林木根系是森林生态系统的重要组成部分,其在土壤改良中对土壤肥力、土壤结构及抗蚀性的生态作用早已引起人们的关注.近年来,从恢复生态学和全球生态学的角度来研究林未根系在森林生态系统物质循环中的作用以及根系分布在森林演替中的生态作用也成为了热点.根系与其周围环境是相互联系、相互作用的,林木根系的形态、分布除受林木自身的遗传特性影响外,还受大气CO_2浓度、土壤的物理性质等因素的影响.在目前的研究基础上,很有必要深入的对调控因子以及群落内的种间、种内竞争关系等林木根系生态作用做进一步研究.

Root system is an important part of forest ecosystem, and much attention have been paid to the ecological functions of tree root system on soil fertility, soil structure and erosion resistance in the soil. Furthermore, from the perspective of restoration ecology and global ecology,the function of root in the material cycle of the forest ecosystem, and the ecological role of root distribution in forest succes-sion are also becoming research focuses. Root system and its surrounding environment are interrelated and interactive. The configuration and distribution of tree root system were affected not only by trees gene characteristic, but also by factors such as CO_2 concentration of atmosphere and soil physical prop-erties. Based on the present research, further research needs to be carried out on tree root ecology, such as control factors and relationship of competition between same or different population of plants.
