哥伦比亚阿劳卡市祖拉雷森林的区系和结构研究

1哥伦比亚国立大学，Orinoquia总部。阿劳卡、哥伦比亚。fjmijaress@unal.edu.co。通信作者。摘要本研究的目的是确定在墨西哥阿鲁卡市冲积平原上一个平均高度为1.36 m、直径为2.7 m的森林zural的植物区系和结构组成。本研究的目的是确定在墨西哥恰帕斯州瓜纳华托州的瓜纳华托河流域，在瓜纳华托河流域，在瓜纳华托河流域，在瓜纳华托河流域，在瓜纳华托河流域，在瓜纳华托河流域。在本研究中，我们评估了墨西哥恰帕斯州和恰帕斯州的鸟类种群。由于其直径等级的特征和林地的社会学方面，人们认为这种类型的森林不能用于大规模的木材采伐目的，它提供的生态系统服务可能是受监管的。记录的物种包括:Sarcoglottis acaulis (Sm.)Schltr(兰科)，作为阿劳卡省的新登记;Guapira cf. pubescens (Kunth) Lundell (Nyctaginaceae)和Pouteria cf. stipitata Cronquist (Sapotaceae)是哥伦比亚可能的新记录。关键词:森林，奥里诺科河，大草原，植被，祖鲁。= =地理= =根据美国人口普查，这个县的总面积为，其中土地和(1.)水。= =地理= =根据美国人口普查局的数据，该县的总面积为，其中土地和(1.)水。通过设置10个样带(每个样带50 × 2 m)，我们取样了0.1公顷的地块，以调查所有木本和草本植物物种。= =地理= =根据美国人口普查局的数据，该县的总面积为，其中土地和(1.)水。从树木直径分布和社会学方面等属性来看，祖尔森林似乎不适合商业采伐木材，但它可能提供调节生态系统服务。在有记录的物种中，有三个是值得注意的;无齿肌舌炎(Sm.)Schltr(兰科)，被认为是Arauca系的新记录，Guapira cf. pubescens (Kunth) Lundell (Nyctaginaceae)和Pouteria cf. stipitata Cronquist (Sapotaceae)可能是哥伦比亚植物区系的新记录。

期刊介绍： Colombia Forestal Journal publishes original manuscripts on themes of the forest field and various aspects of natural resources and the environment, which are discriminated in the categories of research article, review, reflection and technical notes of agreement with the stipulations of COLCIENCIAS for scientific publications. According to the classification of scientific areas of the Organization for Economic Cooperation and Development (OECD), Colombia Forestal Journal belongs to the large area of Agricultural Sciences (4), Agriculture, Forestry and Fisheries (4A) and to the discipline Forestry (4A02). Since its creation in 1978, the journal has been edited and published by the Francisco José de Caldas District University with headquarters in Bogotá. The quality of the content of the journal has been strengthened with the collaboration of national and international external evaluators in a double blind arbitration system and the dissemination has been extended by publishing manuscripts in a language different from Spanish and with inclusion in bibliographical databases such as Scopus. , DOAJ, Scielo, Redalyc, Ebsco, CAB Abstracts of CAB International, Forestry Abstracts, Ulrich''s, Latindex, Publindex. Likewise, it has academic profiles at Mendeley, Academia and Researchgate. The articles that are submitted to Colombia Forestal Journal must be original and unpublished and have not been postulated in other journals.
