英文摘要	To investigate the effects of different utilizationmethods on the ratio characteristics of soil C, N, P and enzyme activities of grassland soil is of great significance for the sustainable utilization of grassland. In this study, the effects of different utilization methods on soil C, N, P rate and enzyme activities were investigated in artificial grasslands treated with grazing grassland (GG), mowing grassland (MG) and enclosed grassland (EG). The results showed that: (1) the contents of soil organic carbon (SOC), total phosphorus (TP) and ammonium nitrogen (NH4+-N) were EG > GG > MG; the contents of total nitrogen (TN), alkaline nitrogen (AN) and nitrate nitrogen (NO3- -N) were GG > EG > MG; the contents of available phosphorus (AP) and C:N were EG > MG > GG; the contents of C:P and N:P were MG > GG > EG; (2) beta-1,4-Glucosidase ( beta G) and beta-1,4-N-Acetylglucos-Aminidase (NAG) activities were GG > EG > MG, acid phosphatase (ACP) was EG > MG > GG, Leucine Aminopeptidase (LAP) was MG > EG > GG, C:NEEAand C:PEEAwereGG > EG > MG, N:PEEAwasGG > MG > EG; (3) redundancy analysis showed that AN (F = 4.90, p = 0.01) was an important driver of soil enzymes. We concluded that there were significant differences in soil C, N, P, enzyme activity and their ratio characteristics under different grassland uses. EG is closer to the standard ratio of global soil ecosystems. Therefore, reducing soil disturbance and optimizing fertilization are effective ways to improve soil enzyme activity and maintain good soil nutrient circulation.
