【摘要】 通过查阅相关资料,结合实地调查,采用典型样地法对保定市蚕姑坨景区风景林结构特征进行了研究。结果表明:(1)通过群落物种重要值分析确定群落优势种,可将蚕姑坨景区风景林主要群落类型划分为侧柏林、黄连木林、蒙古栎林、栾树林、荆条灌丛、荆条杂木灌丛和毛黄栌灌丛。各群落类型物种多样性排序为黄连木林>毛黄栌灌丛>栾树林>蒙古栎林>荆条杂木灌丛>侧柏林>荆条灌丛。(2)景区中乔木树种的径级大多集中分布在8.1～16.0cm的范围内,乔木树种树龄偏小,在水平结构上,具有很大的发展潜力。(3)从群落垂直方向上看,景区多数风景林群落成层现象明显,可分为乔木层、灌木层和草本层。(4)由于景区多为落叶阔叶植物,在季相变化方面,色彩景观主要以春夏秋季为主。更多还原

【Abstract】 Based on the relevant data and combined with the field investigation,this paper studies the structural characteristics of the scenic forest in the Cangutuo Scenic Area of Baoding City by using the typical plot method. The results showed that 1)the dominant species of the community were determined by the analysis of the important values of the community species,and the main community types of the scenic forests in the Cangutuo Scenic Area could be divided into the Side Berlin,the Pistacia Forest,the Mongolian Oak Forest,the Eucalyptus Forest,the Vitex Shrub,the Vitex Weedtree Shrub and Coggygria Var Pubescens Shrub. The species diversity of each community type was the Pistacia Forest > Coggygria Var Pubescens Shrub > the Eucalyptus Forest > the Mongolian Oak Forest > the Vitex Weedtree Shrub > Side Berlin > Vitex Shrub. 2)Most of the diameters of arbor species in the scenic spot are concentrated in the range of 8.1 to 16.0 cm. The arbor species are younger and have great development potential in horizontal structure.3)From the vertical direction of the community,most scenic forest communities in the scenic area have obvious layering phenomena,which can be divided into arbor layer,shrub layer and herb layer. 4)In terms of seasonal variation,the scenic spots are mostly deciduous broad-leaved plants,and the seasonal color landscape is mainly in spring,summer and autumn.更多还原
