南方红壤侵蚀区不同恢复阶段下马尾松叶经济型谱特征
Characteristics of Leaf Economic Phenotypes of Pinus massoniana under Different Stages of Restoration in the Red Soil Erosion Area of Southern China
摘要
Abstract
In the process of ecological restoration,plants form a trade-off strategy between resource acquisition and resource conservation in order to adapt to changes in the environment.The proposal of leaf economic phenotypes provides a theoretical basis for quantifying and describing the resource trade-off strategies of plants.In this paper,we took the leaf traits of Pinus massoniana under different stages of restoration in the southern red soil erosion area as the research object,and explored the changing law of leaf traits(specific leaf area,leaf dry matter content,leaf relative water content,leaf total carbon content,leaf total nitrogen content,and leaf total phosphorus content)of P.massoniana in the process of ecological restoration,as well as the correlation between the leaf traits and the differences between the leaf traits under different stages of restoration.The results showed that specific leaf area,leaf total nitrogen content and leaf total phosphorus content gradually increased with the progress of recovery;leaf total carbon content was significantly negatively correlated with leaf total nitrogen content and leaf total phosphorus content;and the PCA1 axis scores of leaf traits increased as the recovery progressed.The results indicated that the combination of leaf traits in P.massoniana changed from nutrient-conserving traits to nutrient-acquiring traits with the recovery stage.关键词
