摘要:
研究选取内蒙古东部的两种土壤，经过后期的培育使土壤中的CaCO3含量分别达到0%，2%，5%，8%，10%，通过风洞试验分析了CaCO3含量与起动风速、风蚀速率之间的关系。结果表明：（1）随着CaCO3含量的增加，土壤的起动风速呈现先增加后减小的趋势，当土壤中的CaCO3含量约为5%时，起动风速达到最大；（2）不论土壤中CaCO3含量如何变化，风蚀速率都随着风速的增大而增大，但不同风速下，当CaCO3含量约为5%时，风蚀强度最小，风蚀强度随风速的变化趋势较平缓；（3）风蚀速率与CaCO3含量的关系符合二次函数。当碳酸钙含量约为5%时，风蚀速率较小，但由于土壤性质的差异，两种土壤累积风蚀强度不同；（4）将土壤中的CaCO3含量控制在5%左右，风速降低到10 m/s以下时，对防治草原地区土壤风蚀有显著的效果。
Abstract:
Two types of soils from eastern Inner Mongolia, China, were selected as the research samples. Following soil cultivation, the CaCO3 contents in the soils reached 0%, 2%, 5%, 8%, and 12%, respectively. The relationship of CaCO3 contents with threshold wind velocity and wind erosion rates was analyzed through wind tunnel experiment and the following conclusions were obtained:(1) As CaCO3 content increased, the threshold wind velocity for soils first increased and then decreased. The threshold wind velocity was highest when the CaCO3 content was approximately 5%. (2) Regardless of the CaCO3 contents in the soils, the wind erosion rate increased along with wind velocity. However, under different wind velocities, when the CaCO3 content was approximately 5%, the wind erosion intensity was lowest. The wind erosion intensity showed a smooth variation trend in response to the variations in wind velocity. (3) The relationship between wind erosion rate and CaCO3 content could be described by a quadratic function. When the CaCO3 content was approximately 5%, the wind erosion rate was relatively small. However, owing to differences in soil properties, the two types of soils exhibited different cumulative wind erosion intensities. (4) Wind erosion of the soils could be remarkably reduced by maintaining the soil CaCO3 content of around 5% and reducing the wind velocity to less than 10 m/s.
