摘要
对龙河口水库建库以来代表性沉积物柱样(ALE)进行了磁性参数测量和粒度分析,探讨了各磁性参数随深度变化的特点及与粒度参数的关系。同时通过与流域降水量曲线的比较,认为库区沉积物受降水量影响显著,cARM/c可作为反映流域降水量变化的一个间接指标。
Based on the environmental magnetic measurement and partical sizw analyses on the core ALE collected from Longhekou reservoir, it has been analyzed the curve that the environmental magnetic parameters vary alone with the depth and the relationship between magnetic parameters and particle sizw parameters. Compared with the curve of rainfall in the almost 50 years , it can be deduced that CABM/C can be used as indirect pooxies for rainfall.
