| 摘 要： | 利用搭建的一套激光击穿光谱测量土壤样品的实验系统，对三峡坝区香溪河段八字门滑坡滑带土壤进行了探测研究。在同一纬度不同海拔高度选取了5个地点采取了土壤样品，对5个样品进行了实验测量，得到了这些土壤样品的光谱图,并对其中的Mg，Al，Si，K等元素进行了定性和定量分析。结果表明，这些元素随着海拔的降低，其含量也逐渐降低。

| Abstract: | An experimental device with laser-induced breakdown spectroscopy(LIBS) for detecting the soil samples was built. The soil samples were researched by the device. According to the same latitude and different height, five locations in Bazimen landslide near Three Gorges Dam were selected to sample. The LIBS spectra of the five samples were obtained. The qualitative and quantitative analyses of Mg, Si, K, Al were performed. The result show that the content of these-elements decreased with the declining height. |
