细根（< 2 mm）是森林生态系统碳和养分循环和积累的重要组成部分。本文综述了欧洲三种主要树种欧洲山毛榉（Fagus sylvatica L.）挪威云杉Picea abies L.喀斯特。）和欧洲赤松（Pinus sylvestris L.），以确定物种之间、植被带内和植被带之间的差异，并显示根系生物量与气候、立地和林分因素之间的关系。收集的文献包括36山毛榉，71云杉和43松树林的数据。山毛榉细根平均生物量为389 g/m ~（-2），云杉和松树分别为297 g/m ~（-2）和277 g/m ~（-2）。松树林分的数据支持这一假设：根生物量是在温带高于在寒带。结果表明，落叶乔木的根系生物量高于针叶树。根系生物量与立地肥力特征之间的相关性似乎是种特异性的。土壤酸度与根系生物量无相关性。山毛榉细根。生物量随林龄的增加而减少，而松树根系生物量随林龄的增加而增加。乔木层细根生物量。林分根系生物量与林分特征的相关性优于林分水平。结果表明，细根生物量与地上生物量之间存在密切关系。
Fine roots (< 2 mm) are very dynamic and play a key role in forest ecosystem carbon and nutrient cycling and accumulation. We reviewed root biomass data of three main European tree species European beech, (Fagus sylvatica L.), Norway spruce (Picea abies L. Karst.) and Scots pine (Pinus sylvestris L.), in order to identify the differences between species, and within and between vegetation zones, and to show the relationships between root biomass and the climatic, site and stand factors. The collected literature consisted of data from 36 beech, 71 spruce and 43 pine stands. The mean fine root biomass of beech was 389 g m(-2), and that of spruce and pine 297 g m(-2) and 277 g m(-2), respectively. Data from pine stands supported the hypothesis that: root biomass is higher in the temperate than in the boreal zone. The results indicated that the root biomass of deciduous trees is higher than that of conifers. The correlations between root biomass and site fertility characteristics seemed to be species specific. There was no correlation between soil acidity and root biomass. Beech fine root. biomass decreased with stand age whereas pine root biomass increased with stand age. Fine root biomass at tree level. correlated better than stand level root biomass with stand characteristics. The results showed that there exists a strong relationship between the fine root biomass and the above-ground biomass.
