    摘要:

    [目的] 刺萼龙葵是20世纪80年代入侵我国的检疫性外来植物,目前已在东北和西北地区广泛分布并对农牧业生产造成极大危害,急需明确其时空分布格局和潜在扩散动态,为其早期监测预警提供依据。[方法] 首先,利用实地调查、标本和文献查询途径获得的地理分布信息重建刺萼龙葵在我国的扩散历史和分布格局;其次,通过物种分布模型预测其潜在的分布区;最后,融合时空动态和潜在的扩张趋势,利用空间分析模型划定早期监测预警的区域。[结果] 刺萼龙葵最早于1980年在辽宁省朝阳市被发现,其后不断沿河流和公路等扩散蔓延。2000年以后相继在内蒙古、北京、河北、吉林以及新疆等省区发现其入侵种群。截至目前,已扩散到了7个省的54个县区。适生区预测结果表明,其在我国存在广阔的潜在分布区,目前还处在快速扩散阶段,没有达到饱和阶段。[结论] 刺萼龙葵在我国还处在快速扩散阶段,远没有达到饱和,华北平原是其潜在扩散的高风险区,建议加强对其扩散前沿带包头、张家口、北京、秦皇岛一线的监测力度,以抑制其进一步扩散蔓延。

    Abstract:

    [Aim] Solanum rostratum Dunal, a quarantine weed, invaded China in 1980s. S. rostratum has become widely distributed in northeast and northwest of China and is causing huge damage to the local agricultural production. It is imperative to identify its geographic distribution pattern and dispersal potential to establish effective management measures and prevent further invasion.[Method] Here, we first reconstructed the historical invasion process of S. rostratum in China based on field investigations, herbarium records, and published literature. Secondly, Maxent ecological niche modeling was applied to predict the potential distribution of S. rostratum in China. Finally, the high risk areas for potential invasion were identified.[Result] S. rostratum first invaded Chaoyang County, Liaoning Province, northeast China in 1980. It then spread along the road and rivers to the neighboring regions. After 2000, it was found in the Jilin, Neimenggu, Xinjiang, Hebei provinces. Until now, it invaded 54 counties in 7 provinces. Maxent modeling prediction showed that there is a large area suitable for survival of S. rostratum in China.[Conclusion] Its invasion process showed that it is still in the expansion phase and has not yet occupied all climatic suitability areas in China. North China plain were identified as high risk for potential expansion. Monitoring should be enforced where current invasion front and high risk areas are found, such as in the regions along the Baotou, Zhangjiakou, Beijing and Qinhuangdao, to find the invaded populations as early as possible and prevent or mitigate its expansion toward neighboring areas.
