| 摘 要： | 外来植物的引种和入侵已成为一个全球性的重要问题.许多外来植物不仅可以改变陆地生态系统的氮输入、输出,而且还可以通过改变氮素吸收、再利用,凋落物质量,土壤环境,土壤生物等因子影响陆地生态系统内都氮循环.在概述陆地生态系统氮循环基础上,系统综述了外来植物对陆地生态系统氮循环的影响方式和途径以及可能造成的生态后果,并对将来研究方向进行了展望:应更多考虑外来植物影响机制的复杂性、不同养分元素循环的相互作用和新技术手段的应用.

| Abstract: | Introduction and invasion of exotic plants are important global issues.Exotic plants can not only change the input and output of nitrogen,but also affect the nitrogen flows within terrestrial ecosystem through altering absorption and reuse of nitrogen,litter quality,soil microcosm and soil biota.Based on terrestrial nitrogen cycling framework,we reviewed the pathways and consequences that exotic plants affect terrestrial nitrogen cycling.Complexity of mechanisms,interaction of different nutrient cycling,and... |
