Conversion of tropical dry forest to rubber plantation is widely observed in Southeast Asia at present. We conducted soil survey in seasonally dry tropical forests and rubber plantations in Cambodia to clarify the temporal changes in stock and physical composition of soil organic carbon during the land use change. The labile carbon pool in forest soil which is composed of fine plant debris rapidly decreased after the clear cutting of forest and planting of rubber trees. On the other hand, the impact of re-planting of old rubber plantations on soil organic carbon pool was small compared to that of the establishment of new rubber plantations.

目前，热带干燥林向橡胶种植园的转变在东南亚地区十分普遍。我们对柬埔寨季节性干旱的热带森林和橡胶园进行了土壤调查，以明确土地利用变化期间土壤有机碳储量和物理组成的时间变化。森林砍伐和种植橡胶树后，由细小植物碎片组成的森林土壤中的不稳定碳库迅速减少。另一方面，与新建橡胶园相比，重新种植老橡胶园对土壤有机碳库的影响较小。
