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
