Characteristics of Diatom Distributions of the Surfacial Sediments in Tianjin Shallow Sea Area and the Implications for Holocene Geoenvironmental Changes
Taking the intertidal zone, shallow sea and the contiguous coastal lowland, Tianjin section of west Bohai Bay, as the studying area, two major works have been done in this thesis. Firstly, diatom identification, statistics and analysis of 95 surfacial sediment smaples have been systematically carried out. Diatom assemblages, dominant species, their distribution characteristics and relationship with the environmental factors were found out. Transforamtion between dominant species, assemblages and environment...
