Abstract
Diatom-inferred changes in past water levels and the evolution of peatlands during the Holocene period are investigated in the Honghe National Natural Reserve (HNNR), which is located on the Sanjiang Plain of Northeast China. This investigation began with analyses of fossil diatoms and the corresponding water environments from the surface sediments of peatlands. The detrended correspondence analysis (DCA) and redundancy analysis (RDA) methods show that the water level is one of the major factors that drives the distribution of diatom assemblages in the peatlands of the HNNR. A diatom-based inference model is developed, and the Holocene water levels are reconstructed based on the inference mo..
