摘要
以小五台山国家级自然保护区的12个主要植物群落为研究对象,对小五台山植物景观美景度、环境质量进行评价及配置模式进行研究,结果表明,(1)12个群落物种组成丰富,共140种,分属于34科96属;空间分布较均匀地分布于不同海拔范围,以北坡为主,坡度均在40°以下。(2)各群落美景度分析值(SBE值)按景观类型进行比较:落叶松林>白桦林>红桦林>针阔混交林>白杄+落叶松林>油松林,绣线菊灌丛>胡枝子灌丛>美蔷薇灌丛>虎榛子灌丛,草甸2(海拔位于2 163-2 167m的草甸)>草甸1(海拔位于2 454-2 458m的草甸)。(3)3个针叶林群落的空气离子评议系数均低于1.00,2个阔叶林群落的空气离子评议系数均大于1.00,由此得出阔叶林的空气质量较优。(4)综合以上各项指标,筛选出5种自然植物群落的配置模式,包括红桦林群落、白桦林群落、绣线菊群落、胡枝子群落及草甸2群落。
12 major plant communities in Xiaowutai Mountain Nature Reserve were studied to review the scenic beauty of plants,environmental quality and configuration modes.The results showed that,（1）12 communities were richly composed of 140 species in 96 genera of 34 families,distributed equably at different elevation gradient,mostly in north slope under 40°.（2） The analysis values （SBE value） of each community were compared according to the landscape type： Larix gmelinii forest〉 Betula platyphylla forest〉 Betula albosinensis forest〉mixed forest〉 Picea meyeri＋ Larix gmelinii forest〉 Pinus tabuliformis forest, Spiraea salicifolia brush〉 Lespedeza bicolor brush〉 Rosa bella brush〉 Ostryopsis davidiana brush,Meadow 2 （elevation at 2 163-2 167m） 〉 Meadow 1（elevation at 2 454-2 458m）.（3） Air quality of each community：the air ion evaluation coefficients of 3 coniferous forest communities were lower than 1.00,the air ion evaluation coefficients of two broad-leaved forest communities were greater than 1.00.Therefore,the air quality of broad-leaved forest presented better.Five natural plant community configurations were screened out by the above indexes.
