摘要

蕨类植物或蕨类植物是隐花科的低等植物,可以区分根、叶和茎。蕨类具有重要的生态意义,即作为林下植物,通过混合土壤凋落物对森林生态系统的长期可持续性做出贡献,作为地被植被,作为食物链中的生产者,以及作为森林生态系统演替中的先驱植物之一。本研究旨在确定北苏门答腊岛Sibolangit地区Bukum村林区不同植被下蕨类植物的种类、多样性指数和分布格局。本研究采用的方法是探索性调查法,采用目的性抽样技术。结果表明:布库姆村林区有39种,流域植被有21种,咖啡园植被有16种,原始林植被有14种。流域植被多样性指数为2.32,咖啡人工林为2.02,原始林为1.86。多样性指数结果表明,布库姆村林区蕨类植物多样性为中等,群落较为稳定。河流植被的Morisita指数为1.43,咖啡园植被为2.13,原始林植被为2.05。各植被的Morisita指数结果表明,由于蕨类植物生长所需的环境条件不均匀,Bukum村林区蕨类植物的分布格局是分组的。

DIVERSITY OF FERNS (PTERIDOPHYTA) WITH DIFFERENT VEGETATION IN FOREST AREAS BUKUM VILLAGE, SIBOLANGIT SUB-DISTRICT
Ferns or Pteridophyta are lower plants from the Cryptogamae division, which can be distinguished between roots, leaves, and stems. Ferns have great ecological importance, namely as understory plants that contribute to the long-term sustainability of forest ecosystems by mixing soil litter, as ground cover vegetation, as producers in the food chain, and as one of the pioneer plants in the succession of forest ecosystems. This study aims to determine the species, diversity index, and distribution pattern of ferns based on different vegetation in the Forest Area of Bukum Village, Sibolangit District, North Sumatra. The method used in this research is an exploratory survey method with a purposive sampling technique. The results of this study were 39 species found in the Forest Area of Bukum Village, 21 species in the watershed vegetation, 16 species in the Coffee Garden vegetation, and 14 species in the Primary Forest vegetation. The diversity index in the watershed vegetation is 2.32, the coffee plantation is 2.02, and the primary forest is 1.86. Based on the results of the diversity index, it shows that the diversity of ferns in the Forest area of Bukum Village is classified as moderate so the community is said to be stable. The Morisita index on the river flow vegetation is 1.43, the coffee garden vegetation is 2.13, and the primary forest vegetation is 2.05. The results of the Morisita index from each vegetation indicate that the distribution pattern of ferns in the Forest Area of Bukum Village is grouped because the environmental conditions required by ferns are not uniform.
