外来有害植物种群扩散的综合测定方法

在外来有害植物试点调查的基础上,结合外来有害植物的特点,介绍了外来有害植物种群测定的样地选择和设置方法.对外来有害植物入侵生境条件、有性繁殖能力、无性繁殖能力及入侵现状评价、种群扩散测定的内容和计算方法进行了概括.并根据以上资料,计算了外来有害植物综合分析指数,分析外来有害植物入侵现状以及发展趋势,为综合治理外来有害植物提供参考资料.

Integrative Method in Determing Population Diffusion of Exotic Harmful Plants

According to a database of plot sampling on exotic harmful plants combined with the characteristics of exotic harmful plants, we introduced a new method in selecting and setting plots to determine the harmfulness of such plants. The determination content and calculation method of the diffusion ability of exotic harmful plants were determined by parameters of inva- sion environment conditions, the ability for sexual reproduction and asexual reproduction, and invasion status evaluation. We also calculated the invasion integrative analysis index of exotic harmful plants on the basis of the above results, to order to analyze the invasion status and development direction and determine integrative control of exotic harmful plants.
