研究表明,黄土高原土壤崩解速率存在明显的地域分异规律,且呈现出自西北向东南次第减慢的趋势。根据主要参数,将研究区内土壤崩解速率划分为极慢、很慢、一般、很快和极快5个区。影响土壤崩解速率的主要因素有:农业耕作、植(生)物生长和土壤成土过程三个方面。还发现,土壤崩解速率与土壤抗冲性之间存在密切的幂函数关系。
The results show that there is a clear regional difference in the rate of soil disintegration in the Loess Plateau, and shows a tendency of slowing down from the northwest to the southeast. According to the main parameters, the rate of soil disintegration in the study area is divided into extremely slow, very slow, normal, fast and extremely fast 5 areas. The main factors affecting the rate of soil disintegration are: agricultural cultivation, growth of plants and animals, and soil formation process. It was also found that there was a close power function relationship between soil disintegration rate and soil impact resistance.
