Forest fire and vegetation changes in tropical seasonal forests in Thailand.

利用森林火灾产生的木炭和蛋白石植硅体研究了泰国热带季节森林的植被变化。至少10000年前，泰国发生了森林大火。火烧频度对森林植被的影响表现为：频繁火烧引起的落叶双翅果林被混交落叶落叶阔叶林取代，然后是森林火灾减少的常绿林。与目前的分布相比，热带季节森林被认为是分布在较低纬度地区。本研究中使用的蛋白石植硅体分析对研究过去植被的变化是有用的。

Vegetation changes of tropical seasonal forests in Thailand was investigated using wood charcoal produced by forest fire and opal phytoliths. Forest fire occurred in Thailand at least 10000 years ago. The frequency of fire seemed to affect the forest vegetation: frequent fire induced deciduous dipterocarp forests, which were replaced with mixed deciduous forests, and then with evergreen forests with decreasing forest fire. Tropical seasonal forests were considered to be distributed to lower latitude area compared to the present distribution. Opal phytolith analysis used in this study was useful in studying past vegetation changes.
