摘　　要：通过对紫茎泽兰入侵造成生物群落结构及其多样性变化的资料搜集,分析了紫茎泽兰对入侵生境的植物、动物及微生物的群落结构及物种多样性的影响,并从生物入侵与群落结构、功能、多样性、生态过程等方面的相互作用及相互关联,探讨了外来入侵植物紫茎泽兰对群落的入侵效应。提出了紫茎泽兰对群落的入侵效应是一个考虑多因素及其互相影响、共同作用的生态多样性问题,其对群落的结构和功能存在着多因素交错的影响效应,可通过群落多样性、群落结构与功能的动态变化反映出来。应基于生物系统的整体,多角度、多层次地考虑各因素的相互影响,深入研究外来生物入侵的群落效应和生态过程,才能提出影响外来生物入侵的生态措施。Based on collected data, the effect of weed Ageratina adenophora invasion on community structure and species diversity was analyzed. The research was conducted on bioXogical invasion and community structure and function, community diversity, ecological process, as well as correlations among them. It was a ecological diversity question that considered many factors and their mutual influence and interaction. There were many factors imquen- cing the structure and function of the community in the process of invasion of Ageratina adenophora. Effect of inva- sion on community was reflected through dynamic changes of community diversity, structure and function
