摘要
通过研究淮南煤矿塌陷区土地利用/覆盖方式概况及其对区域碳循环的影响,结果表明:淮南为高潜水位地区,煤矿塌陷后,矿区地表形态遭到破坏,煤矿附近的村庄、农田等渐渐被水淹没,形成永久性积水或季节性积水,其生态系统中的动植物、微生物等也受到影响;土地利用/覆盖方式的变化不仅可以直接影响碳循环,而且会引起生态系统的结构和功能改变,尤其是氮循环、水循环、碳浓度、温度等因素的改变,从而间接影响了煤矿塌陷区的碳循环。该研究为淮南煤矿塌陷区生态修复提供了理论依据。
Through studying the overview of land use/cover changes in the Huainan coal mine subsidence area and its effects on the regional carbon cycle, the results show that Huainan is high water table area, form permanent ponding or seasonal ponding was due to land form was destrayed after the subsidence of coal mine, the change of the land use/cover way was not only can directly affect the carbon cycle, but also cause the change of the structure and function in the ecosystem, especially the change of nitrogen cycle, water cycle, carbon concentration, temperature and other factors, so as to affect the carbon cycle of the coal mine subsidence district. The study provides a theoretical basis for the ecological restoration of the Huainan coal mine subsidence area.
