这分析在无教养的土地上响应土壤侵蚀在土壤在变化 210Pbex 库存学习变化。一个模型被创造在侵蚀用集体平衡的原则在无教养的土地上评估的土壤适合 210Pbex 库存的反应到变化。由处于在无教养的土地的土壤的土壤侵蚀率的变化的数字模拟,我们证明:(1 ) 长被认为决定 210Pbex 的最好的方法的过去的使用在过去的 100 ~ 200 年铺平不是科学地精确的;(2 ) 当在侵蚀在无教养的土地评估的土壤的变化被考虑以后,时间的功能根据索引法律变化,模型在 210Pbex 库存显示出那个变化;并且(3 ) 时间在 210Pbex 库存为变化需要到达一不变被变化在无教养的土地的土壤处于松驰的土壤侵蚀和质量和深度的率影响。这研究的结果能指导努力测量土壤侵蚀率。
This analysis studies changes in the variation ^210Pbex inventory in soil in response to soil erosion on uncultivated land. A model was created to fit the response of ^210Pbex inventory to variations in soil erosion rates on uncultivated land using the principle of mass balance. By numerical simulation of the variation in the soil erosion rate in soil of uncultivated land, we prove: (1) past use of what has long been considered the best method of determining ^210Pbex levels over the past 100 to 200 years is not scientifically accurate; (2) the model shows that variation in ^210Pbex inventory as a function of time varies according to the index law after vari- ation of soil erosion rates in uncultivated land is considered; and (3) the time needed for the variation in ^210Pbex inventory to reach a steady-state is affected by changes in the rate of soil erosion and the quality and depth of relaxation in soil of uncultivated land. The results of this research can guide efforts to measure soil erosion rates.
