线截抽样调查在热带次生林恢复经营中的应用

The application of line intersect sampling investigation on tropical secondary forest management

整合了线截抽样理论及在热带地区国家森林调查和培育中的经验,并将其应用于热带次生林植被恢复研究的前期调查中。结果显示,这种方法能够解决热带植被类型多样性和分布不均匀带来的调查困难,能够实现林分信息的快速获取,更重要的是能快速了解研究区目标树种的生长和分布状况,为次生林的恢复性经营提供直观参考。

In this study, the method called “line intersect sampling” was introduced to get the stand information in tropic area The results showed that this method can solve the problem of the survey caused by the vegetation diversity and uneven distribution, which was helpful for getting the stand information quickly. What is more, it can let forest managers know the growth and distribution of target trees quickly and provide reasonable insight into secondary forest recovery.
