摘要:

利用固沙灌木的空间点格局不仅可以揭示物种的生物学特性、种内与种间关系以及环境因素对物种空间分布的影响机制,而且可以预测种群的发展趋势,为植被重建提供参考依据。当前针对沙漠生态系统,特别是中国北方沙区固沙灌木空间点格局的分布特征和规律,还缺乏系统的分析和总结,相关研究缺乏。以中国北方沙区固沙灌木为研究对象,对固沙灌木的种类、生物学特性、生态学功能进行了概述,综述了空间点格局研究中的相关统计量和零模型等重要概念,详细阐述了中国北方沙区不同类型固沙灌木的空间点格局分布特征、规律、灌木间的空间关联性及其影响因素。系统阐述我国北方沙区固沙灌木的空间点格局分布特征和关系,对于系统认识不同尺度上不同固沙灌木的种内和种间关系、在生态系统水平上提出适合中国北方沙区生态系统管理的有效途径具有重要的科学支撑意义。

Abstract:

The spatial point pattern of sand-fixing shrubs not only reveals the biological characteristics of species, intraspecific and interspecific relationships, and the influence mechanisms of environmental factors on species distribution, but also predicts population development trends, providing a reference basis for vegetation restoration. Current research on desert ecosystems, particularly regarding the distribution characteristics and patterns of spatial point patterns of sand-fixing shrubs in northern China's sandy regions, lacks systematic analysis and comprehensive summarization, with relatively limited studies available. Focusing on sand-fixing shrubs in northern China's sandy regions, this study provides an overview of their species composition, biological characteristics, and ecological functions. It reviews key concepts in spatial point pattern analysis, including relevant statistical metrics and null models, and elaborates in detail on the distribution characteristics, patterns, spatial associations among shrubs, and influencing factors of different types of sand-fixing shrubs in these regions. By systematically summarizing the spatial point pattern distribution features and relationships of sand-fixing shrubs in northern China's sandy regions, this research contributes to a comprehensive understanding of intraspecific and interspecific relationships across different scales. Furthermore, it holds significant scientific value for proposing effective ecosystem management strategies tailored to the ecological conditions of northern China's sandy regions at the ecosystem level.

Key words: desert ecosystem, sandy regions of northern China, sand-fixing shrubs, spatial point pattern
