Abstract:: The biological soil crusts play the important roles in soil nutrients and microbial metabolism. To further clarify the constraining nutrients and influencing factors of microbes during the development of biological soil crust. Bare soil(CK), light-colored algal crust(LA), dark algal crust(DA), alga-moss mixed crust(AM)and mossy crust(M)were selected as the research samples, we analyzed the status of carbon(C), nitrogen(N), phosphorus(P)and extracellular enzyme activities of different types of biological soil crusts, and quantified the metabolic limitation of microbes by extracellular enzymatic stoichiometry. The results showed that the contents of C, N, P and the sizes of microbial biomass C, N, P of LA, DA, AM and M were significantly higher than those of CK(p<0.05), and the contents of SOC, TN, TP and the sizes of microbial biomass C, N, P increased gradually in the order: CK<LA<DA<AM< M; the sizes of microbial biomass C, N and P in the moss crust were 18.3, 27.6 and 14.1 times of those in CK, respectively. The development of biological soil crusts significantly increased the activities of C, N and P cyclic enzymes, and the redundancy analysis showed that nutrients of the cruts were closely related to the enzyme activities. In addition, the results from enzymatic vector model showed that the development of biological soil crusts could lead to the increase of relative C limitation to microbes and decrease of relative P limitation to microbes, respectively, and microbes were affected by the contents of available nutrients. The results of partial least squares path model also indicated that the type of biological soil crust indirectly affected the microbial metabolism limitation. In general, changes in the types of biological soil crusts will improve nutrient status and microbial biomass of biological soil crusts, and the supply of nutrient resources will cause changes in microbial nutrient metabolism in biological soil crust.
