Climate warming is predicted to affect temperate forests severely, but the response of fine roots, key to plant nutrition, water uptake, soil carbon and nutrient cycling is unclear. Understanding how fine roots will respond to increasing temperature is a prerequisite for predicting the functioning of forests in a warmer climate. We studied the response of fine roots and their ectomycorrhizal (EcM) fungal and root-associated bacterial communities to soil warming by 4 °C in a mixed spruce-beech forest in the Austrian Limestone Alps after 8 and 14 years of soil warming, respectively. Fine root biomass (FRB) and fine root production were 17% and 128% higher in the warmed plots, respectively, after 14 years. The increase in FRB (13%) was not significant after 8 years of treatment, whereas specific root length, specific root area, and root tip density were significantly higher in warmed plots at both sampling occasions. Soil warming did not affect EcM exploration types and diversity, but chan...气候变暖预计会对温带森林造成严重影响，但作为植物营养摄取、水分吸收以及土壤碳与养分循环关键组分的细根（fine roots），其对变暖的响应机制仍尚不明确。明确细根如何响应温度升高，是预测变暖气候下森林生态系统功能的前提条件。本研究以奥地利石灰岩阿尔卑斯山区的云杉-山毛榉混交林为研究对象，分别在土壤增温4℃并持续8年、14年后，探究了细根及其外生菌根（ectomycorrhizal, EcM）真菌、根相关细菌群落的响应特征。增温14年后，增温样地的细根生物量（FRB）与细根生产量分别较对照提升17%与128%；增温处理8年后，细根生物量增幅（13%）未达显著水平，但两次采样中增温样地的比根长、比根面积及根尖密度均显著高于对照样地。土壤增温未对外生菌根的探索类型与多样性产生显著影响，但……
