中文摘要：

【目的】了解外来植物对广西湿地的入侵情况,为广西湿地保护、管理和利用提供科学依据。【方法】采用文献分析与野外调查相结合的方法,对广西区内的湿地斑块进行系统调查,调查内容包括入侵植物的种类、分布、入侵强度、入侵途径及危害程度。【结果】初步认定广西湿地外来入侵植物有16种,隶属于12科,其中以禾本科最多,有4种,占入侵种总数的25.00%。从来源看,原产美洲的湿地入侵植物最多,达11种,占68.75%。广西湿地外来入侵植物的入侵方式主要通过有意引入,占75.00%。入侵植物生活型除1种为灌木植物外,其余均为草本植物。对广西湿地危害较大的入侵种是空心莲子草、凤眼莲、大薸、钻形紫菀、大米草。【结论】对外来入侵植物应采取物理、化学、生物防治相结合的综合措施,以提高防控效果。

英文摘要：

[Objective]The present study was made to investigate the status of invasive plants in Guangxi wetland in order to provide a scientific basis for their management in wetlands of Guangxi.[Method]Based on literature surveys and field investigations,a systematic study was conducted to investigate different invading varieties,their distribution,invasion level,invasion channel and detrimental extent in Guangxi wetland.[Result]Sixteen species of invasive plants belonging to 12 families have been found to be inhabitant in wetland areas of Guangxi.Amongst them,four species of Gramineae were found to be most abundant（25%） .Eleven species（68.75%） were originally belonged to America.Data showed that those plants were mainly introduced for specific purposes（75%） .Excluding one bush plant species,there were all herbaceous species amongst invasive plants,and the species such as Alternanthera philoxeroides,Eichhornia crassipes,Pistia stratiotes,Aster subulatus and Spartina anglica,caused severe harm to Guangxi wetland.[Conclusion]The adverse effects of invasive species in wetland should be effectively controlled by physical,chemical and biological methods.
