摘要: 林下植被是森林生态系统的重要组成部分。研究林下植被的生物量特征及其生态作用对深入研究森林生态系统结构和功能有重要意义。本文归纳了森林林下植被的生物量分布特征与森林的类型、龄级和林分特征等因子之间的变化关系,分析了林下植被在维持森林生态系统营养元素循环、保持水土、指示森林环境状态变化、影响森林林分的生理生态特征和森林演替、保护动物的栖息地以及维持生态平衡等方面的主要生态作用。

Abstract: Understory vegetation is one of the main components of forest ecosystem. To understand the characteristics of understory biomass and its ecological effects is of significance in studying the structure and function of forest ecosystem. This paper summarized the relationships of the distribution of understory biomass with forest type, forest age class, and stand characteristics, and discussed the main roles of understory vegetation in maintaining nutrients recycling, preventing soil erosion, indicating forest environment change, affecting forest ecophysiological characteristics and succession, protecting animals inhabit, and keeping ecological balance.
