侵蚀率 meaning in Chinese

erosion index
erosion rate
erosion ratio

Surface erosion along the road is about twice as high as the maximum rates reported from the most degraded lands in southeast asia
沿着公路的表面侵蚀率是已报道的东南亚地区退化最为严重的土地最大侵蚀率的两倍。
The results indicated that the ree tracer technology has high precision to quantify the spatial - temporal process of soil erosion ; in earlier rainfall course , the development degree of sheet and nil erosion was general equation ; otherwise in the following course , the rill erosion was dominant in the total erosion , its average erosion acceleration and the average erosion rate was 15 and 9 times of sheet erosion , respectively ; in the end of experiment , the rill erosion took up 90 % of total erosion amount ; the section of slope bottom occupying about 1 / 3 slope area was active erosion segment in this experiment
结果表明： ree示踪技术对定量研究土壤侵蚀具有较高的精度；降雨前期，片蚀与细沟侵蚀发育程度基本相当；后期细沟侵蚀占据坡面侵蚀的主导地位，其侵蚀平均加速度和平均侵蚀率分别是片蚀的15倍、 9倍；试验结束，细沟侵蚀占据坡面总侵蚀的90 % ；本试验条件下，坡面下1 / 3区域为侵蚀活跃带。
