Fig. 5

Non-metric multidimensional scaling (NMDS) analysis of different soil microbial communities involved in nitrification and denitrification under different salt and alkali stresses in a calcareous desert soil. The communities were a amoA-AOA, b amoA-AOB, c nirK, d nirS, e and nosZ. CK, control treatment without salt or alkali stress; CS, NaCl stress treatment; SS, Na2SO4 stress treatment; AS, Na2CO3 + NaHCO3 stress treatment
