摘要
大麦地一带中泥盆统产有数层透镜状煤层，其中角质体含量一般＞７５％，而且不同富煤点煤中角质体类型、含量、结构特点都不相同，存在明显的分异现象。这种分异现象反映出早期陆生植物对环境的适应和生态特点，是聚煤环境、植物类型和生态等因素综合作用的结果。本文从煤岩学、古植物学及沉积环境分析入手，探讨了它们之间的成因联系及由此反映出的早期维管植物的生态特点。
There are several lenticular coal seams occurred in Middle Devonian around Damaidi,in which the content of cutinite is >75% in general,the type,content and texture of cutinite in different coal rich points are different,and the obvious differentiation phenomena are presented,reflecting the adaptability of early terrestrial plant to the environment and its ecological property.That is the result of comprehensive actions of the factors such as coal accumulating environment,plant type and ecology and so on.Starting from the coal petrology,palaeobotany and sedimentary environment analysis,in this paper the genetic telations among them and the ecological property of early vascular plant reflected from them are expounded.
