| 摘 要： | 许多气候环境变化曲线像自然界的曲线一样存在复杂的变化。尝试用计算海岸线分形维数的方法分析了渭南黄土剖面碳酸盐质量分数变化轨迹的分形特征，发现其中也存在分形维数，这种分数维也可以用来表示碳酸盐质量分数变化的复杂性。渭南黄土剖面碳酸盐质量分数变化轨迹的分形存在两段性，而且在黄土和古土壤中也存在差异

| Abstract: | Many of the climatic curves obtained by climatologists and others are as complex as some of the natural curves, such as coastal line. The fractal characteristic s of mass fraction of CaCO3 from Weinan Loess Profile at Weinan, Shaanxi Provinc e, is analyzed using the method for calculating the fractional dimension of coas tal line. It is found that there exists fractal characteristics in mass fraction of CaCO3 from Weinan Loess Profile and this kind of fractional dimension can al so be used to characterize the complexity of the variation of mass fraction of C aCO3, as well as climatical and environmental evolution. The mass fraction of Ca CO3 from Weinan Loess Profile have two fractional dimensions. There probably exi sts some differences in this kind of fractional dimension between loess units an d paleosol units. |
