Abstract

This study was to obtain the description of tropical lowland forest of Papua in Sewan village, Sarmi District, Jayapura region. The main objective was to investigate the structure, species composition and ecological value of the forest vegetation. Research methods included line transect, documentation, interview and literature review. Index Shannon Wiener was used to determine the level of species diversity. The results revealed that 27 tree species that grouped into 17 families inhabited the study area. The density of trees was 209 individuals/ha. A number of saplings were identified into 17 species and grouped into 15 families with the density 104 individuals/ha. At the tree level, species with the high important value (IV) index. important value (IV) index were Pometia pinnata Forst. (54.31%), Macaranga gigantea M.A. (45.33%), Knema sp. (27.37%), Nauclea orientalis L. (20.69%), Intsia palembanica Miq. (13.86%), and the other species had lower INP. At the saplings level species that had high INP were Pometia pinnata Forst. (84.05%), Horsfieldia sylvestris Warb. (34.87%), Knema sp (25.92%), Celtis nerifolia (22.54%), and Pterocarpus indicus Willd. (18.12%). Diversity index at tree level and saplings level were 2.73 and 1.91 respectively, and this showed the high diversity of the trees compared to that of the saplings. The ecological value of the forest in Sewan village included the function as watershed area, buffer zone for the wildlife and as habitat for several fauna especially birds and bats. Key words: analysis of vegetation, species of trees, Sewan village, Sarmi.

本研究的目的是获取查亚普拉地区萨尔米区塞万村巴布亚热带低地森林的描述。主要目的是调查森林植被的结构、种类组成和生态价值。研究方法包括样条法、文献法、访谈法和文献法。采用Shannon Wiener指数确定物种多样性水平。结果表明，研究区共有17科27种树种。乔木密度为209株/ha。林分17种，分15科，密度104株/ha。在乔木水平上，重要值(IV)指数高的树种。重要价值(IV)指标为石榴林。(54.31%)、大菱鲆(45.33%)、克奈马(27.37%)、东方核桃仁(20.69%)、古班尼卡(Intsia palembanica Miq.);(13.86%)，其余树种INP均较低。在幼树水平上，INP较高的树种为石榴林。(84.05%)， Horsfieldia sylvestris Warb。分别为34.87%、25.92%、22.54%和Pterocarpus indicus wild。(18.12%)。乔木水平和幼树水平的多样性指数分别为2.73和1.91，表明乔木的多样性高于幼树。Sewan村森林的生态价值包括作为分水岭的功能，野生动物的缓冲区，以及几种动物特别是鸟类和蝙蝠的栖息地。关键词:植被分析，树种，塞湾村，萨尔米。
