摘要:
采用踏查与样地调查相结合的方法，系统调查了徐州森林、湿地生态系统外来入侵物种的种类、分布范围、发生和危害现状，评估其入侵风险等级，为外来入侵物种的防范和治理提供参考。结果表明，徐州森林、湿地生态系统外来入侵物种共26科43种，较历史记载的种类（12科17种）有显著增加，其中昆虫5种，占调查总种数11.63%；植物34种，占79.07%；脊椎动物4种，占9.3%。菊科种类最多(13种)，占调查总种数30.23%，较历史记载新增10种；其次是苋科、旋花科，各3种。26种属无意传入，占所有入侵物种的57.14%；13种属人为有意引进，占30.95%；5种属自然传播，占11.91%。33种来自美洲，占外来入侵物种总数量的76.74%；10种来自欧洲、亚洲和非洲，占23.26%。风险分析表明，中风险的外来入侵物种7种，低风险的14种，建议根据其评估的风险等级，采取相应的综合治理方法，防控外来物种的入侵危害。
Abstract:
The species，distribution range，occurrence and hazardous status of invasive alien organisms in forest and wetland ecosystems in Xuzhou were dealt with by personal inspection in combination with sample-plot survey and assess their invasive risk levels，so as to provide references for the prevention and management of alien invasive species.Totally 43 species, 26 families were found.which were evidently increased compared with the previous investigation result (17 species,12 families). Among these species，5 insects（accounting for 11.63% of the total number of species），34 plants（accounting for 79.07% ） and 4 Vertebrates(accounting for 9.3%) were included.Asteraceae had the largest number of species (13 species , accounting for 30.23% ), including 10 new species compared with the historical records，followed by Amaranthaceae and Convolvulaceae，with 3 species each. Twenty-six species were unintentionally introduced(accounting for 57.14%), thirteen species were introduced intentionally(accounting for 30.95%), and 5 species were naturally spread (accounting for 11.91%). Thirty-three species came from the America，accounting for 76.74 % of the total number of invasive alien organisms. Ten species from Europe，Asia and Africa（23.26 %）. Risk analysis showed there were 7 species invasive alien organisms at medium risk , 14 species at low risk.It is suggested that comprehensive measures should be taken to prevent and control the invasive harm of the invasive alien organisms according to the assessed risk level.
