以春陵江为例,研究其流域主要林分抗损毁能力,综合考虑对春陵江流域主要林分起主要作用的环境因子、干扰因子、结构和功能因子,采用层次分析法筛选出了16个子因子构建评价指标体系,将损毁度值分为轻微损毁、低度损毁、中度损毁、高度损毁和极度损毁5个等级来分析主要林分抗损毁能力。结果表明:春陵江流域主要林分抗损毁能力由强到弱依次为杉木林组、常绿阔叶林、落叶阔叶林组、灌木林组、松木林组、竹林、杨柳林组。流域主要林分抗损毁能力研究对森林生态系统恢复、优化及研究林木抗灾能力都有重要意义。

Taking Chunling River as an example to study the anti-damage capability of the ecosystem in this valley. 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 type...
