal reclamation of coal mining subsidence area.
