摘要

林下植被匮乏是南方红壤丘陵区退化马尾松林生态系统普遍存在的一个突出问题。恢复退化马尾松群落的林下植被对于扭转该地区低效马尾松林的逆向演替

改善当地生态环境具有重要意义。分析了马尾松林下植被匮乏的主要成因

并从土壤养分、土壤物理性状、夏季高温和季节性干旱、土壤酸化和人为干扰等方面综合探讨了林下植被恢复的主要限制性因素。从如何控制林地水土流失

改良退化林地土壤及减少人为干扰3个方面提出了退化马尾松林下植被恢复的对策。总结了到目前为止林下植被恢复较为成功的几种模式

以期为今后南方红壤侵蚀区退化马尾松林的改造和修复提供参考。

Abstract

The scarcity of undergrowth vegetation has already become a common but outstanding problem

existing in a large portion of Pinus massonianaforest ecosystems in the eroded red soil area of southern China.Accordingly

making every effort to restore the undergrowth vegetation in degraded masson pine community is of great significance for reversing regressive succession of inefficient Pinus massonianaforests and improving local ecological environment.This paper analyzed the main causes leading to the problem of undergrowth vegetation scarcity in some Pinus massoniana ecosystems and then presented a comprehensive discussion on the limiting factors to undergrowth vegetation recovery from several aspects

such as soil nutrient status

soil physical properties

high summer temperature

seasonal drought

soil acidification and human disturbances.Several effective countermeasures and successful recovery models

which had already been proven by practices

were put forward to solve the problems of how to control soil and water loss in woodland

improve degraded woodland and reduce human disturbances.It is expected to provide references for future research on the transformation and restoration of degraded Pinus massoniana forests in the eroded red soil area of southern China.
