摘要：以天津大黄堡省级自然保护区为研究对象，通过样线法对外来入侵植物进行调查，分析和研究保护区外来入侵植物的种类组成、生活型、原产地、区系、入侵途径等。结果表明，保护区内外来入侵植物共27种，隶属于13科21属，其中以苋科的种类最多，有6种;入侵植物以草本植物为主，占入侵植物总种数的
%;入侵植物主要来自美洲，%;入侵途径多样，以有意引入和无意传播途径为主。

Alien invasive plants coming from America account for 70% of the total number of invasive plants invasive plants were most likely introduced both intentionally and unintentionally.
