Changes in traditional plant resources utilization under economic development and globalization

为了弄清热带地区受到经济快速增长和全球化威胁的植物资源的传统利用方式，研究几种植物资源的生境和遗传多样性的最新变化，本研究历时4年。在东南亚大陆的目标地区进行的调查显示，在迁移的耕作地区，休耕林的生态系统正在迅速变化，而在家庭花园中，尽管物种多样性普遍保持不变，但当地关于植物资源利用的知识正在丧失。东南亚大陆地区对野生芒果的利用总体上呈现出多样性，但也存在较大的区域差异。

In order to clarify traditional use of plant resources, which is threatened by rapid economic growth and globalization in the tropics, and study recent changes of habitats and genetic diversity of several plant resources, present research had been carried out for 4 years. The survey in the target areas in Mainland Southeast Asia revealed that in shifting cultivation areas ecosystems of fallow forests were changing rapidly and that in homegardens local knowledge on utilization of plant resources was being lost irrespective of the fact that species diversities are generally maintained. Diversified utilization of wild mango was observed in whole area of mainland Southeast Asia, but there were also large regional differences.
