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.
