摘要
欧洲千里光是菊科千里光属植物,在中国为入侵植物。目前我国对欧洲千里光入侵状况研究很少,且不同文献对其分布的描述也不一致。通过收集和分析文献资料、数据库记录,澄清欧洲千里光在中国的分布研究中存在的问题,并通过在湖北、黑龙江、青海等9个省份的野外调查,初步分析了欧洲千里光在中国不同地区的生长状况和入侵现状。结果表明:欧洲千里光在中国新疆、青海、甘肃、陕西、山西、内蒙古、河北、黑龙江、吉林、辽宁、山东、浙江、上海、西藏、四川、重庆、云南、贵州、湖北和台湾20个省份(自治区或直辖市)都有分布;欧洲千里光可能沿着公路进行传播,在农田生境中生长最好;目前欧洲千里光在中国的入侵风险较小,个别地区存在潜在危害;对分布记录较多的中国东北地区、西南地区、西北部分地区,尤其是农田应进行长期监测,一旦发现欧洲千里光扩散,可以采取生物防治和化学防治等多种方法相结合来控制其危害。
Senecio vulgaris L.(Asteraceae)is an invasive alien plant in China.Few studies have been conducted on the invasion status of S.vulgaris in China,and description of distribution of S.vulgaris in different literature is inconsistent.This paper tries to figure out the distribution of S.vulgaris in China by collecting and analyzing distribution records from literature and on-line database,as well as by field investigation on S.vulgaris populations in 9 provinces of China,such as Hubei,Heilongjiang and Qinghai.The results indicate that S.vulgaris distributes in 20 provinces(municipalities,or autonomous regions)in China,including Xinjiang,Qinghai,Gansu,Shaanxi,Shanxi,Inner Mongolia,Hebei,Heilongjiang,Jilin,Liaoning,Shandong,Zhejiang,Shanghai,Tibet,Sichuan,Chongqing,Yunnan,Guizhou,Hubei,and Taiwan.Senecio vulgaris is likely to spread along the roads and grows best in farm fields.The invasion risk of S.vulgaris in China is low,but there are potential hazards in some regions,such as in northeast and southwest China,where the occurrence records are high.These areas should be under long-term monitoring,especially in habitats like farm fields.Combination of biological and chemical methods can be used to control the invasion of S.vulgaris in China.
