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
Many climate change curves have the same complex changes as those in nature. This paper attempts to analyze the fractal characteristics of the carbonate mass fraction in the Weinan loess by calculating the fractal dimension of the coastline and finds that there are also fractal dimensions which can also be used to indicate the complex change of carbonate mass fraction Sex. The fractal distribution of carbonate mass fraction in Weinan loess section has two stages, and there are also differences in loess and paleosol
