| Summary: | 碩士 === 國立中興大學 === 土壤學系 === 86 === Estiamting the evapotranspiration and plants' transpiration
on terrestrialsurface are very important basic researches
because the researches could be beneficial to understand the
energy flow of terrestrial surface and the plants'water
consumption and yield. Scientists still have not set up a cheap
and effective method to monitor the evapotranspiration and
plants' transpiration in field and developed a generally
analytical or experimental solution that could be fitted in all
conditions. Feddes et al. developed a model called SWATR by
using Penman equation had ever been calibrated and validated in
Denmark and Australia. That was a great approach to estimate the
potential evapotranspiration and plants' transpiration on big
territories. How suitable SWATR on Taiwan was still hidden on
heaven. So the missions of this researchwas to seek Taiwan's
potential evapotranspiration and plants' transpiration and test
its reliability. We discovered that the output values of SWATR
model were very exact. The mutiple regression showed that SWATR
model could be transformed into regressive model without losing
its effect if it applied in a small area that had the
characteristics that were the plants' factors and soil factors
were constant and the vibrations of the meterological factors
were small.
