ChineseJournal of Ecology,2002, 21(5):30 ~ 39. long with more and more serious reductions of forest areas and biodiversity in tropical and subtropical forests, especially with the spring up ofmolecular ecologyand the advance ofthis tool used in tropical and subtropical plant populations,there2 search of genetic structure and genetic diversity in the forests has been focused on in modern ecological topics. Molecular markers are of the utmost importance and efficiency to revealing the ecologically essential aspects, genetic structure, popula2 tion genetic differentiation in processing communities, coevolution, speciation and the ecological efficiency of transgenic plants. Strengthening molecular marker utility in forest ecology is necessary and widely perspective on forest management and biodiversity conservation, whatever for the theory or applilation of ecology. Key words:tropical rain forests, subtropical forests, biodiversity,molecular ecology, molecular markers. :热带雨林, 亚热带森林,生物多样性, 分子生态学, 分子标记物 :Q948. 1 : :1000- 4890(2002)05- 0030- 10 [14] [10] 当前, 植物学家会有更多的方法和手段来从事 体的地理分布的问题 , 其结果更为准确 。例 植物学的研究, 如分子生物学方法、遗传学的方法、 如,在植物地理系统学的研究中,没有化石资料就难 植物生理学的方法、分类学方法等。其中分子生物 以判断一个物种是冰期残遗种还是冰期过后的迁移
