Dynamics of spectral brightness of the species/age structure for groups of forest types on Landsat satellite images

摘要

The articles presents the results from studying the dependence upon the spectral characteristics of a Landsat 5/TM multispectral high-resolution space image and the species/age structure of forest ecosystems. The parameters that affect the variability of the spectral brightness of forest ecosystems on space images are described for green-moss (hilocominosa), various-grass (larioherbosa), large-grass (magnoherbosa) and sphagnous (sphagnosa) groups of forest types in the Angara taiga region of Eastern Siberia. The trends of dynamics of spectral brightness are revealed for the groups of forest types, depending on the age and share of coniferous species in the structure of forest stands based on the ecological and dynamic analysis of forests, which grow in identical vegetation conditions.
