摘要
对曲周试验区 2 8个土壤剖面的研究表明 :大多数土壤冲积层理较明显 ,发育程度低 ,粉砂含量高 ,盐化现象普遍 ,人类活动迹象清晰可见 ,长期灌溉导致明显淋淀粘化层出现。按《中国土壤系统分类 (修订方案 )》,该区土壤分别属于人为土、淋溶土和雏形土 3个土纲中的相应亚纲、土类及亚类 ;按《中国土壤分类系统(普查 )》,分别属于潮土和盐土 2个土类中的相应亚类。比较了 6个土壤代表剖面在
Twenty eight soil pedons in Quzhou experimental region were studied. The results showed that most of soils in this region have little evidence of the development of pedogenic horizons, higher silt content, popular Salic evidence and clearly Argic horizon. According to Chinese Soil Taxonomy (Revised proposal), the soils in the region were classified as Anthrosols, Luvisols and Cambisols respectively.
