| 摘 要： | 根据《山东珍稀濒危树种种质资源名录》及种质资源调查信息,选取招虎山具有代表性的8个珍稀濒危树种作为分析对象,在查阅相关资料及提前寻访的基础上,调查珍稀濒危树种的分布地点、伴生植物、种群数量、海拔高度、立地条件及人为活动影响程度。结果表明,8个珍稀濒危树种存在单株、零星及片状等多种分布类型,伴生植物以赤松、落叶松、栎类、胡枝子、大花溲疏、水榆花楸等为主。海拔约300 m的植物多样性最为丰富。所选取树种在坡地中部均有野生分布,尤其是该部位阳坡适生树种更为广泛。人为活动影响较多的区域主要分布在景点、游览线路及村落等地,各珍稀濒危树种野生分布地点处于沟谷及坡地下部的受影响较为显著,处于山脊及坡地上部的所受影响相对较小。

| Abstract: | According to the List of Germplasm Resources of Rare and Endangered Tree Species in Shandong and the investigation information of germplasm resources,8 representative rare and endangered tree species of Zhaohu Mountain were selected as the objects of analysis.On the basis of consulting relevant materials and looking forward in advance,the distribution of rare and endangered tree species,associated plants,population size,altitude,site conditions and human activities were investigated.The results showed that 8 rare and endangered tree species were found in individual,scattered and patchy types,and its associated plants mainly including Pinus densiflora,Larix gmelinii,Oak tree species,Lespedeza bicolor,Deutzia grandiflora,Sorbus alnifolia and so on.Plant diversity was the most abundant at 300 m above sea level.The selected tree species in the middle slope have a wild distribution,especially the parts on tree species more widely.Influence of human activities in many areas were mainly distributed in the scenic spots,tour routes and villages,the rare and endangered species of wild distribution sites located in the lower part of the slope gully and more significantly affected in the upper slope of the ridge,and the impact was relatively small. |
