摘      要：Human disturbances to soils can lead to dramatic changes in soil physical,chemical,and biological *** influence of agricultural activities on the bacterial community over different orders of soil and at depth is still not well *** used the concept of genoform and phenoform to investigate the vertical(down to 1 m depth)soil bacterial community structure in paired genosoils(undisturbed forests)and phenosoils(cultivated vineyards)in different soil *** study was conducted in the Hunter Valley area,New South Wales,Australia,where samples were collected from 3 different soil orders(Calcarosol,Chromosol,and Kurosol),and each soil order consists of a pair of genosoil and *** bacterial community structure was analyzed using highthroughput sequencing of 16S *** showed that bacterial-diversity decreased with depth in phenosoils,however,the trend is less obvious in genoform *** diversity was greater in phenosoils than genosoils,but the trend was reversed in ***,cropping not only affected topsoil bacteria community but also decreased its diversity in the *** community in topsoils was influenced by both soil orders and soil forms,however,in subsoils it was more impacted by soil *** Analysis of Principal Coordinates revealed that cropping increased the similarity of bacterial structures of different soil *** study highlighted the strong influence of agricultural activities on soil microbial distribution with depth,which is controlled by soil order.
