Examples
- The analysis on the mechanism of anti - wind erosion of soil crust
土壤风蚀与植被防护研究 - Bare soil is protected from the impact of rainfall which can cause surface soil crusting , compaction , and erosion
塑料薄膜覆盖使裸土免受降雨引起的表土结壳、压实和侵蚀。 - With continuing of rainfall , the influence of soil - aggregated degree was very great . seventhly , mutual effect between soil crust and raindrop splash was studied , the result showed that splash erosion rate was greatly increased , once soil surface crust was formed
七、表土结皮形成对土壤溅蚀的影响：随着表土结皮的逐渐形成，土壤抗侵蚀能力增强，土壤溅蚀速率急剧减小。 - Soil crust , a common phenomenon for many soils worldwide , plays an important role in water and soil losses . soil seals and crusts can significantly reduce soil infiltration rate and subsequently lower the utilization of water resources , increase runoff , and induce heavier soil erosion
造成水土流失一个极其重要的原因是降雨引起的土壤表面结皮，降低了土壤的入渗性能，增加丁土壤表面的径流，加大了土壤侵蚀。 - Secondly , essential law of soil crust formation was obtained : when coarse sand exceeded 50 % , soil crust dominated by depositional crust would be formed . when soil clay exceeded 30 % and soil aggregated degree was less than 140 % , soil surface tended to form soil crust dominated by structural crust
四、土壤聚合剂聚丙烯酰胺( pam )对控制表土结皮形成的效果： pam能控制表土结皮形成的主要原因是， pam能改善土壤的结构状况，显著提高土壤团聚体的稳定性，从而有效的抑制了表土结皮的形成。
