通过对野外调查资料和相关文献资料的分析,共确定东北地区外来入侵植物23科95种. 在综合分析前人建立的外来入侵物种风险评估方法的基础上,结合东北地区外来入侵植物的实际情况,建立东北地区外来入侵植物的风险评估体系. 通过对东北地区外来入侵植物进行风险评估,确定风险等级为A的植物25种,风险等级为B的植物53种,风险等级为C的植物17种. 针对各风险等级的外来入侵植物提出防治对策.
The 95 alien invasive plants of 23 families were identified in Northeast China based on field investigation and reported data. Based on comprehensive analysis of the previous risk assessment methods of alien invasive species, a risk assessment model of alien invasive plants in Northeast China was established. We assess the alien invasive plants in Northeast China using this model, and 25, 53, and 17 species are identified as the species of the risk levels of A, B, and C, respeetively. Some control measures were presented for each risk level.
