摘要
以大庆区域连环湖中的牙门喜泡为研究对象,对采自牙门喜泡24cm柱状沉积岩心进行总氮、有机质指标的测试和分析.分析结果显示,24～2 cm阶段总氮和有机质含量最低,此时人类活动对湖泊沉积的影响微弱.21～10 cm阶段氮和有机质指标较稳定,而10～0 cm阶段氮和有机质波动幅度增大,显示人类活动的影响增强.
Yamenxi Lake of Lianhuan Lake was researched in Daqing city and its sediment core with 24 cm depth was analyzed in the total nitrogen and organic matter.The total nitrogen and organic matter were the lowest in 24~21 cm with the weak human activities.The total nitrogen and organic matte were stable in 21~10 cm,while the total nitrogen and organic matter fluctuated greatly in 10~0 cm,showing the human activities increased.
