外来物种入侵对生物多样性的影响

摘 要:在经济全球化的今天，外来物种入侵已日益成为一个全球性的热点问题。过去的高山险脉、海洋河流和交通不便等阻碍外来物种有意或无意的引入的自然因素在贸易全球化的今天和旅游业飞速发展的条件下已逐渐淡化，外来物种随着人口流动和交通运输已大量的传入。由于自然生态系统的错综多样，人员流动，物品流动太过频繁，所以外来物种的传入不易受到监控，因此生物入侵的危害在全球都已经十分严峻。本文主要在我国以及国外已有的外来入侵物种调查研究的基础上， 分析其主要的入侵途径、经济和自然危害，探讨如何有效防治外来物种入侵的方法，为保护世界生物多样性的安全和减少物种入侵带来的损失献计献策。

comprehensive eva luation and early warning method of the impact of invasive species on biodiversity
Abstract: In the economic globalization today, invasive species has increasingly become a global hot issue. Past alpine insurance veins, rivers and inaccessible marine alien species, such as obstruction, intentionally or unintentionally introduced natural factors have gradually fade under the conditions today, the rapid development of trade and tourism, globalization, migration and alien species with transportation have a lot of incoming. Because of the intricate and diverse natural ecosystems, the movement of persons, goods flow too frequently, so the incoming alien species susceptible to monitoring, therefore harm biological invasions in the world have been very severe. In this paper, the basis of invasive alien species and research abroad has been on the analysis of the main invasion route, economic and natural hazards, explore ways how to effectively control invasive alien species, in order to protect the safety of the world's biodiversity and reduce losses caused by invasive species brainstorming
key words：Invasive alien species; loss; Biodiversity; Control methods.
