摘  要：
【目的】探索土壤侵蚀强度与磁化率(MS)之间的关系,为利用磁测法研究紫色土坡面侵蚀提供理论依据。【方法】通过土壤侵蚀序列方法,研究川中丘陵区紫色土在坡面侵蚀过程中基本理化性质与磁化率(MS)的演变特征。【结果】结果表明,随土壤侵蚀强度的增加,坡顶和坡中土壤基本理化性质的演变特征存在差异,坡中土壤要比坡顶土壤复杂。在坡顶以0~20 cm土壤层为主要营养物流失层,在坡中则以0~40 cm为主。不同侵蚀强度土壤与未侵蚀土壤相比较,只有坡顶土壤中有机质(SOM)的含量和坡中土壤全钾(TK)的含量达到显著差异,而土壤中其他的养分含量均未达到显著差异。土壤侵蚀对紫色土SOM、N和P的保存不利。表层土壤的MS随土壤侵蚀强度的增加有所下降,但并没有呈现出固定的模式,在本研究区很难借助MS来反演紫色土的侵蚀过程。【结论】川中丘陵地区土壤侵蚀主要体现在坡中,其次是坡顶,且土壤肥力受到显著影响。因此,应在该地区水土保持与生态修复时因地制宜选择适合的侧重点。

摘  要：
【Objective】 To explore the relationship between soil erosion intensity and MS,provide a theoretical basis for using magnetic method in the study of purple soil erosion.【Method】The evolutional characteristics of basic soil properties and magnetic susceptibility(MS)during the purple soil slope erosion processes in the central Sichuan hilly region were analyzed in this study by sequence method of soil erosion.【Results】Results show that the evolutional characteristics of the basic soil properties have some difference between the top and middle of slope and it appears much complicated in the middle of slope.The soil layers of nutrient loss at the mountaintop were 0~20 cm,and were 0~40 cm at middle of slope.Different degree of soil erosion are compared with no erosion of soil,only the content of soil organic matter(SOM)and total potassium(TK)in the top and have been reached statistically significant differences in top of slope,but the content of other soil nutrient did not reach a significant difference. Soil erosion is a elements of the adverse for the protection of SOM,N and P of on purple soil. With the increasing of soil erosion intensity,the MS of the top soils decreased but there was no fixed pattern and it couldn't be used to retrieve the soil erosion processes in the study region.【Conclusion】The soil erosion from a hilly area in central Sichuan is mainly appeared in middle of slope and the soil fertility was significantly affected. Thus conservation of soil and water and ecological restoration should select suitable emphasis in this area.
