摘要:
初步建立了一个不同竞争力外来种入侵的动力模型,并模拟了外来种的竞争力对入侵的影响,以及不同竞争力外来种入侵对栖息地毁坏的响应过程.研究结果表明:(1)外来种入侵首先威胁的是与其竞争力相邻的弱本地种;(2)在外来种成功入侵之后,将导致比其弱的本地种从强到弱依次灭绝;(3)不同竞争力的外来种入侵对栖息地毁坏的响应是随其竞争等级的奇偶性而发生分异,栖息地毁坏对外来种入侵的影响受外来种竞争力和栖息地毁坏程度共同影响.
Abstract:
Invasive alien species are increasingly being recognized as important drivers of ecological change. We have advanced a dynamical model of exotic invasion based on competition and dispersal trade on. The effects of the competition and dispersal abilities on invasion,and the responses of exotic invasion to habitat destruction have been simulated in this paper. The results show that: ( 1) The introductions of alien species will threaten the species with similar competition first,and then the poorer competitors. ( 2) The order of extinction induced by invasive species will rank from the best to the poorest. ( 3) The responses to habitat destruction will vary according to the odd-ranked and even-ranked species.
