| 中文摘要 | 汶川地震形成了大面积的震裂带，震裂带内水土流失严重。本文重点从土壤结构体分形维数、有机质含量、土壤抗冲性三个方面探讨了北川震裂带柳杉林地土壤结构功能特性，分析了地震裂隙程度对土壤结构体分形维数、有机质含量、土壤抗冲性的影响及其与土壤深度的相关胜。结果表明地震裂隙程度对土壤结构体分形维数影响不显著，而地震3a后强度裂隙样地土壤有机质含量、抗冲性大于中度裂隙或弱度裂隙样地；各样地土壤有机质含量、抗冲性与土壤深度显著负相关，有机质含量与土壤抗冲性存在显著的正相关关系。 |
| 英文摘要 | Chen xiaoyan1,2, Wang daojie1,2, Chen dong1,2,Chen shun1,2,3 (1 Chengdu Institute of Mountain Hazards and Enviroment,CAS,chengdu,610041. 2 key laboratory of Mountain Hazards and Earth surface process ,CAS 3 Graduate University of Chinese academy of sciences, Beijing ,10049) Abstract: A huge area of soil surface rupture zone was produced by WenChuan Earthquake, in which the soil and water loss is very severe. In this paper the soil structure function characteristics was emphasized from soil aggregates fractal dimension, soil organic matter content and soil anti-scouribility, and also studied the effects of rupture level to the soil aggregates dimension, soil organic content, soil anti-scouribility, and its relationship with soil depth. The results suggest that the rupture level has little influence to soil aggregates fractal dimension, and soil organic matter content of severe plot is more over than that of slight rupture plot or moderate plot, and the anti-scouribility of severe plot soil is also stronger than that of slight or moderate plot in the same soil layers after earthquake happened three years later. Soil organic matter content,anti-scouribility demonstrates a negative relationship with soil depth, and soil organic matter content has a positive relationship with soil anti-scouribility. |
