摘要/Abstract

摘要： 植物群落斑块化是天然放牧草地最基本的特征之一.为探索植物群落斑块化对土壤微生物群落组成及多样性的影响,本研究以宁夏荒漠草原为研究对象,采用磷脂脂肪酸(PLFA)法对比分析了不同植物群落微斑块内土壤微生物生物量和群落结构特征的变化.结果表明: 1) 4种植物群落微斑块内土壤微生物种类丰富,且都表现为细菌含量最高,真菌和放线菌含量较少,革兰氏阳性菌含量高于革兰氏阴性菌;2)4种植物群落中,甘草微斑块的土壤微生物总量显著高于猪毛蒿、苦豆子和黄芪;3)冗余分析表明,磷脂脂肪酸总量、革兰氏阳性菌、革兰氏阴性菌、真菌、厌氧菌、真菌/细菌均与土壤有机碳呈显著正相关,与pH呈显著负相关,表明土壤有机碳、pH是荒漠草原土壤微生物生长和发育的重要影响因素.

Abstract: Vegetation patch is one of the most basic characteristics of natural grazing grassland. To explore the effects of vegetation patch on soil microbial community, the changes of soil microbial biomass and community structure under four different vegetation patches in Ningxia desert steppe were quantified using phospholipid fatty acid (PLFA) analysis. The results showed that: 1) Soil microbial groups were abundant in vegetation patches, with the highest bacterial content, low fungal and actinomycete content, and the Gram-positive bacteria content being higher than that of Gram-negative bacteria in the patches of the four plant communities; 2) The total soil microbial biomass of Glycyrrhiza uralensis patch was significantly higher than that of Artemisia scoparia, Sophora alopecuroides, and Astragalus melilotoides patches; 3) Total PLFAs, Gram-positive bacteria, Gram-negative bacteria, fungi, anaerobic bacteria and fungi/bacteria were significantly positively correlated with soil organic C, and significantly negatively correlated with soil pH, indicating that soil organic C and pH were important factors affecting the growth and development of soil microorganisms in desert steppe.
