摘要

[目的] 分析刺槐在黄土丘陵区不同立地条件下的适应机制及适应成本，为该区的植被恢复提供理论依据。[方法] 采用野外调查方法，对黄土高原丘陵区不同坡向和坡位的刺槐群落功能性状、生长状况差异进行研究，分析影响刺槐生长的主要因素。[结果] ①阳坡刺槐的叶氮含量、叶磷含量、叶有机碳含量、根磷含量、根有机碳含量、根组织密度均大于阴坡；根氮含量、叶厚度、叶组织密度、比叶面积、比根长均小于阴坡。随坡位上升，叶氮含量、叶磷含量、叶有机碳含量、根磷含量、根氮含量、比叶面积、叶厚度均呈减小趋势；根有机碳含量和叶组织密度呈增大趋势。②刺槐功能性状与环境因子间响应关系显著；性状间的协变和权衡关系在同一器官和不同器官间均存在。③刺槐的株高、胸径、地径、冠幅均表现为阳坡大于阴坡，且随坡位升高而显著减小；其生长状况与功能性状间关系显著。[结论] 刺槐在阳坡和下坡位适应成本较低，能够发挥相对大的生态效益。

Abstract

[Objective] The adaptation mechanism and cost of Robinia pseudoacacia under different site conditions in the loess hilly and gully area of the Loess Plateau were studied to provide support for vegetation restoration in this area.[Methods] By investigating the variations in the functional traits and growth performance of R. pseudoacacia at sites with different slope aspects and positions

we analyzed the main factors affecting the growth of R. pseudoacacia in a heterogeneous environment in the loess hilly and gully area.[Results] ① The leaf nitrogen content

leaf phosphorus content

leaf organic carbon content

root phosphorus content

root organic carbon content

and root tissue density of R. pseudoacacia were higher on sunny slopes than on shady slopes. With a change in the position of the slope from a lower to a higher position

the leaf nitrogen content

leaf phosphorus content

leaf organic carbon content

root phosphorus content

root nitrogen content

specific leaf area

and leaf thickness decreased

while the root organic carbon content and leaf tissue density increased; ② Significant relationships were found between the functional traits of R. pseudoacacia and environmental factors

with the soil factors exerting the most influence. A trade-off between functional traits has been found

not only within the same organ

but also among different organs; ③ The plant height

diameter at breast height (DBH)

ground diameter

and crown width of R. pseudoacacia was larger on sunny slopes than on shady slopes and decreased significantly with a change in the slope position from lower to higher. Meanwhile

a significant relationship was also found between the growth and functional traits of R. pseudoacacia.[Conclusion] On sites at lower positions with a south-facing aspect

R. pseudoacacia has a lower adaptation cost and can bring about greater ecological benefits.
