外来入侵植物禾叶慈姑的研究进展

Research Advances of Invasive Alien Plant Sagittaria Graminea

禾叶慈姑(Sagittaria graminea)原产于北美洲,经由澳大利亚传入我国,因其密集的克隆生长,具有强烈的排他性,会改变入侵地的生物多样性。我国对禾叶慈姑的研究主要集中于入侵生态学、水体净化和园林规划三个方面。本文从生物学特征、分布区域概况、入侵机制及利用等方面阐述禾叶慈姑的研究进展,以期为进一步研究禾叶慈姑的入侵机理、防治及利用提供参考。

Sagittaria graminea,originating from North America,was introduced into China through Australia.Because of the dense clone growth it has strong exclusiveness,it will change the composition of biodiversity in the invasive areas,so it is necessary to study the species.The research on Sagittaria graminea in China mainly focuses on three aspects:invasion ecology,water purification and garden planning.Research advances in the biological characteristics,general situation of distribution area,invasion mechanisms and utilization of Sagittaria graminea are reviewed in this paper,and a reference for further research on the invasion mechanism,prevention and application of Sagittaria graminea are provided.
