| Research Abstract |
We partitioned transpiration from overstory trees and understory vegetation in a Cambodian lowland deciduous forest. The contribution of overstory trees to evapotranspiration from the whole ecosystem was 50-60%, while that of understory vegetation was 40-50%. We predicted 3℃-increase in mean surface temperature based on the surface-conductance models of overstory and understory, if overstory trees were clearly cut. Remarkable changes in environment will be caused by decreases in overstory trees due to the rapid economic growth in Cambodia.
