With a systematic consideration to environmental factors, interference factors, structural and functional factors which play major roles in the forest stand of Chunling river, the damagedegreeisdividedto 5 levels as tinydamage, lowdamage,moderatedamage, fulldamageandseveredamageby choosing 16 indexesrepresenting the characterizationsof weakness to analyze the anti-damage capability of forest ecosystems.The result shows that the anti-damage capability of Chunling River main forest stand types in which Chinese Fir Stands was the strongest and then ever green broadleaved forest, deciduous broadleaved forest, shrubbery, pinewood, Bamboo, willow. Assessing the anti-damage capability of forest ecosystem is of great s
