摘要
本文试用平台式扫描仪和GetData Graph Digitizer软件相结合的方法,对产于兰州盆地渐新统二维形态的化石山杨(Populus davidiana Dode)叶片进行数字化,获得其叶相的主要基本参数数据。然后用Golden Software Grapher软件对数据进行检验,重建的化石形态与原叶片宏观特征吻合程度很好。这表明:对于二维形态的叶化石,利用相关软件获取图形数据是一种可行的方法,这也可为叶片化石形态定量化分析和重建3D化石图像用于博物馆展览和科普宣传提供基础的数据。
The digitalization on fossil Populus davidiana Dode leaf, which is two-dimensional shape and from the Oligocene in the Lanzhou Basin, has been carried out by making use of the combination of the flatted scanner and GetData Graph Digitizer software, and the basic data about the main parameters of leaf physiognomy were obtained. The reconstructed fossil shape well dovetails with that of the original fossil, which has been tested by the Golden Software Grapher software. It shows that the method of getting data from the two-dimensional shape fossil leaves with software is practical, and these basic data can been used for quantitative analysis on physiognomy and fossil leaf 3D reconstruction for popular science propaganda.
