Preliminary report on invasive plants in Guangxi wetland
摘要
Abstract
[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, inva-sion level, invasion channel and detrimental extent in Guangxi wetland. [Result]Sixteen species of invasive plants belong-ing 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 herba-ceous species amongst invasive plants, and the species such as Altemanthera philoxeroides, Eichhomia 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.关键词
