矿区生态破坏碳扰动研究——以徐州九里矿为例

    Research on carbon disturbance of mine ecological damage:A Case Study in Xuzhou Jiuli mine

    • 摘要: 矿区煤炭开采对生态系统碳储量造成极大的干扰。以徐州九里矿区为例,运用遥感手段对矿区1995、2001、2009年各土地利用类型进行提取,集中分析矿区植被碳和土壤有机碳的变化情况。结果发现,1995年至2009年九里矿区土地利用变化明显;2009年矿区植被碳储量为3525吨碳比2001年有所减少;1995年、2001年、2009年土壤有机碳储量以2001年最小为174334.1吨碳, 2009年土壤有机碳储量为182329.1吨碳,比2001年增加了7995吨碳储量。最后得出结论,矿区生态破坏对生态系统碳扰动明显。

       

      Abstract: Coal mining disturbs the carbon storage of mine ecosystem.It takes Xuzhou Jiuli mine for example,using remote sensing tools to extract the mining area of different land use type in 1995,2001,2009.Based on this,it analyzes the changes of vegetation carbon and soil organic carbon.The results show that the changes of land use type in Jiuli mine are obvious from 1995 to 2009.In 2009,the vegetation carbon reserves is 3525 tons less than 2001;In 2001,the soil organic carbon reserves is 175323.6 tons less than 1995 and 2009,and in 2009,the number is 182426.2 tons have an increase of 7103.6 tons compared with 2001.It concludes that mining ecological damage has obvious disturbance on ecosystem carbon storage.
