森林群落具有成层结构,一般分为乔木层、下木层、草本层、地被层。这样完整的层次,能保持生态平衡,促进体木的生长。然而,当前营造各种人工林时,忽视了这样层次的配置,只注重乔木树种的建群,不注意下木的营造。为了引起人们对下木的重视,加速林木生长,维护生态平衡,现根据我们的调查和有关资料,谈谈我区下木的种类和作用,供参考。据调查,我区下木主要有:山茶科的黄端木、柃木、油茶、茶、扬桐;豆科的大叶黄檀、胡枝子、美丽胡枝子、紧穗槐、山槐、宜昌木兰、华东木兰、锦鸡儿;蔷薇科的山桃、木梅、陷脉、石楠、石斑木;马鞭草科的大青、紫珠、华紫珠、广东紫珠、臭黄荆;樟科的
Forest community has a stratified structure, generally divided into tree layer, wood layer, herb layer, ground cover. Such a complete level, to maintain ecological balance and promote the growth of body wood. However, at present, when creating various kinds of plantations, they ignore the configuration at such levels and focus only on the establishment of tree species and pay no attention to the construction of trees under them. In order to arouse the people’s attention to the understory, accelerate the growth of trees and maintain the ecological balance, we will discuss the types and functions of understory in our area according to our survey and relevant information for reference. According to the survey, the main subordinate areas of our district are: yellow Duanmu, Alnus cremastogyne, Camellia, tea, Yangtong in Camelliaceae; Magnolia grandiflora, Lespedeza rhododendron, Lespedeza macrophylla, Sophora japonica, , East China Magnolia, Caragana; Rosaceae peach, plum, submarine vein, heather, grouper wood; Verbenaceae Daqing, Zi Zhu, Hua Zhushu, Guangdong purple beads, stinkbug; Lauraceae
