摘　　要：根系生物量是植物光合产物向地下器官分配的重要组成部分,其分配机制受遗传因素与多种环境因子共同影响。近年来,有关林木根系研究受到广泛关注。文中基于前人研究报道,从遗传因素、环境因子、土壤微生物、邻株竞争等方面对林木根系生物量分配的影响机制进行剖析与综述;同时,阐述当前表征生物量分配机制的主要理论在根系研究中的应用概况,提出目前林木地下生物量研究中的不足与未来研究展望,以期为今后开展相关研究和实际应用提供参考。Root biomass is an important component of plant photosynthate allocated for the underground organs, which is jointly affected by genetic factors and various environmental factors. In recent years, the research on trees root system have received extensive attention. Based on literature available, the paper analyzes and reviews the influence mechanisms of trees root biomass allocation from the aspects of genetic factors, environmental factors, soil microorganisms and adjacent plant competition. At the same time, the application of the influence mechanisms in the research on root system is expounded using the main theory of biomass allocation mechanism. The deficiencies in the current researches on underground biomass of trees are discussed, and the future research directions are prospected, with the expectation to provide reference for the future related research and practical application.
