分子标记技术在入侵生态学研究中的应用

外来入侵物种给农林业生产造成了巨大的经济损失，并威胁生物多样性及人类健康．入侵生态学的研究对于认识外来入侵物种的入侵机制及其可持续控制具有重要意义．分子标记技术为解决入侵生态学研究中的许多基本问题提供了良好的手段．本文综述了该技术在外来入侵物种的鉴定、地理分布、原产地、传播模式、种群遗传变异、杂交及基因渗入等研究中的应用现状，并对其应用前景进行了展望．

Application of molecular marker techniques in invasion ecology

Alien invasive species can cause huge economic loss in agricultural and forestry production, and threaten biodiversity and human health. The research of invasion ecology is of significance in understanding the invasion mechanisms of alien invasive species and in developing corresponding sustainable control methods. Molecular marker is regarded as a useful tool in approaching some essential issues in the research of invasion ecology. In this paper, the applications of molecular marker techniques in the studies of identification, geographic distribution, invasive source, spread pattern, genetic variation, hybridization, and gene introgression of alien invasive species were reviewed, and the application prospects were discussed.
