通过对辽宁省沈阳市百鸟公园及其周边0.483 km^(2)范围内的外来入侵植物进行连续3年的调查,报道了外来入侵植物在城市核心地带的入侵情况。同时对调查区域外来入侵植物的原产地、分布特点、引入途径等进行分析。结果表明:调查范围内共记录到入侵植物42种,分属17科35属。其中,菊科种类最多,有11属14种,占所有外来入侵植物的33.33%。引入途径分析表明:29种植物属于有意引入,占外来入侵物种的69.05%,12种植物属于无意引入,占外来入侵物种的28.57%,1种植物引入途径不详,占外来入侵物种的2.38%。

Based on the continuous 3-year survey of alien invasive plants in Bainiao Park and its surrounding area of 0.483 km^(2) in Shenyang,Liaoning Province,the invasion situation of alien invasive plants in the urban core area was reported in detail.At the same time,we analyzed the place of origin,distribution characteristics,and introduction routes of alien invasive plants in the survey area.As the results showed,a total of 42 species of invasive plants were recorded within the survey area,belonging to 17 families and 35 genera.Among them,Asteraceae had the most species,with 11 genera and 14 species,accounting for 33.33% of all alien invasive plants.The introduction pathway analysis showed that 29 plants were intentionally introduced,accounting for 69.05% of the alien invasive species,12 plants were unintentionally introduced,accounting for 28.57% of the alien invasive species,and one plant was introduced by an unknown route,accounting for 2.38% of the alien invasive species.
