| 摘 要： | 生态安全是指自然和半自然生态系统的安全,即生态系统完整性和健康的整体水平反映.20世纪以来,随着国际贸易、旅游的发展和人们交往的增加以及全球环境的变化,生物种类在全球扩散的机会也大大增加,外来种入侵已成为一个全球性的问题.生物入侵一般包括有意引进、无意传入和自然入侵三种途径.它通过改变物种组成,破坏生物多样性;改变种群结构,破坏生态平衡;造成污染生态环境,影响人畜健康,威胁着全球的生态环境和经济发展.

| Abstract: | Ecological security indicates the security of the natural and semi-natural ecosystem that encompass the integrity and health of the ecosystem.Since the 1900's,with the development of international trade and tourism,the increase of communication and the change of global environment,the opportunity of biological species diffusion globally will increases.The invasion of exotic species has become a problem on a global scale.Biological invasion includes intended-unintended introduction and natural invasion.It changes composition of species,damages biodiversity,changes structure of species,damages ecological balance,pollutes ecological environment,effects the healthy of human and livestock,threats global ecological environment and the development of economy. |
