摘要

摘要本研究旨在确定并分析巴西东南部圣州(Espírito Santo State) o Mateus河流域原生林破碎片的景观生态指标。碎片分为四个大小类，称为C1(50公顷)。指标根据其性质分为(i)面积和密度，(ii)边缘，(iii)形状，(iv)中心区域和(v)邻近度。共发现原生林残片4286片，占流域总面积的7.80%。碎片的形状较为规则，较小(<25.10 ha)，因此具有较大的边缘效应。研究结果表明，研究的流域高度破碎化，因此需要制定森林保护和恢复退化森林的战略。

Forest cover analysis of a highly fragmented basin in northern Espírito Santo State, Brazil

analysis Abstract This study aimed to determine and analyze landscape ecology metrics to characterize the spatial pattern of fragments of native forest in São Mateus River basin, Espírito Santo State, Southeastern Brazil. Fragments were divided into four size classes called C1 (<5 ha), C2 (5-25 ha), C3 (25.10-50 ha) and C4 (>50 ha). Metrics were grouped according to their nature in (i) area and density, (ii) edge, (iii) shape, (iv) central area and (v) proximity. In total, 4,286 native forest fragments were identified, which represented 7.80% of total area of the basin. There is a predominance of fragments with more regular shapes, small (<25.10 ha) and, consequently, with greater edge effect. Results showed that the drainage basin studied is highly fragmented, which reinforces the need for strategies aimed at forest conservation and restoration of degraded forests in this region.

期刊介绍： Scientia Forestalis is a scientific publication of the IPEF – Institute of Forest Research and Studies, founded in 1968, as a nonprofit institution, in agreement with the LCF – Department of Forest Sciences of the ESALQ – Luiz de Queiroz College of Agriculture of the USP – São Paulo University. Scientia Forestalis, affiliated to the ABEC – Brazilian Association of Scientific Publishers, publishes four issues per year of original papers related to the several fields of the Forest Sciences. The Editorial Board is composed by the Editor, the Scientific Editors (evaluating the manuscript), and the Associated Editors (helping on the decision of acceptation or not of the manuscript, analyzed by the Peer-Reviewers.
