在泰国,龙脑香科有8个属、65种.属于印度—缅甸、印度—中国和马来西亚三个植物区系成分,其中马来西亚成分占优势。在泰国的干旱落叶龙脑香林中共有5个旱生树种,缠结羯布罗香(Dipterocarpus intricatus)、钝叶羯布罗香(D.obtusifolius)、羯布罗香(D.turbinotus),钝叶娑罗双(Shorea obtusa)和暹罗娑罗双(S.siamensis),它们常混生在一起,有时成为纯林。其他的龙脑香科树种都属于热带常绿雨林和干旱常绿林的成分。分布在石灰岩和其他岩系的有铁坡垒(Hopea ferrea)、灰青皮(Vatica cinerea)、罗氏娑罗双(Shorea roxburghii)、云南娑罗双(S.assamica)和暹罗娑罗双。对泰国龙脑香科的一些树种的更新、生态特性、生长速度和物候学的营林观察作了简要讨论。
In Thailand, there are 8 genera, 65 species belong to the three flora of India - Myanmar, India - China and Malaysia, of which Malaysia ingredients predominance. There are 5 species of xerophthalmus in the dry, deciduous forest in Thailand, Diptocarpus intricatus, D. obtusifolius, D. turbinotus, Shorea obtusa and S. siamensis, often mixed together and sometimes become pure forests. Other Monochamus species belong to the tropical evergreen rain forest and arid evergreen forest composition. Hopea ferrea, Vatica cinerea, Shorea roxburghii, S. assamica and Siam Milo distributed in limestone and other rock series. A brief discussion was provided on the regeneration, ecological characteristics, growth rate, and phenology of some species of Monochamus in Thailand.
