　　南海北部陆坡柱状沉积物的常量元素统计分析表明，沉积物中的Ti、Al、Fe、K、Mn、Mg代表了陆源元素组合；而消除粒度效应的陆源元素比值 Al/Ti、Fe/Ti和K/Ti等的变化曲线与浮游有孔虫氧同位素曲线对比表明，在气候变冷事件（Heinrich事件、Younger Dryas事件、PME斜室普林虫低值等事件）期间，陆源常量元素比值明显降低。这一对应特征，一方面体现了气候变冷事件的发生对陆源区化学风化强度的制约，另一方面也说明与指示长时间尺度气候相似，陆源元素比值对短时间尺度的气候变化也具有明显的指示作用。

The statistical results of major elements in the sediments collected from northern slope of the South China Sea indicate that the terrestrial element association are Ti ,Al ,Fe ,K ,Mn ,Mg. The comparison of the Ti normal-ized ratios of the major elements curves (such as Al/Ti、Fe/Ti and K/Ti) and planktonic foraminifera oxygen iso-topic curve are presented that ,during the cooling events (Heinrich event ,Younger Dryas event ,PME event) ,the terrestrial major element ratios decreased significantly. On one side ,these characteristics of major elements show that the cooling events might influence the chemical weathering intensity in terrigenous area ,on the other ,it also plays an obvious indication role in short time scales climate changes ,which is similar to indicating large time scales climate changes .
