[目的]对我国东江流域河岸带外来入侵植物进行调查分析,并对其进行风险评估。[方法]野外调查主要采用样方调查与线路调查相结合的方法,覆盖整个东江流域。其中干流共设52个样点,支流87个样点,累计设置样方624个;风险评估采用多指标综合评价法,设立了6个一级指标,25个二级指标。[结果]经过近2年对东江流域河岸带外来入侵植物进行的详细调查,该流域共发现外来入侵植物51种,隶属于17科38属。对这51种外来入侵植物进行了风险级别评价,结果表明,藿香蓟等18种入侵植物风险评估得分在60分以上,属于高风险级别;土荆芥等26种入侵植物风险评估得分在30～60之间,属于中风险级别;毛花雀稗等7种入侵植物风险评估得分在30分以下,属于低风险级别。[结论]为我国东江流域河岸带的保护和管理以及该流域水环境的治理和功能区划提供了基础资料。

[Objective] The aim was to conduct investigation and risk assessment of the alien invasive plants in riparian zone of Dongjiang River.[Method] The field survey was carried out by the combination methods of sampling plots investigation and route survey,and the whole Dongjiang River was covered.52 sampling points were set in the main streams,and 87 sampling points in tributaries streams,624 quadrats were set in total;multi-index comprehensive evaluation method was adopted for the risk assessment with 6 first-level indexes and 25 second-level indexes.[Result] Through the investigation on the riparian zone of Dongjiang River for 2 years,51 species of alien invasive plants were found,belonging to 17 families and 38 genera.The risk level assessment results of these 51 species showed that 18 species,such as Ageratum conyzoides,belonged to high-level risk with over 60 points;26 species,such as Chenopodium ambrosioides,were between 30 and 60 points which belonged to middle-level risk;7 species,such as Paspalum dilatatum,with less than 30 points belonged to low-level risk.[Conclusion] Basic data on the protection,water environmental management and functional zoning of riparian zone of Dongjiang River were provided.
