| 摘 要： | 在响叶杨的主产区贵州黔中永乐、麻江等地对响叶杨天然林分和人工间伐后的纯林的群落结构及种间关系进行了研究。结果表明:在响叶杨天然林分中,响叶杨在空间和资源竞争中呈优势地位,其伴生树种处于劣势地位,导致伴生树种被逐步淘汰,产生它疏现象,从而形成小片响叶杨纯林或响叶杨占主导地位的稳定响叶杨群落次生混交林群落;通过对非目的树种的间伐,避免种间竞争,可提高林分的经济价值,促进群落向顶级发展。

| Abstract: | This paper researched the structure of community and the interspecies competition of Populus adenopoda natural stand and pure forest after manual thinning in main producing areas of Qianzhong,Yongle,and Majiang in Guizhou,The results showed that in P.adenopoda stands,it showed dominance in space and resource competitions,its companion species was on inferior position,which led to washing out other companion species by it,and directing into its scanty,so as to form the small area of P.adenopoda pure forest o... |
