摘要
通过野外第一手资料,总结了渭北煤田早二叠世化石植物群落特征、群落演替规律及植物地理特点。力图从定量与半定量分析的角度,勾勒在该区早二叠世早期山西组发现的26属75种植物化石和早二叠世晚期下石盒子组中发现的30属65种植物化石之古生态轮廓。
Based on the firsthand informations from field, the paper summarizes the fossil plant com-munities, the community replacing rules and the phytopaleogeography Characteristics of early Permi-an in Weibei coal field From the points of the quantitative analysis and the semi-quantitative methodin paleoecology,the aufhor strives to draw the phytopaleoecology outline of the fossil plants which in-clude 75 species of 26genera discovered in Shanxi Formation, 65 species of 30 genera in lower ShihotseFormation.
