Article Synopsis
- The study analyzed the species composition and community structure of a secondary forest in the Qinling Mountains, finding 3162 individual woody plants across 42 species, dominated by temperate tree species.
- Key tree species held a significant importance value, accounting for 64.7% of the community, while the average diameter at breast height (DBH) of all woody plants was 7.58 cm.
- The community structure showed stability but poor renewal, with biodiversity indices lower than subtropical evergreen forests and notable correlations between species distribution and environmental factors like soil and altitude.

To explore the spatial distribution and intraspecific correlation of var. , a domi-nant tree species in a 25 hm plot of warm temperate deciduous broadleaved forest in Qinling Mountains, the pair-correlation function () was used to study the spatial pattern and intraspecific association. The results showed that the diameter class structure of .

- - The study analyzed the distribution of dominant shrub varieties in Qinling Huangguan Plot, finding a pyramid-shaped diameter class structure with the most individuals in the small-diameter class, indicating good renewal and stable growth.
- - Spatial patterns among individuals were primarily aggregated but tended to random distribution as the research scale increased, with various spatial models applied to assess these patterns.
- - Intraspecific relationships showed positive correlations among diameter classes but also some lack of correlation, while interspecific relationships were complex, with a predominance of negative associations and no associations.
Shrub is an important part of forest ecosystem. Exploring the species composition, structure and spatial distribution of shrub layer can lay an important foundation for further clarifying the mechanisms underlying species coexistence, biodiversity maintenance and community succession. In this study, species composition, spatial distribution, and species diversity of shrub layer were analyzed in 25 hm of Huangguan forest plot.

While the China Forest Biodiversity Monitoring Network (CForBio) have basically covered most of the climate regions in China, few plots were located in the climate transition zone. Following the field protocol of CForBio and the Center for Tropical Forest Science (CTFS), a 25 hm(500 m×500 m) forest plot was established in Huangguan Nature Reserve in Shaanxi Province, China, in 2019.

The objective of this study was to analyze the dynamic characteristics of seed rain on abandoned slopes in the hilly-gullied Loess Plateau region and identify the relationship between seed rain and standing vegetation. Three abandoned slopes were chosen as sampling sites in Zhifanggou watershed. Thirty traps were installed at each site to collect seed rain from October 2010 to April 2013.
