- Abstract:
- [Objective] The aims of this study are to explore the growth adaptation strategies of different life-types of plants to the habitats in the Yanhe River Basin, and to provide theoretical basis and practical guidance for understanding the mechanisms of plant adaptation to the environment and the selection of species for vegetation restoration in this basin. [Methods] Using the Yanhe River Basin in the Loess Hills region as the study area, we selected three plant life types: trees, shrubs and herbs, six plant functional traits related to resource acquisition capacity were investigated. ANOVA, linear regression and redundancy analysis were applied to investigate the adaptation strategies and mechanisms of different life types of plants to the environment in the Yanhe River Basin. [Results] The specific leaf area, specific root length, leaf tissue density, root tissue density, leaf nitrogen content, and root nitrogen content of different life types of plants in the Yanhe River Basin were significantly different. Water was the limiting factor for plant survival in the Yanhe River Basin. [Conclusion] To adapt to the habitats of the Yanhe River basin, herbaceous plants adopted a ‘fast investment-gain' type(acquisition type)strategy, while shrubs and trees adopted a ‘slow investment-gain' type(conservative type)strategy.
