摘要/Abstract

摘要： 运用土壤有机质含量、水稳性团聚体含量、水稳性团粒平均重量直径、团聚度和分散系数等各项指标,对不同树种组成、不同林龄水土保持林的土壤抗蚀性能进行分析、评价.结果表明,水土保持林对于提高土壤抗蚀性能具有重要作用,这种作用主要针对表层土壤而言;与油松纯林相比,油松阔叶树混交林土壤有机质含量较高,水稳性团聚体含量增加了1.71%～38.53%;且随着林龄的增长,水土保持林土壤抗蚀性能不断增强.

Abstract: Indexes including organic matter content, water stable aggregate content, mean weight diameter of water stable aggregate, aggregate degree and disperse coefficient were selected to evaluate soil anti-erodibility of soil and water conservation forests component of different tree species at different ages. The results showed that soil and water conservation forest played an important role in improving soil anti-erodibility, especially to the topsoil. Compared with that of Chinese pine pure forests, Chinese pine broadleaved mixed forests had higher soil organic matter content, and water stable aggregate content increased by 1.71%～38.53%, and soil anti-erodibility was also increased with increasing stand age.
