    基于生态保护格局的长白山北部森林景观特征分析

    Analysis of landscape characteristics of forests in northern Changbai Mountains based on ecological protection pattern.

    • 摘要: 本研究旨在分析长白山林区北部景观格局特征,并以此作为未来生物多样性保护与构建长白山地区整体森林保护格局的依据。基于泉阳和露水河林业局森林资源二类调查资料和林相图,利用Arcgis和Fragstats等软件,从土地利用类型、优势树种和龄组的角度,分析了景观构成要素和森林保护现状,在景观水平和斑块水平上分析了该区景观格局指数特征。结果表明:有林地主导着土地利用类型,森林景观优势明显,研究区整体景观存在破碎化,优势景观类型破碎化程度比较严重;森林景观中各优势树种和龄组景观的优势度较弱,景观连通性较差,树种与林龄结构复杂,景观破碎化更为严重;幼龄林是破碎化最严重的龄组。人为活动对优势树种和林龄组成有着显著的影响,人为干扰是景观破碎化的最主要原因。根据分析结果,该区应科学规划城镇化建设,引导作物栽培合理开展,改善景观破碎化现状并建立有效的生态廊道,提高森林生态系统的生物多样性和稳定性。

       

      Abstract: This study aims to analyze the landscape pattern of Quanyang and Lushuihe forestry bureaus in northern Changbai Mountains, and thus provide basis for future biodiversity conservation and construction of overall forest protection in Changbai Mountains. Based on the forest resources inventories and forest type maps, we analyzed the landscape elements and forest protection situation by using spatial analysis software Arcgis and Fragstats. The forest structure and landscape pattern were studied in terms of land-use type, dominant tree species and age group. Combined with overlay analysis of forest type map and landscape situation, suggestions on management of each planning area are proposed. The results showed that forest is the dominated land use type, showing apparent superiority in forest landscape; however, fragmentation exists in the overall landscape in the study area, and fragmentation is more serious in the dominant landscape. The dominance of landscape of dominant tree species and age group is weak, the landscape connectivity is poor, tree species and age composition are complex, and the landscape fragmentation is more serious. The young growth forest is subjected to the most serious fragmentation. Human activities have significant effects on the dominant tree species and age composition, and human disturbance is the major reason causing landscape fragmentation. Based on the forest landscape classification and spatial pattern analysis, according to the current status of landscape and the objectives of forest landscape planning, we propose methods of landscape planning at different scales in this area. We suggest that the ideal forest landscape should include natural forest protection area, artificial tending area, Korean pine seed orchard protection areas and ecological corridors. To sum up, managers should make greater efforts in tending Korean pine seedlings, replanting bare land, restoring degraded forest, improving the status of landscape fragmentation and establishing ecological corridors. All these measures have important implications for responding to climate change and improving the biological diversity and stability of forest ecosystem.
