在军事训练区演习时 ,作战车辆会破坏植被、改变地表、破坏土壤团聚体、压实土壤并形成车辙。土壤压实后往往会增加地表径流量和径流存滞时间 ,车辙则传输地表水流。与坡面径流相比 ,车辙传输的水流具有更高的速度和更强的紊动性 ,沿坡面能分散和搬运更多的泥沙从而导致车辙内 During exercises in military training zones, combat vehicles destroy vegetation, change the surface, destroy soil aggregates, compact soil and form ruts. Soil compaction tends to increase surface runoff and runoff retention time, while rutting transports surface water. Compared with runoff, rutting flows have higher velocities and stronger turbulence, and more sediment can be dispersed and carried along the slope resulting in rutting
