中文摘要	测定和分析了甘肃省金昌市金川区荒漠草原土壤微生物数量、微生物生物量和土壤酶活性。结果表明:同层土壤3大类微生物(真菌、细菌和放线菌)数量、土壤微生物量碳和氮含量及4类土壤酶(蔗糖酶、脲酶、磷酸酶和过氧化氢酶)活性均表现为盐爪爪(Kalidium oliatum)群落大于骆驼刺(Alhagi sparsi folia)群落,而土壤微生物量磷含量相反;同一植物群落,不同层土壤微生物数量(除骆驼刺群落中的真菌亚表层最高外)、土壤微生物量碳、氮、磷含量及土壤酶活性(除骆驼刺群落中脲酶呈现高一低一高一低趋势外)均呈现随土层的加深而降低的趋势;金川区荒漠草原不同植物群落不同空间层次土壤微生物数量、微生物生物量和各种酶之间有不同程度的相关性。
英文摘要	Soil microbial quantities, microbial biomass and enzyme activity of desert steppe ecosystem under different plant communities in desert steppe in Jinchang, Gansu, China were studied in this paper. The results showed that the changes tendency of soil microbial quantities, microbial biomass C, N and enzyme activity of community dominated by Kalidium foliatum were much higher than that of the community dominated by Alhagi sparsifolia, while the microbial biomass P opposite. The number of soil microbial (bacteria and actinomycetes), microbial biomass (C, N, P) and enzyme activity decreased with the soil depth in vegetation coverage, The soil urease showed a "high-low-high-low" trend and maximum fungus in the subsurface layer of soil in community of A. sparsifolia grassland. Meanwhile, the result of correlation analysis indicated that there were significant correlation among soil microbial quantities, soil microbial biomass and soil enzyme activity.
