查询词典 erosion

It was found that, for the control treatment the average runoff depth was 3.72mm per 10mm, the water loss index was 37.2%, the average soil erosion was 43.6 kg*hm-2*10mm-1, and the soil erosion modulus was 7.42 t*km-2*a-1, which are all high in the 4 treatments. For the other three treatments, the surface runoff and the average soil erosion amount were 2.20%-67.08%and 43.81%-90.83%lower than those of the control, respectively. The most effective pattern for soil conservation was the artificial forest with underbrush treatment, and the best water conservation pattern was the treatment of planting tea bush on contour terrace.
