Leaf area index (LAI) is an important parameter
to identify the water balance in forested watershed as a
biological factor influencing directly on the evapotranspiration
in the forest area. The purpose of this study was to
estimate the LAI in a small forested watershed in summer
and winter by applying the Terra/Advanced Spaceborne
Thermal Emission and Reflection Radiometer (ASTER)
data to the LAI estimation method. In this study, the estimation
was based on the absorption and scattering processes
of the solar radiation in the vegetation canopy and
the spectral reflectance characteristics of soil vegetation.
First, we estimated LAI based on Price’s model by application
of ASTER data on the forested watershed located in
the Tenzan Mountains of Saga, Japan. To validate the
results of LAI estimation, secondly, we compared them to
the measured LAI obtained by a plant canopy analyzer
(LAI-2000) on the observation area inside the target region.
This study showed that the LAI estimation method was a
feasible and accurate method as indicated by the high
relationship (r = 0.97) between LAI derived from ASTER
data and LAI measured by LAI-2000. This paper is the first
report on LAI estimation using Terra/ASTER data based
on Price’s model and field investigation. This LAI estimation
method is a reliable and applicable method.
