针对以往对土壤风蚀与土地开垦的关系缺乏定量研究，本文以野外实地采集的风沙土样为实验材料，对土地开垦过程中影响风蚀的两个主要因素──地表破坏与植被破坏分别进行风洞实验，结果表明，土壤风蚀率随地表破坏率的增大呈二次幂函数增加；随植被盖度的减少呈指数增加。综合地表破坏及植被盖度对土壤风蚀的影响，最后得出，土壤风蚀率随土地开垦率的增大呈指数增加。在此基础上提出了风沙土开垦中，有效地防止土壤风蚀需要掌握的临界开垦指数以及风沙土开垦所必备的条件。
Aiming at the lack of quantitative research on the relationship between wind erosion and land reclamation in the past, this paper takes the wind-blown soil samples collected in the field as the experimental material, and conducts the wind tunnel on the two main factors affecting the wind erosion in land reclamation ─ ─ surface damage and vegetation damage Experiments show that the wind erosion rate of soil increases quadratically with the increase of surface damage rate and increases exponentially with the decrease of vegetation coverage. Combining the effects of surface damage and vegetation coverage on soil erosion, the paper concludes that the soil erosion rate increases exponentially with the increase of reclamation rate. On this basis, the critical reclamation index needed to be effectively controlled in the wind-blown soil reclamation and the wind-blown soil reclamation are put forward.
