摘要
近年来,氮沉降和外来植物入侵及其交互的生态环境效应和机制已成为全球环境变化的研究热点问题之一,主要源于两者交互对本地生态系统结构及其功能产生了诸多负面影响。基于氮沉降和植物入侵两大生态环境问题,以氮沉降背景下入侵植物及本地植物之间的地上竞争、地下竞争、土壤理化性质及化感效应变化情况为切入点,并综合分析现已有的研究成果,进而综述并阐明氮沉降背景下入侵植物对本地生态系统的影响及其机制的变化趋势。此外,针对现已有的研究基础、研究局限和后续研究等问题,提出几点后续研究展望。
In recent years,nitrogen deposition and alien plant invasion as well as their interactive eco-environmental effects and the corresponding mechanisms have become one of the research hotspots of global environmental change,mainly due to the multiply negative effects of the interaction between the two environment factors on local ecosystem structure and function.Based on the two ecological problems of nitrogen deposition and plant invasion,this study aims to analyze the current research results in a comprehensive way,so as to summarize and clarify the effects of invasive alien plants on local ecosystems and the trend of the corresponding mechanisms under nitrogen deposition viewed from the following aspects:above-ground competition and underground competition between alien invasive plants and local plant species,soil physicochemical properties,and allelopathic effects of alien invasive plants on local plant species.In addition,based on the existing researches and their limitations,as well as follow-up researches,the author puts forward some follow-up research prospects.
