loss by erosion meaning in English

层序的侵蚀的间断

The question that soil erosion causes loss of soil nutrient and leads to degradation of land productivity has received many attentions . but the research on soil potassium loss by erosion is under study
土壤侵蚀引起土壤养分径流流失，导致土壤生产力降低这一问题已引起人们普遍关注，但有关土壤钾素径流流失研究方面的报道不多。
In this thesis , with eight events of artificial water - washing test on five different slope gradients , factors affecting soil potassium loss by erosion , such as slope gradient , rain intensity , vegetation coverage , and amount of rainfall are discussed
本文通过在5个不同坡度径流小区进行的8次人工模拟冲刷试验，探讨了坡度、放水冲刷强度、植被和降雨量等因素对土壤钾素径流流失的影响。
The results can be used to understand dynamics of soil nutrient transfer in slope land , provide essential for establishing model of soil potassium loss by erosion , recommend rational fertilization application , and increase land productivity
研究成果对深化坡面土壤养分迁移动力学研究有一定的理论意义，可为建立土壤坡面钾素径流流失模型提供基础资料，并对坡地合理施肥、提高土地生产力有一定的指导作用。
