河口湾地区的生物入侵研究现状

Present Situation of Biological Invasions in the Estuaries

生物入侵对当地生态系统造成了巨大破坏,目前已经成为威胁全球生物多样性和影响生态系统稳定性的最为重要的因素之一。根据国内外生物入侵研究文献,对入侵河口湾地区的主要动植物的种类、特点和危害等进行概述,针对我国研究现状提出应在以下几个方面加强研究:①尽快开展主要河口湾地区的调研工作,确定入侵物种名录;②开展对关键入侵物种的历史和途径、种类及预防、控制方法等方面的研究;③加强有害生物的生物学、生态学、遗传学、毒理学、管理学等研究。

Biological invasion has received considerable attention recently due to their increasing impacts on local ecosystems and is becoming one of the six most serious environmental problems that may influence the future economical and social development. And it has become one of the most important factors that is threatening biodiversity and stability of ecosystems in the world. Presentation was made on species, biological characteristics and damage of invasive plants and animals in the estuaries in the world based on literatures of biological invasion at home and abroad. Propositions were offered such as determination of invasive species name list, history and way of invasions, forecasting and control of invasive lives, as well as researches on biology, ecology, genetic, toxicology and management of invasions in China.
