摘      要：Glacial meltwater runoff is a dynamic *** the one hand,nutrient concentration changes as it flows from upstream to downstream,and on the other hand,bacterial community structure changes due to its contact with nearby soil during the flow *** studied meltwater and soil in the Midre Lovénbreen glacier region,to explore changes in bacterial diversity as meltwater flows,and the relationship between meltwater and soil bacterial *** glacial meltwater flows from upstream to downstream,the relative abundance of dominant bacterial groups *** addition,we found that during the flowing process,nutrient exchange and bacterial contact had occurred between the meltwater runoff and the *** a result,the distribution patterns of some bacteria in the meltwater are very similar to those in the ***,we combined distance-based redundancy analysis and weighted correlation network analysis to show that NO_(3)^(-)-N and NO_(2)^(-)-N are the most two significant factors affecting glacial meltwater and soil,*** results suggest that in such a close-knit ecosystem,the interaction of glacial meltwater with soil,as well as environmental factors,together determine bacterial community composition.
