中文摘要对紫色丘陵区土壤侵蚀链不同地形部位的紫色土壤进行了采样和分析。研究发现。紫色丘陵区土壤侵蚀链中土壤性质随地形呈规律性变化特征,与冲刷剥离、搬运扩散及掩埋沉积作用的强度有关。该区坡顶、坡中土壤由于冲刷剥离、搬运扩散作用强烈,加之农耕改造作用,理化性质恶化,因此不适于农用;而坡脚掩埋沉积作用占主导作用,农用后仍可保持良好的土壤性质,适于农业利用。
英文摘要The samples of purple soil came from different landform characteristics of the soil eroive chain in purple hilly region were analysed.
The results showed that the basle soil feature in soil erosive chain varied according to landform characteristics in purple hilly region
and related to the intensity of the washing and denudation,transiting and diffusing and sediment and burying.As the intensive washing
