The spatial shifts and vulnerability assessments of ecological niches for trees will offer fresh perspectives for sustainable development and preservation of forests, particularly within the framework of rapid climate change. is a fast-growing native timber plantation species in China, but the natural resources have been severely damaged. Here, a comprehensive habitat suitability model (including ten niche-based GIS modeling algorithms) was developed that integrates three types of environmental factors, namely, climatic, soil, and ultraviolet variables, to assess the species contemporary and future distribution of suitable habitats across China. Our results suggest that the habitats of generally occur in subtropical areas (about 1.52 × 10 km). However, the growth of is profoundly shaped by the nuances of its local environment, the most reasonable niche spaces are only 1.15 × 10 km when limiting ecological factors (soil and ultraviolet) are considered, generally considered as the core production region. Furthermore, it is anticipated that species-suitable habitats will decrease by 10 and 8% with climate change in the 2050s and 2070s, respectively. Our study provided a clear understanding of species-suitable habitat distribution and identified the reasons why other niche spaces are unsuitable in the future, which can warn against artificial cultivation and conservation planning.
树木生态位的空间转移和脆弱性评估将为森林的可持续发展和保护提供新的视角，特别是在快速气候变化的框架内。在中国是一种快速生长的本土人工林树种，但自然资源已遭到严重破坏。在此，开发了一个综合栖息地适宜性模型（包括十种基于生态位的地理信息系统建模算法），该模型整合了气候、土壤和紫外线变量这三种环境因素，以评估该物种在中国当代和未来适宜栖息地的分布。我们的结果表明，的栖息地一般出现在亚热带地区（约1.52×10平方千米）。然而，的生长受到当地环境细微差别的深刻影响，当考虑限制生态因素（土壤和紫外线）时，最合理的生态位空间仅为1.15×10平方千米，该区域通常被视为核心产区。此外，预计在2050年代和2070年代，随着气候变化，适宜该物种的栖息地将分别减少10%和8%。我们的研究清晰地了解了物种适宜栖息地的分布，并确定了未来其他生态位空间不合适的原因，这可为人工种植和保护规划提供警示。
