摘　　要：利用电感耦合等离子体-质谱法（ICP-MS）和傅里叶变换红外光谱（FTIT）对云南省元谋土林风景区7种不同颜色土壤进行分析．ICP-MS测试结果显示，土壤中富含速效磷、钾、钙、镁、铜、铁、锌、锰等多种无机元素，且不同颜色土壤的常量与微量元素含量不同。速效磷、钾、镁、铜、铁、锌、锰含量均与速效钙呈负相关关系．FTIR分析结果表明，7种土壤的红外光谱非常相似，以3698，3621，1032，798，779，694cm^-1峰以及470cm^-1峰是主要的特征吸收峰。7种土壤的红外光谱属于高岭土型图谱，其矿物成分以石英为主，含有少量的磷酸盐、金属氧化物等成分．研究结果表明电感耦合等离子体质谱结合傅里叶变换红外光谱为土林土壤的成分分析研究提供了一种简易可靠的方法．Inductively coupled plasma mass spectrometry （ICP-MS） and Fourier transform infrared spectroscopy （FTIR） were used to study seven different colors of soil in Yuanmou Earth-Forest Scenic Spot in Yunnan. The ICP-MS results showed that available P, K, Ca, Mg, Cu, Fe, Zn and Mn were found in the soil, and the contents .of major and trace elements for different colors of soil were different. A significantly negative correlation is observed between available P, K, Ca, Mg, Cu, Fe, Zn and Mn and available Ca. The FTIR results showed that IR spectra of seven different soil samples were similar. The strong 3698, 3621, 1032, 798, 779, 694 cm^-1 peak and470 cm^-1 peak were the main absorption bands. The infrared spectra of the 7 soils were kaolin type. Quartz was the main component of mineral in seven soils, which contained a small amount of phosphates, metal oxides and other components so on. The results showed that ICP-MS combined with FTIR can provide a simple and reliable method for the component of mineral analysis of soil in Earth-Forest.
