When the coverage ratio of floodplain area reaches to 30%, the wind erosion can be controlled within the range of light erosion.
河滩土植被覆盖率达到30%时即可将风蚀控制在轻微侵蚀范围内。
2
The principle and characteristics of the nuclides ratio technology are introduced , using several nuclides compoundly to distinguish soil erosion processes and to estimate soil erosion rate ;
阐述了核素比率应用的原理、特点及其能更为敏感地反映土壤侵蚀速率和过程等优点；
3
It measures wind erosion under the conditions of different wind speed of floodplain area with different vegetation coverage ratio of the Yongding River by using mobile filed wind channel equipment.
