土壤抗冲性wash durability of soil土壤抵抗风、雨、径流等机械破坏和推移的能力。土壤抗冲性与土壤的膨胀系数、土壤中的根量和土壤硬度的关系密切，膨胀系数愈大，土壤在水中的崩解愈快，其抗冲性则愈弱。同时抗冲性随土壤中根量和土壤硬度的减小而减弱。土壤利用情况不同，抗冲性也有显著差别，其中以林地最强，草地次之,农地最弱。
随着坡度的增加，土壤抗冲性逐渐降低。
Along with slope increase, the soil impact resilience reduces gradually.
不同植被下的土壤抗冲性表现为从林地到荒草地逐渐降低，其中阔叶林地最强；
Under the different vegetation's soil impact resilience performance for reduces gradually from the forest land to the wild grassy slope, the broad-leaf forest land is highest;
除楠竹林外，各林分林地土壤抗冲系数大于农地(1.2 ~ 1.9倍)。林地土壤抗冲性的强弱是其相关因子综合作用的结果。
Except bamboo forest soil, other forest soil anti-scour coefficients are more than one of arable land (be 1.2 ~ 1.9 times), the anti-scour capacity is the result of mutual function of related factors.
