摘要
在持续１０余年对我国特有珍贵树种长叶榧树的分布区、生长环境、生物学特性调查研究基础上，全面系统地提出了该树种保护措施与开发利用意见。
Habitat fragmentation and population isolation are of increasing concern in the management of wildlife resources. With the information of population genetic heterozygosity, incorporating population demorgraphic data and status of the habitat in which the population lived, we can analyse the genetic effect of demorgraphic stochasity on local populations, the effect of habitat heterogeneity on population genetic structure, and estimate gene flow among geographic populations, the level of population differentiation. It is of great value in the management practice of endangered species, planning for population restoration and designing of nature reserve.
