加拿大一枝黄花Solidago canadensis是原产于北美的菊科Asteraceae多年生草本植物, 上世纪30年代引入我国, 现广泛分布于我国东部地区的部分省市, 并已成为该区域的农业和环境杂草。为了预测加拿大一枝黄花在我国的潜在分布区, 本研究采用相同气候方法对其进行了估测。我们用加拿大一枝黄花的原产地——美国的气候参数作为参照, 将其与我国各地气象站的气候数据进行匹配。结果表明, 加拿大一枝黄花在我国的潜在分布区的纬度跨度为25°–50°, 所以其潜在的入侵区将远大于目前的实际分布区, 甚至东北的部分地区也将适宜于该物种的生长。据此, 我们建议相关管理部门应加强该物种的监测工作, 以防其进一步向目前入侵区以外的周边地区蔓延。
Solidago canadensis is a perennial herbaceous Asteraceae native to North America. It was introduced to our country in the 1930s and is now widely distributed in some provinces and cities in the eastern part of China. It has become an agricultural and environmental weed in the region. In order to predict the potential distribution of Solidago canadensis in our country, this study estimated the same climate method. We use the Canadian origin of Solidago, the climate parameter of the United States as a reference, and match it with the climatic data of weather stations across China. The results show that the potential range of Solidago canadensis in China is between 25 ° -50 ° latitude, so the potential invasion area will be much larger than the current actual distribution area, and even some parts of the Northeast will be suitable for the growth of this species . Accordingly, we suggest that relevant authorities should strengthen the monitoring of the species to prevent further spread to the surrounding areas beyond the current invasion area.
