薇甘菊入侵扩散机制研究进展与改进思考

Considerations on Some Issues in Research of the Invasion Mechanisms of an Exotic Weed, Mikania micrantha

摘要:

从薇甘菊(Mikania micrantha H. B. K.)的入侵分布、入侵能力以及群落可侵入性等方面对其入侵机制研究进展进行了分析和总结。以往的研究工作没有重视对薇甘菊入侵过程的整体性研究、对入侵扩散影响因素分析、空间尺度约束影响分析，以及分析方法和技术手段的缺陷。因此，未来应重点开展薇甘菊入侵扩散过程重建及潜在危害区域预测、景观结构对薇甘菊入侵危害的影响等研究，并完善薇甘菊入侵扩散的动态监测网络及风险评估体系。

Abstract:

The research progresses in the invasion mechanisms of Mikania micrantha H. B. K. were summarized, including its distribution and damage, the invasiveness of this weed and the invasibility of native community. It was not pay attention to some areas in previous studies, such as the integrated research of its invasion process, analysis of influencing factors of the invasive spread, the effects of spatial scales, and the defects of analytical methods and technical means. Therefore, in the future, it should focus on the reconstruction of the invasion process and prediction of the potential regional spread, the influence of landscape structure in the invasion, as well as the improvement of the monitoring network and risk assessment system.
