About 140-year changes in the trace metals in Porites coral samples from two locations in the northern South China Sea were investigated. Results of PCA analyses suggest that near the coast, terrestrial input impacted behavior of trace metals by 28.4%, impact of Sea Surface Temperature (SST) was 19.0%, contribution of war and infrastructure were 14.4% and 15.6% respectively. But for a location in the open sea, contribution of War and SST reached 33.2% and 16.5%, while activities of infrastructure and guano exploration reached 13.2% and 14.7%. While the spatiotemporal change model of Cu, Cd and Pb in seawater of the north area of South China Sea during 1986-1997 were reconstructed. It was found that in the sea area Cu and Cd contaminations were distributed near the coast while areas around Sanya, Hainan had high Pb levels because of the well-developed tourism related activities.
研究了南海北部两个地点的 Porites 珊瑚样本中痕量金属约 140 年来的变化。主成分分析的结果表明，在近岸地区，陆地输入通过 28.4%影响痕量金属的行为，海面温度（SST）的影响为 19.0%，战争和基础设施的贡献分别为 14.4%和 15.6%。但对于开阔海域的一个地点，战争和 SST 的贡献分别达到 33.2%和 16.5%，而基础设施和鸟粪勘探的活动分别达到 13.2%和 14.7%。同时，重建了 1986-1997 年期间南海北部海域海水 Cu、Cd 和 Pb 的时空变化模型。结果表明，在该海域，Cu 和 Cd 污染分布在近岸地区，而海南三亚附近地区由于发达的旅游相关活动，Pb 水平较高。
