Abstract:

Aims Shrublands are widely distributed in the North China. Understanding species composition and community assembly of the shrublands has important implications for promoting vegetation restoration in this area. Community phylogenetic structure can reflect community assembly process. In the present study, we explored the distribution patterns, species composition and phylogenetic structure of major shrubland types from North China, and then analyzed the effects of temperature and precipitation on these patterns with the help of the WorldClim dataset.
Methods A total 2 331 plots were setup to survey species composition and phylogenetic structure of major shrubland types in North China. A multiple stepwise regression was used to determine the effects of climatic factors on community phylogenetic structure, and a generalize linear model was used to test the interaction of environmental factors and formation types or vegetation types.
Important findings A total of 570 woody species belonging to 207 genera from 75 families, together with 1 221 herb species belonging to 491 genera from 99 families were recorded during the investigation. Five vegetation types and 195 formation types were identified, and the major formation types were Ostryopsis davidiana formation, Vitex negundo var. heterophylla, Vitex negundo var. heterophylla + Hippophae rhamnoides and Hippophae rhamnoides formation. The species richness of herb layer was higher than that of shrub layer. The phylogenetic structure was over-dispersed for herb layer and was convergent for shrub layer. The phylogenetic structure differed remarkable among different vegetation types. The phylogenetic structures of both shrub and herb layers were significantly correlated with climatic factors, and the interaction of climate factors and vegetation types or formation types as well. Our results indicates that large scale variation of climatic factors regulate community phylogenetic structure of different layers in shrub community, and the effects depend on vegetation types and formation types.
