异龙湖表层沉积物有机质的分布特征与来源研究

Study on Distribution Characteristics and Sources of Organic Matter in Surface Sediments of Yilong Lake

异龙湖为云南省九大高原湖泊之一,但淤积严重,研究表层沉积物有机质含量有助于了解湖泊生态系统健康状况。在异龙湖设置12个采样点,测定表层沉积物的有机质含量,讨论其空间分布及成因。结果显示,异龙湖东部区域有机质含量较高,这与区域水动力学变化、人类活动及陆源输入有关。溯源分析可为防控内源污染和制定湖泊管理策略提供基础数据。

Yilong lake is one of the nine plateau lakes in Yunnan province,but it is severely silted up,studying the organic matter content of surface sediments can help understand the health status of the lake ecosystem.12 sampling points are set up in Yilong lake to measure the organic matter content of surface sediments,and discuss their spatial distribution and genesis.The results show that the organic matter content in the eastern region of Yilong lake is relatively high,which is related to regional hydrodynamic changes,human activities,and terrestrial inputs.Traceability analysis can provide basic data for preventing and controlling endogenous pollution and formulating lake management strategies.
