以川北地震灾区不同植被恢复模式（慈竹林、茶树林、喜树林、柳杉林和农耕地）为对象，研究土壤抗蚀性，并探讨土壤有机质与抗蚀性指标之间的关系。结果表明：植被恢复后水稳性团聚体平均重量直径、结构性颗粒指数、团聚状况和团聚度增加，土壤结构体破坏率、不稳定团粒指数、分散率、侵蚀系数和受蚀性指数降低；不同植被恢复模式土壤抗蚀性综合主成分值呈现出慈竹林〉茶树林〉喜树林〉柳杉林〉农耕地的规律；土壤有机质与绝大多数土壤抗蚀性指标呈显著相关。说明土壤有机质能较好地表征土壤抗蚀性，慈竹林对于提高研究区土壤抗蚀性具有重要的作用和意义。

Soil anti-erodibility and its relationship with soil organic matter （SOM） were studied under the different vegetation patterns, including Neosinocalamus affinis （ NAP）, Camellia sinensis （ CSP）, Camptotheca acuminate （CAP） and Cryptomeriafortune （CFP） plantations,and farmland （CK） in the seismic disastrous area of Northern Sichuan province. The results indicated that the mean weight diameter of water stable aggregates, structural grain index, aggregation status and degree of aggregation increased, while the percent of construction destructive, instable aggregate index, dispersion rate, erosion coefficient and eroded index decreased after vegetation restoration. The principal component values of soil anti-erodibility of 5 different vegetation patterns followed the order： NAP 〉 CSP 〉 CAP 〉 CFP 〉 CK. Soil organic matter was significantly correlated with most of soil anti-erodibility indexes. This indicated that SOM could be used to evaluate soil anti-erodibility and NAP was important to enhancing the soil anti-erodibility in the study area.
