Characteristics of Understory Plant Diversity in Artificial Mixed Eucalyptus Forests
[Objective]To understand the composition and diversity characteristics of understory plants in different artificial mixed Eucalyptus forests at Huangsha Forest Farm in Zijin County.[Method]Three types of Eucalyptus artificial mixed forests, namely Eucalyptus camphor mixed forest (Ⅰ), Eucalyptus fir mixed forest (Ⅱ), and Eucalyptus masson pine mixed forest (Ⅲ), were selected as the research objects to explore the relationship between tree species composition and understory plant diversity in Eucalyptus artificial forests.[Result]The results showed that there were a total of 51 species of 35 families, 50 genera, and 15 families, 19 genera, and 20 species of shrubs in the understory of the three artificial forests, with the main species being Rubus alceifolius, Maesa japonica, Melastoma candidum;there are 24 species of herbaceous plants in 24 genera and 15 families, with the majority being Dicranopteris dichotoma,Melastoma candidum, Blechnum orientale and Arathelyp-teris glanduligera;there are 7 species, 7 genera, and 6 families of vine plants, with Pueraria montana, Lygodium japonicum and Sabia japoni-ca being more widely distributed.The Simpson dominance index and Shannon diversity index of species in the shrub layer, herbaceous layer, and vine layer are all highest in the Eucalyptus-Cinnamomum camphora mixed forest (Ⅰ) and lowest in the Eucalyptus-Pinus massoniana mixed forest (Ⅲ).[Conclusion]Creating a mixed Eucalyptus-Cinnamomum camphora forest is more conducive to promoting stand growth and impro-ving understory plant diversity.When formulating measures to improve the quality of Eucalyptus stands, attention should be paid to the rela-tionship between understory plant diversity and tree species composition in artificial forests under management measures.
