Abstract：Biogenic traces records are the results of the interaction of organisms and environment and the good indicator of sedimentary environment，climate and the ecological environment.The composition and distribution characters of biogenic traces and their makers in modern point bar deposits of the Middle-Lower Reaches of Yellow River in Jiaozuo area，Henan Province， are as follows:(1)The main trace-makers on point bar near riverbed are birds and Coleptera.The main traces are the feeding traces of Coleptera and birds on the bedding plane.(2)The main trace-makers on distal point bar and temporal channels are insects as mole crickets，crickets and worms.The main traces are the U-shaped，Y-shaped，W-shaped and vertical feeding burrows of mole crickets，crickets and worms in intrastratal bedding as well as F-shaped and Y-shaped feeding and crawling traces developed on bedding plane.(3)The main trace-makers on flood plain are ant lion，cricket，field mouse and spiders.The biogenic traces are characterized by the J-shaped and funnel shaped feeding and dwelling burrows.By means of grain size analysis，admeasurements of total-organic-carbon，plant bacteria colony counting,the abundance and diversity of traces increase with decreasing grain size and increasing TOC in this study area.The depth of traces below the sediment surface is closely related to the food source and amount of bacteria in the sediments.This study is not only significant to identify the biogenic structures and can be applied to the study of fluvial sedimentary environment，ecology，palaeoichnology research，but also is available to the palaeoclimate，palaeoenviroment and palaeoecology reconstruction.
