生态入侵及其对植被生态系统服务功能的影响研究

在生态入侵的概念、入侵途径、影响入侵的因素和对植被生态系统服务功能的影响等几方面进行了阐述，入侵种通过自然途径或人为途径进入本地生态系统，造成对当地植被生态系统服务功能的影响，这种入侵受多方面因素的影响，包括内因和外因，内因主要是物种本身的各种特有性质，如繁殖力，抗逆性，适应性，外因有自然环境因素和社会环境因素之分，另外，一些全球变化如温室效应，臭氧空洞，酸雨等，对生态入侵也会产生影响，生态入侵对植被生态系统服务功能的影响是多方面的，对它的预防和控制需要进一步的研究。

Ecological Invasion and Impact on the Ecosystem Services of Vegetation

The idea of ecological invasion,the pathways of invasion,the factor influencing invasion and the impact of invasion on the ecosystem services of vegetation are mentioned. Exotic species enter a new ecosystem with or without human facilitating,and then establish in the ecosystem. The invasion can influence ecosystem service. The process is affected by the internal and external factors. The internal are from the species themselves,including reproduction effort,anti adversity and adaptation,and the external are from the natural environment and the social environment. In addition,some other global problems are also relevant to ecological invasion,including global warming,depletion of ozone and acid rain. Ecosystem service is affected by ecological invasion in various aspects,and the ways of prevention and control need more study.
