摘要
本文在研究分析琅琊山天然森林群落演替趋势、榆科树种生理生态特性以及皖东石灰岩地区立地分类的基础上 ,探讨了皖东石灰岩山地的适宜造林树种 ,从而为加速北亚热带石灰岩山地的绿化提供理论依据。研究结果表明 ,青檀、榉树、琅琊榆、醉翁榆等榆科树种 ,由于在生理上对高钙、干旱的石灰岩生境有较好适应性 ,同时在群落演替过程中具有相对稳定性 。
This paper was based on the study of the physiological and ecological characters of main species within family of Ulmaceae, and the analysis of the soil type and climatic conditions in Mt. Lanya. The suitability of tree species there were also studied. The results showed that Pteroceltis tatarinowii, Zelkova schneideriana, Ulmus chenmoui, U.gaussenii, etc. in family Ulmaceae were the best species for limestone mountains in the eastern of Anhui Prvovince, because their physiological characters and succession suitability are adaptable to the high calcium and lacking water habitat.
