摘　　要：Precipitation scenario alteration leads to grievous ecological consequences in ecosystems,especially on the Qinghai-Tibet Plateau.Bacterial and fungal community and their abundant and rare taxa in soil ecosystems may respond differently to the changed precipitation.Therefore,more attention needs to be paid to the sensitivity of bacteria and fungi and their abundant and rare taxa to precipitation shifts.The responses of bacterial and fungal populations and their abundant and rare taxa concerning diversity,assembly,and interactions to manipulative changes of precipitation were explored via imitating no precipitation,little precipitation,and medium precipitation using 16S rRNA gene and ITS amplicon sequencing.The results indicated that the change rate of fungal Simpson diversity with precipitation was higher than that of bacteria.The slope of the modified stochasticity ratio(MST)value of fungi to precipitation was steeper than that of bacteria.The Simpson diversity and the MST value of abundant and rare taxa within bacteria had no difference with precipitation.In contrast,those of abundant taxa within fungi varied more than rare ones with precipitation.By unveiling the differential responses of microbial populations with discrepant characteristics,this study allowed us to understand the different microbial communities responding to rainfall on the Qinghai-Tibet Plateau.
