Abstract: The mineralization of soil microbial N, P and K varied withvegetation types, ranging from 20.24—33.36, 2.01—3.86 and 8.88--18.35mgkg dry soil, respectively.The amount of nitrogen mineralized from soil microbes wasclosely related to the biomass-C. The regression equation was y = 0.3761x+ 4.8455,r = 0.5519***(n = 60).The total C, N, P and K in soil microbial pool were 702.94—1150.58, 93.72—155.53, 10.95—20.27 and 34.03—70.35 kg·ha-1 the average values were 924.15+195.73, 117.27 + 25.52, 15.08+3.95 and 50.14+13.29 kg·ha-1 accounting for 3.00 + 1.13, 5.34 + 1.57,1.71+0.57 and 0.26 + 0.22% of the total soil C, N, P and K.The status of soil microbial pool nutrient in monsoon evergreen broadleaf forest was better compared with other vegetation types.
