| 摘 要： | 河南省境内的黄土由粉细沙粒、粉粒、黏粒组成 ,其中粉粒含量大于 6 0 % ,黏粒含量一般在 17 3%～ 32 .6 %。黄土的岩土工程性质决定了其侵蚀的强弱 ,研究表明新黄土侵蚀最为严重 ,老黄土次之 ,古黄土较弱。介绍了不同时代、不同地貌区黄土的侵蚀特性 ,提出了相应的土壤侵蚀防治建议

| Abstract: | The loess in Henan Province is composed of fine silt, silt and clay particles, among which, the content of silt particles is greater than 60% and clay particles usually is between 17.3%～32.6%. The rock soil property of the loess has decided the degrees of strong or weak of erosion. It is shown by the study that the new loess erosion is the most severe, the old loess comes second and palaeo-loess is lighter. The paper introduces the characteristics of soil erosion in different times and in different landform regions. It has put forward relevant suggestions on soil erosion prevention and control. |
