中文摘要：

通过实地考察和采样,应用新遗迹学,研究了滦河三角洲的现代造迹生物及其遗迹的组成与分布特征。研究结果表明：在现代滦河三角洲沉积中,造迹生物种类及其遗迹的分布在三角洲平原环境中主要受淡水影响,而在三角洲前缘环境中主要受潮汐作用的影响。该成果不仅丰富了我国新遗迹学的研究内容,而且还能为地史时期三角洲沉积环境中生物遗迹群落及其形成背景研究乃至古生态环境重建提供现实实证科学依据。

英文摘要：

Through field investigation and sampling,and applying neoichnology,the paper studied modern biogenic traces maker and their traces composition and distribution character in Luanhe delta. The research results showed that in the modern Luanhe river delta deposit,the trace-maker and their trace distribution in the delta plain environment were mainly affected by fresh water,and that in the delta front environment were mainly influenced by tidal action. The results not only enrich the neoichnological research in China,but also provide a real empirical scientific basis for studying the ichnocoenosis and their formation background of delta sedimentary environment in geological history,and even for the ecological environment reconstruction.
