Abstract :
Spectral mixture analysis method was selected for mapping forest canopy closure in different periods and analyzing the dynamic changes of forest canopy closure with Landsat TM data and field sample data. And sunlit canopy, shaded canopy, sunlit background and shaded background are selected as the four components. In order to conduct the research, Anshan city is selected as the study area. We derive the forest canopy closure of Anshan city in 1990, 2000, 2006, then analysis the dynamic changes of Anshan forest canopy closure during these periods. The result shows that Anshan forest canopy closure shows a downward trend from 1995 to 2000, and shows an upward trend from 2000 to 2006.
