| 摘 要： | 为探求快速、廉价、无损、同步的光谱技术在南极古湖沼研究中的可能性,本文分析了南极中山站附近采集的一根湖泊沉积柱样晶的近红外反射光谱数据,通过主成分(PCA)统计分析方法,发现主成分因子载荷值与反映湖泊生产力变化的环境指标S2(有机质热解烃类化合物指标,指示湖藻类来源有机质)在深度剖面上具有一致的变化趋势,两者表现出显著...

| Abstract: | Compared with traditional chemical analysis methods,reflectance spectroscopy has the advantages of speed,minimal or no sample preparation,non-destruction,and low cost.In order to explore the potential application of spectroscopy technology in the paleolimnological study on Antarctic lakes,we took a lake sediment core in Mochou Lake at Zhongshan Station of Antarctic,and analyzed the near infrared reflectance spectroscopy(NIRS) data in the sedimentary samples.The results showed that the factor loadings of pri... |
