| 摘 要： | 以长江三峡岩溶地区仙女山隧洞内一根生长期为9年的现代石笋为研究对象,利用数字图像分析技术获得高分辨率的年际-季节时间尺度的石笋灰度序列。与当地器测气象数据进行对比分析发现,仙女山石笋灰度和降水量、温度具有相似的变化趋势:降水量越大,温度越高,石笋灰度值越大;降水量越小,温度越低,石笋灰度值越小。关于影响石笋灰度变化的主导因素是降水量还是温度,还需要进一步深入的研究。

| Abstract: | A 9-year contemporary stalagmite got from an artificial tunnel inside the Fairy Hill in the Three Gorges area is used as the research object, and high-resolution stalagmite gray level series on interannualseasonal time scale are obtained by means of digital image analysis in the study. In comparison with the local monitoring meteorological data, it is found that the grayscale of the contemporary stalagmite is of similar variation tendency with the monitoring precipitation and temperature data. That is to say, the greater the precipitation and the higher the temperature are, the bigger the grayscale of the contemporary stalagmite and vice versa. It is still need further study whether the leading factor affecting the grayscale is precipitation or the temperature. |
