成煤古气候研究进展:替代参数、方法与问题

ADVANCES IN STUDIES OF COALFORMING PALAEOCLIMATE: SUBSTITUTE PARAMETERS,METHODS AND PROBLEMS

总结和评述了成煤古气候分析中的主要替代参数（岩石学和沉积学参数、地球化学参数和古植物学参数）、数字模拟技术的现状、新进展及其局限性；指出建立各类替代参数数据库和参数的定量化，有利于成煤期的古气候重建，揭示古气候对聚煤作用的控制和建立古泥炭沼泽模式。

Palaeoclimate is part of a larger problem of understanding the origins of coal in different geological periods and palaeogeographic setting,as well as the formation of models of ancient coalforming environment.Based on the analyses of main literatures contributed to it in past two decades,a brief review on development and limitation of substitute parameters for palaeoclimate reconstruction,which include lithological and sedimentary,geochemical as well as palaeobotanical ones,is given in this paper.Numerous simulation technique using general circulation model (GCM) and FujitaZiegler model to retrodicting global palaeoclimate is also commented here.
