    Evolution of Eco-Environment and Carbon Burial of Critical Zones in Xiantao Area, Hubei Province

    • 摘要: 仙桃地区湖群不断萎缩,水体富营养化水平和湿地沉积物重金属含量持续升高,江汉湖群生态系统日益脆弱,加强对该地区生态环境演化研究、分析人类活动和富营养化对湖泊生态系统的影响、探究该地区不同沉积环境的碳埋藏规律等显得尤为重要.在对江汉平原重点地区(仙桃彭场镇幅和脉旺咀幅)第四纪地质调查的基础上,选取研究区大型渔场、小型鱼塘、沟滩、湖泊、水稻田、泄洪道、旱地、汉水阶地8种不同沉积环境的16个关键带点位,分别测定了其表层及浅层钻孔沉积物的色素、TOC(total organic carbon,总有机碳)与TN(total nitrogen,总氮).表层沉积物TOC含量反映了研究区南部多湖泊区域有机碳埋藏量较高,而北部冲、洪积成因环境相对较低,与色素、TN所指示的人类活动强度和富营养化水平相吻合.湿地浅层钻孔沉积物碳埋藏速率变化整体表现为升高趋势,与色素所指示的湖泊富营养化的趋势相吻合;不同沉积环境碳埋藏速率差异较大,最高为大型渔场77.71 g·m-2·a-1、最低为汉水阶地3.61 g·m-2·a-1.研究结果表明,受到人类活动影响,湖相沉积物中碳埋藏量相对较高,湖泊碳汇功能不断增强,这对江汉平原关键带碳循环研究具有重要意义.
