Abstract

Mapping tree species diversity and networks enhances the understanding of ecological dynamics and supports effective biodiversity conservation and forest management. In this study, we investigated tree species distribution, richness, beta diversity and ecological centers were analyzed using NFI-7 data surveyed between 2016 and 2020 in South Korea. The coexistence species networks were analyzed using the Jaccard similarity index and ecological hub locations were examined corresponding to NFI grid centers and Korean administrative boundaries. We observed the heterogeneity in tree species distribution. Species Korean red pine (Pinus densiflora) dominated (22.49 %) the Korean forest and Korean mountain cherry (Prunus maximowiczii Rupr) observed as the highly spatially autocorrelated (Moran’s I= 0.327; p < 0.001). Based on the degree of centrality of Jaccard similarity networks, grid (128.005 34.823) had 21 species, Sannae-myeon (87 species), Jeju-si (133 species), and Gyeongsangnam-do (170 species) were observed as the most connected zones compared within NFI grids, sub municipal, municipal, and provincial boundaries, respectively. Our approaches and results provide ecological information about tree species richness, diversity, and network-based priority zones to support biodiversity monitoring, ecological assessments, and sustainable environment management.

揭示树种多样性和生态相似性网络：来自韩国国家森林调查的见解

绘制树种多样性和网络可以增强对生态动态的理解，并支持有效的生物多样性保护和森林管理。利用2016 - 2020年韩国NFI-7调查数据，对树种分布、丰富度、beta多样性和生态中心进行了分析。利用Jaccard相似性指数分析了共存物种网络，并根据NFI网格中心和韩国行政边界确定了生态枢纽位置。我们观察到树种分布的异质性。红松（Pinus densiflora）占主导地位（22.49 %），韩国森林和韩国山樱桃（Prunus maximowiczii Rupr）具有高度的空间自相关（Moran’s I= 0.327; p <； 0.001）。基于Jaccard相似网络的中心性，网格（128.005 34.823）有21种，其中山奈面（87种）、济州（133种）和庆尚南道（170种）是NFI网格内、次市、市和道边界内连接最紧密的区域。我们的方法和结果提供了树种丰富度、多样性和基于网络的优先区域的生态信息，为生物多样性监测、生态评估和可持续环境管理提供支持。

期刊介绍： Global Ecology and Conservation is a peer-reviewed, open-access journal covering all sub-disciplines of ecological and conservation science: from theory to practice, from molecules to ecosystems, from regional to global. The fields covered include: organismal, population, community, and ecosystem ecology; physiological, evolutionary, and behavioral ecology; and conservation science.
