安徽省石灰岩山地适生树种的选择

以皖东、皖南、皖北的典型石灰岩山地天然次生林群落为研究对象,在群落调查、更新状况调查分析的基础上,探讨了安徽省石灰岩山地的适生树种.结果表明青檀、榉树、朴树、琅琊榆、醉翁榆等榆科树种为皖东石灰岩山地造林绿化的最适树种;麻栎、枫香、黄连木、马尾松、湿地松、侧柏、刺柏、青檀为皖南石灰岩山地造林宜选树种;栓皮栎、板栗、麻栎、青檀、侧柏、杜梨、泡桐等树种为皖北石灰岩山地的造林树种.该研究将为加速北亚热带石灰岩山地绿化提供了可靠依据.

Tree Species Selection in the Limestone Mountainotis Areas of Anhui Province

Based on the analysis of site type,forest community and regeneration of the natural secondary community of the typical limestone mountainous areas in the eastern,southern and northern of Anhui Province,the adaptive tree species for the areas were selected in this paper.The results showed that the trees of Ulmaceae family such as Pteroceltis tatarinowii,Zelkova Schneideriana,Celtis tetrandra,Ulmus chenmoui,and Ulmus gaussenii were the best species for the limestone areas of Eastern Anhui Province.The tree species of Quercus acutissima,Liquidamba formsana,Pistacia chinesis,Pinus massoniana,Pinus elliottii,Platycladus orientalis,Juniperus formosana,and Pteroceltis tatarinowii were the adaptive species in the southern of Anhui Province.And the tree species like Quercus variabilis,Castanea mollissuna,Quercus acutissima,Platycladus orientalis,Pteroceltis tatarinowii,Pyrus betulaefolia,and paulownia tomentosa were the best species in the northern of Anhui Province.
