基于天然更新性能筛选海南岛木麻黄海防林混交树种

Selection of mixed species of Casuarina equisetifolia L. based on natural regeneration properties

  • 摘要: 基于对海南木麻黄(Casuarina equisetifolia L.)海防林天然更新情况的实地调查,采用更新数量、更新分布范围和更新结构3项单目标评价方法和熵权综合评价方法,对不同树种在木麻黄林下的天然更新性能进行评价和排序,据此筛选出适宜在木麻黄林下天然更新的树种。结果显示,更新能力较强的树种有:乔木树种潺槁木姜子(Litsea glutinosa(Lour.) C.B.Rob.)、大叶相思(Acacia auriculiformis A.Cunn.ex Benth)、苦楝(Melia azedarace L.)和鹊肾树(Streblus asper Lour.);小乔木鸦胆子(Brucea javanica(Linn.) Merr.)、露兜树(Pandanus tectorius Sol.)和暗罗(Polyalthia suberosa(Roxb.) Thw.);灌木酒饼簕(Atalantia buxifolia(Poir.) Oliv.)、调料九里香(Murraya koenigii(L.) Spreng.)、刺篱木(Flacourtia indica(Burm.F.) Merr.)和基及树(Carmona microphylla(lam.) G.Don)。具有一定更新潜力的树种有:乔木树种榄仁树(Terminalia catappa L.)、红厚壳(Calophyllum inophyllum L.)等;小乔木粗糠柴(Mallotus philippensis(Lam.) Muell.Arg.)、八脉臭黄荆(Premna octonervia Merr.et Metc.)等;灌木苦郎树(Clerodendrum inerme(L.) Gaertn.)、九节(Psychotria rubra(Lour.) Poir.)等。小乔木和灌木是海防林的伴生树种,适当保留和种植可提高木麻黄林的物种多样性和层次结构。选用天然更新良好的树种与木麻黄混交,最终可实现海防林由人工林向“近自然”林的转化。

     

    Abstract: Based on a field survey of natural regeneration condition in Hainan Casuarina equisetifolia L. coastal protection forest, single objective evaluation methods, respectively taking regeneration quantity, regeneration distribution range and regeneration structure as an evaluation index, and entropy weight comprehensive evaluation method were adopted to evaluate and sort the natural regeneration performance of different tree species under Casuarina equisetifolia forests. Based on the evaluation result, the tree species suitable for natural regeneration under the Casuarina equisetifolia forests were selected. Results showed that tree species with good regeneration ability were Litsea glutinosa (Lour.) C. B. Rob., Acacia auriculiformis A. Cunn. ex Benth, Melia azedarace L., Streblus asper Lour. The small trees are Brucea javanica (L.) Merr., Pandanus tectorius Sol., Polyalthia suberosa (Roxb.) Thw. Shrubs are Atalantia buxifolia (Poir.) Oliv., Murraya koenigii (L.) Spreng., Flacourtia indica (Burm. F.) Merr., and Carmona microphylla (lam.) G. Don. Species with certain regeneration potential included tree species Terminalia catappa L., and Calophyllum inophyllum L.; small trees Mallotus philippensis (Lam.) Muell. Arg. and Premna octonervia Merr. et Metc., and shrubs Clerodendrum inerme (L.) Gaertn. and Psychotria rubra (Lour.) Poir. Small trees and shrubs were the associated species of the coastal protection forests; therefore, proper conservation and planting of these associated tree species should improve species diversity and hierarchy of Casuarina equisetifolia forests. The mixed planting of tree species selected with good natural regeneration in Casuarina equisetifolia forests could help realize the transformation from artificial forest to “near natural” forest.
