摘要
对甘肃省成县刺叶栎的生长环境、种群数量和结构特征进行实地调查,结果表明:刺叶栎在成县的分布较广,大多分布在阳坡的中坡和上坡,以土层较薄山脊分布较多.但种群数量不多,幼树数量不足,种群结构在短期内比较稳定,但容易衰退,必须加以重视.对天然刺叶栎资源的保护措施主要是疏伐其他建群树种,增加透光,促使刺叶栎结实和加快更新;在城市园林绿化应用中,必须解决人工引种繁殖的技术,不能以破坏天然刺叶栎资源为代价.
Abstract
The growth environment,population quantity and structure characteristics of Quercus spinosa in Chengxian County were investigated.The results showed that Quercus spinosa was widely distributed in Chengxian County,mostly located in middle and upper slopes in sunny slope.The population quantity was not much and saplings were insufficient.Population structure was relatively stable in the short term,but it was easy to decline,which must be paid attention to.The main measures for protecting natural Quercus spinosa resource included:thinning other tree species,increasing light transmission,promoting seed-setting and updating;in the application of urban landscape,the technology of artificial introduction and propagation must be solved,and the resource of natural Quercus spinosa can not be destroyed.
