According to the identification of fossil woods, it shows that they all belong to Araucarioxylon, with the stage age of Qixia, though there are some anatomical differences among them; Following two mathematical clustering analysis methods-analysis of variance and CSDM curve, metrical numerical values are quantitatively analysed, then, skew value of curve and its relationship with leaf longevity are showed.

经过鉴定研究认为，本区的木化石均属于松柏类中的南洋杉型木属，为栖霞阶化石；应用方差分析、CSDM曲线相关分析等数学聚类分析方法，对木化石标本的测量数据进行了定量分析研究，探讨了曲线偏差值与叶寿命的关系，认为本区二叠纪木化石均为常绿树种-南洋杉型木，但有可能存在落叶树种，且生长年限有较大差异。
