摘要: 采用开顶式生长室(Open-top chamber,OTC)连续8 a(2008~2015年)长期模拟温度升高,研究滨海芦苇湿地不同土壤深度,及两种代表植物芦苇(Phragmites australis)和白茅(Imperata cylindrical)根际、非根际土壤可培养微生物数量变化对长期增温的响应。结果表明:(1)相对于对照,长期增温导致土壤可培养微生物的数量显著增加。其中,增温对土壤表层细菌、真菌的数量影响显著,细菌在第一层的增幅最大,增加率为34.16%,真菌在第三层的增幅最大,增加了64.42%。增温对20~40 cm土层放线菌影响显著,其中在第二层达到最大增加率59.47%;(2)长期增温对芦苇根际土壤微生物的根际效应变化的影响不大,表现为各土层芦苇根际效应增温<对照,而白茅根际真菌和放线菌分别在第二层和第三层有显著差异;(3)不同的植物类型,其根际可培养微生物数量及根际效应对长期增温的响应不一致,表现为芦苇和白茅根际土壤可培养微生物数量及根际效应的增加幅度不同,这可能与植物不同类型,根际分泌物种类、数量的差异有关。
