摘要
采用生态化学计量学理论可以探究森林生态系统中养分的平衡和循环特性.化学计量比具有一种动态平衡的特性,但人为因素的干扰可能会在不同程度上改变森林生态系统各组成部分的化学计量特征.施肥作为一种迅速而有效的林业管理手段,研究其对林地化学计量特征的影响,对于提高肥料的利用效率具有重要意义.综合林地施肥的相关研究,总结施肥对林木、凋落物及土壤化学计量特征的影响,旨在为林地施肥实践提供指导和参考.
Abstract
Utilizing the theory of ecological stoichiometry enables the exploration of nutrient balance and cycling characteristics within forest ecosystems.The stoichiometric ratios has a characteristic of dynamic equilibrium,however the interference of human factors may change the stoichiometric characteristics of each components of the forest ecosystem to varying degrees.Fertilization,as a rapid and effective means of forestry management,it is of significance to study the effect of fertilization on the stoichiometric characteristics of forest land for improving the utilization efficiency of fertilizer.This article synthesizes relevant research on forest land fertilization,and summarizes the effects of fertilization on the stoichiometric characteristics of trees,litter,and soil,with the aim of providing guidance and reference for the practice of forest land fertilization.
