Abstract
The evapotranspiration is related with water and energy circulation, climate change, ecosystem productivity and also it is important process in water and nutrition of ecosystem. The evapotranspiration is closely related with ecosystem services that is defined all kind of benefits from ecosystem, however many studies focused on estimation of evapotranspiration in Korea. In this study, estimates the evapotranspiration using precipitation, plant available water index, potential evapotranspiration. In processing for plant available water index, used ecological map, MODIS (MODerate-resolution Imaging Spectroradiometer) NDVI(Normalized Difference Vegetation Indec) & EVI(Enhanced Vegetation Index) and computed 4 different methods and then conducted accuracy assessment using RMSE(Root Mean Square Error) from comparing with Penman-Monteith Equation. Result of RMSE range of daily evapotranspiration are from 1.3mm to 1.54mm and final result represented Green Water Flux for connecting the ecosystem services. Finally land cover classification using ecological map is the most accurate method for estimation of evapotranspiration.
