3.3 Relationship between LST and vegetation fraction
Previous studies of relationship between vegetation and
temperature[16~18] have proposed a new method ‘ triangle
method’, by which the relationships of three parameters, (i.e.,
vegetation, surface moisture availability and temperature) were
discussed. In this study, scatter plots were used to study the
relationships between brightness temperature and vegetation
fraction. The results are presented in Fig 4, and
the character of the space is nearly triangle. Because when
NDVI reached 0.6 or more, where 100 percent vegetation
fraction was identified, spatial characteristics of the show were
not entirely a triangle
