摘要
通过大面积实地踏察,对毛里湖湿地外来植物的种类、分布、来源、生活型、入侵生境、引入途径以及危害程度进行了统计分析。研究表明:该湿地公园有外来入侵植物29种,隶属于15科23属;外来入侵动物5种,其中水生无脊椎动物2种,两栖爬行类1种,哺乳类2种。研究还指出毛里湖湿地外来物种入侵的主要途径为国外或外地品种引入管理不当、人类经贸旅游交流或生产活动传播。最后,针对外来物种所处入侵阶段及危害程度提出了不同的防控建议。
The sort,distribution,origin,life type,invasive habitat,introduction pathway and harmful degree of invasive species were statistically investigated and analyzed through a large-scale field survey in the Maoli Lake wetland.The results show that in the wetland park,there are 29 species of invasive alien plants belonging to 15 families and 23 genera,and 5 species of invasive alien animals,including 2 species of aquatic invertebrates,1 species of amphibian and 2 species of mammals.It points out the invasion of alien species mainly arises from the improper management of foreign or ecdemic species introduced,and humans'economic,trade,tourism,exchange and production activities.Finally,it gives control suggestions according to different invasive stages and harmful degrees of alien species.
