摘要

Soil samples from the intertidal zone of Daliao River, Northeast China, were collected in three seasons (autumn, L1; winter, L2; and spring, L3) to evaluate the diversity and structure of bacterial community using high-throughput sequencing. Soil physicochemical characteristics varied greatly with seasons, and the potential nitrification rates were detected in the range of 1.04-2.71 mu g NO3--N.g(-1) dry soiLh(-1) with the highest rate in spring (L3). Soil bacterial communities also differed seasonally, and nitrogen nutrients were the important variables affecting the bacterial communities as demonstrated by distance-based redundancy analysis and Mantel tests. Pmteobacteria was the predominant phylum in soils showing a descending trend from L1 to L3. Woeseia and Ignatzschineria, both affiliating with Gammaproteobacteria, were the two most dominant genera, but they exerted different seasonal variations. The predicted functional profiles revealed 6 major nitrogen cycling processes, and the functional genes in relation to denitrification process were dominant in intertidal soils.
