为推广应用中国土壤系统分类 ,本文对自然地理野外实习基地—河北省秦皇岛市石门寨区域的土壤进行系统分类研究。结果如下 :土壤诊断层有淡薄表层、水耕表层、雏形层、水耕氧化还原层、粘化层 ,诊断特性有砂质沉积物岩性特征、石质接触面、半干润土壤水分状况、湿润土壤水分状况、人为滞水土壤水分状况、氧化还原特征、冷性土壤温度状况、温性土壤温度状况 ,土壤类型归属为人为土纲、淋溶土纲、雏形土纲和新成土纲。并与原土壤地理发生分类进行参比及总结地理分布规律
In order to popularize the application of soil taxonomy in China, this paper systematically studies the soil classification of the Shimenzhai area in Qinhuangdao City, Hebei Province, as a natural field practice base. The results are as follows: The diagnostic layer of soil has light surface layer, hydroponic surface layer, embryonic layer, hydropodic redox layer and sticky layer. The diagnostic features are the lithological characteristics of sandy sediments, the contact surface of rock, the moisture content of semi- Wet soil moisture status, artificial water retention soil moisture status, redox characteristics, cold soil temperature conditions, warm soil temperature conditions, soil types belong to the human soil class, leaching soil class, rudimentary soil class and new soil group. And with the original classification of soil geography for reference and summary of the geographical distribution
