摘要
作者通过对新疆北部泥盆纪火山－沉积岩系中６个习性类、９种遗迹群落中２８个遗迹属的野外和室内观测，首次从遗迹化石个体或群体间排列状态和空间分布角度提出了遗迹化石共生组合关系的概念，并将其区分为３类１５型．遗迹化石共生组合关系的研究对详细的古环境、古生态分析和对蕴含在遗迹化石中尚未揭示的奥秘的探索有重要意义．
Through having investigated twenty-eight ichnogenera grouped into six ethological types and nine ichnocommunities of the Devonian volcanic sedimentary successions in Northern Xinjiang,the author first proposes the concept of association relationships among trace fossils in terms of the spatial arrangement and distribution of individual and massive trace fossils.Association relationships among trace fossils which are subdivided into three class and fifteen subclass are recognized in the Devonian.The author'S studies indicate that the investigating of association relationships among trace fossils possesses important significances for reconstructing palaeoenvironments and palaeoecology in detail and discovering the mysteries which have been not discovered in trace fossils so far.
