摘要
依据《中国土壤系统分类 (修订方案 )》和《中国土壤系统分类———理论·方法·实践》的原则与方法 ,选择江宁县淳化镇的低丘岗地和冲地农田 (70 0hm2 )作为典型区段。按照景观、地貌与母质类型 ,设置了 5 1个土壤观察剖面 ,并采集土壤剖面各层段土样进行理化分析。最后拟定出 11个特征土层 ,划分出 6个土系。
According to the principles and methodology of Chinese Soil Taxonomy(revised proposal),the low hilly land and farmfields(700 hm 2)in Chunhua Town of Jiangning County,Jiangsu Province were selected as a typical area for soil taxonomy at lower category.Fifty one soil profiles varying in natural landscape,landforms and parent materials were observed and some soil chemical and physical properties were analyzed.Eleven soil characteristic horizons and six soil series were established in the area surveyed.
