广西国有高峰林场森林景观格局演变OA
Evolution of Forest Landscape Pattern in Guangxi State-owned Gaofeng Forest Farm
为研究城郊大型国有林场森林景观格局动态演变,揭示其变化规律,以广西壮族自治区国有高峰林场为研究对象,基于2009、2014、2019和2024年森林资源调查数据,采用景观类型面积转移矩阵和景观格局指数方法,对森林景观格局进行分析.结果表明,2009-2024年,研究区景观类型均以阔叶纯林、混交林、其他林地和针叶纯林为主,其中阔叶纯林占绝对优势;景观类型转移主要发生在阔叶纯林、混交林和其他林地间,前期主要表现为混交林转移为阔叶纯林,后期主要表现为阔叶纯林转移为混交林和其他林地.研究区景观破碎化程度在2009-2014年趋于下降,斑块呈现整合趋势;2014-2024年,景观破碎化加剧,边缘效应和斑块形状复杂性均持续增强.城郊大型国有林场森林景观未来管理需依据不同空间单元所受的主导政策约束与发展目标,采取差异化空间干预策略,实现生态治理模式升级.
In order to explore dynamic evolution and change rules of forest landscape patterns of large suburban state-owned forest farms,taking Guangxi State-owned Gaofeng Forest Farm as research object,based on forest resource survey data of 2009,2014,2019 and 2024,landscape type area transition matrix and landscape pat-tern indices methods were adopted to analyze forest landscape pattern.Results showed that from 2009 to 2024,landscape types in study area mainly included pure broad-leaved forests,mixed forests,other forest lands and pure coniferous forests,among which pure broad-leaved forests were absolutely dominant.Landscape type con-versions mainly occurred among pure broad-leaved forests,mixed forests and other forest lands.Mixed forests were largely converted into pure broad-leaved forests in early period,while pure broad-leaved forests mainly transformed into mixed forests and other forest lands in late period.Degree of landscape fragmentation in study area showed tendency to decrease from 2009 to 2014,with patches exhibiting trend of consolidation.From 2014 to 2024,landscape fragmentation intensified,accompanied by continuously increasing of edge effect and patch shape complexity.For future forest landscape management of large suburban state-owned forest farms,differen-tiated spatial regulation strategies should be formulated according to leading policy constraints and develop-ment objectives of different spatial units,so as to realize improvement of ecological governance mode.
