| 摘 要： | 通过人工雨滴击溅实验,分析了水层厚度、雨滴动能等在相互作用条件下对土壤侵蚀的影响。结果表明,水层厚度越深雨滴动能消耗于水层波动的能量就越多,从而用于击溅土壤的能量就越少;单雨滴溅蚀量随雨滴动能的增大而逐渐增加,动能越大,溅蚀量增加的趋势越明显;水层厚度和雨滴动能一定时,溅蚀量随着距离分布递减。

| Abstract: | In this paper,the effect of thickness of water layer and raindrop energy on the amount of splash erosion was studied.Results showed that the deeper layer of water is,the more rain kinetic energy consumed in fluctuation of water layer is,the less energy used for splashing the soil is;the amount of single raindrop increases with the increasing of the single raindrop kinetic energy;the more kinetic energy is,the more obviously increase of the amount of raindrop is;when the thickness of water layer and the rain... |
