摘要：【目的】研究北京百花山国家级自然保护区植被群丛群系结构组成和生物多样性特征。【方法】本文以百花山国家级自然保护区森林、灌木及草甸群系为研究对象,选取代表性群丛设置样方,根据系统性与代表性原则,分别布设25块森林群落样方(包括蒙古栎林、华北落叶松林、胡桃楸林、油松林和白桦林)、10块灌木样方(包括胡枝子、绣线菊等)和30块草甸样方(包括野青茅、地榆等)进行实地调查,对群落组成、结构及生物多样性特征进行了调查和分析。【结果】草本植物以薹草属分布范围最为广泛。灌木以绣线菊属、雀儿舌头、胡枝子属等为优势物种,作为该地区的主要植被组成成分。乔木群丛中,华北落叶松林群丛的多样性指标最高,林下植被丰富度相对较高且不同地域的群丛差异性较小。【结论】百花山自然保护区内植物多样性丰富,不同植被群系间物种多样性差异明显,海拔是影响保护区植被群系物种组成和分布的重要因素。
【Objective】To study the structure and composition of vegetation alliances and the characteristics of biodiversity in the Beijing Baihuashan National Nature Reserve.【Method】This paper took the forest,shrub and meadow alliances as the research subjects.Representative alliances were selected to set up quadrats.According to the principles of systematic and representative,25 forest community quadrats(including Quercus mongolica forest,Larix gmelinii var.principis-rupprechtii forest,Juglans mandshurica forest,Pinus tabuliformis forest,and Betula platyphylla forest),10 shrub quadrats(including Lespedeza bicolor and Spiraea salicifolia,etc.),and 30 meadow quadrats(including Deyeuxia pyramidalis and Sanguisorba officinalis etc.)were laid out for field investigation.The composition,structure and biodiversity characteristics of the communities were surveyed and analyzed.【Result】The results showed that among herbaceous plants,the genus Carex has the widest distribution;among shrubs,Spiraea,Leptopus chinensis,and Lespedeza are dominant species and are the main components of the vegetation in the area;among the arboreal associations,Larix gmelinii association has the highest diversity index,the richness of the understory vegetation is relatively high,and the differences between alliances in different regions are relatively small.【Conclusion】It is rich in plant diversity in the Beijing Baihuashan National Nature Reserve,and the species diversity among different vegetation communities varies significantly.Altitude is an important factor influencing the species composition and distribution of vegetation communities in the reserve.
