摘要
林间草地作为森林和草地两个相邻生态系统的过渡区,具有重要的生态价值。然而,国内外对其认识存在较大差异,且尚未形成普遍接受的概念和分类体系,限制了对林间草地的生态保护和合理利用。为解决这一问题,在综合分析国内外相关研究成果并开展广泛实地调研的基础上,给出了林间草地的科学定义及内涵,即在森林分布区内生长于大面积森林内部或边缘的成片草地,以及与稀疏林木或灌木共生的区域。在充分考虑我国北方林间草地的地理环境特征、可利用性及其在中、高空间分辨率遥感影像中的可辨识性基础上,建立了我国北方林间草地分类体系,包括林窗草地、林缘草地、疏林草地和灌木林草地4个类型及12个亚类。研究结果为我国林间草地的生态保护和可持续利用提供科学支撑。
Inter-silva grasslands,serving as a critical transitional zone between forest and grassland ecosystems or grassland within forest land,have significant ecological importance.However,a widely accepted concept and a unified standard classification framework for inter-silva grasslands is not well recognized,neither domestically nor internationally,and this lack of recognition leads to constraints on their ecological conservation and rational utilization.Based on a comprehensive analysis of the state-of-the-art research findings from around the world along with extensive field surveys in typical forests of northern China,this study proposes a scientific definition of intersilva grasslands.Inter-silva grasslands are defined as grassland patches of varying sizes and forms that occur within or on the edges of large forests,or that are interspersed with sparse trees or shrubs.Considering the geographic environmental features,usability,and visibility derived from medium to high spatial resolution remote sensing imagery,this classification system for northern China’s inter-silva grasslands includes four classes:forest gap grasslands,forest edge grasslands,sparse forest grasslands,and shrub grasslands,with further subdivision into twelve distinct subclasses.This study provides a conceptual framework to support the ecological protection and sustainable use of inter-silva grasslands in northern China.
