Exploration of Factors Influencing Nutrient Reabsorption in Forest Leaves
Nutrient resorption(NR)in forest leaves refers to the process by which forests resorb some nutrients from senescent leaves and transfer them to mature leaves or other organs and tissues.Crucial to the nutrient cycling of forests,nutrient resorption in forest leaves can reflect the nutrient utilization efficiency of forests,thus enabling them to adapt to seasonal and environmental changes,so it is an important nutrient conservation strategy for forests.The utilization and preservation strategies of nutrients by trees are key to forest management.There is an important intersection and correlation between forest management and forest cultivation.Studying the influencing factors of nutrient resorption in forest leaves can help reveal forests'adaptation strategies to seasons and environments,and solve the problem of which cultivation methods and tools should be the focus for different forest types,growth stages,habitats and climates.And it can provide planning basis for targeted forest management strategies.Therefore,this paper comprehensively summarized the effects of different growth stages,growth environment,nutrient addition,leaf functional traits and ecological stoichiometric ratio on nutrient resorption of forest trees,and prospected the establishment of influencing factors system of nutrient resorption of forest leaves in the future,in order to provide theoretical basis for fine cultivation of forest trees and precise management of forestry.
