摘要: 试验研究了河北雾灵山5种人工纯林(油松、蒙古栎、核桃楸、华北落叶松和白桦)的灌草多样性及其生物多样性与影响因子的关系.结果表明:5种林分中的灌木和草本的Menhinick丰富度指数分别为0.41~0.76,0.77~2.12;Simpson多样性指数分别为0.41~0.78,0.64~0.97;Shannon-Wiener多样性指数分别为0.87~2.13,0.99~2.71;均匀度指数分别为0.49~1.10,0.51~1.00.物种多样性受外界环境因子的影响较大,随海拔升高灌木多样性减小,草本多样性指数先增大后减小;随坡度增大灌木和草本多样性增大;随林龄增大草本多样性减小;随郁闭度增大灌木多样性减小.
英文摘要: This paper studied the shrub and herbaceous plant diversity and species diversities' influence factors of five different artificial pure forests(Pinus tabulaeformis,Quecus momgolica,Juglans mandshurica,Larix principic-rupprechti,Betula platyphylla)in Wuling Mountain,Hebei province.The results showed that:shrubs and herbal's Menhinick richness index was 0.41~0.76and 0.77~2.12,respectively;their Simpson diversity index values was 0.41~ 0.78and 0.64~0.97,respectively;their Shannon-wiener diversity index were 0...
