    摘要:

    以江苏省如皋市为例,在收集第二次土壤普查资料和已有的研究成果基础上,经过野外土壤观察和调查、土壤基本理化性质和微量元素性质分析,进行了该市土系划分及其生产性能和生态环境特征的研究。研究确定了土系划分的原则和依据、特征土层等,划分出9个土系。各土系土壤基本理化和微量元素性质的差异很好地验证了土系划分的可靠性。各土系在颗粒组成、化学性质、养分性质、微量元素含量等方面均具有显著差异,反映出各土系独特的生产性能和生态环境特征。

    Abstract:

    Soil series is the basement of the soil taxonomy and also a bridge connected with their productivity and eco-environmental evaluation, Therefore, they are of great theoretical and practical significance to soil classification and its application. On the basis of the data collected during of the second national soil survey and ongoing researches, through field observation and soil investigation of and analyses for soil physical and chemical properties and trace elements in Rugao County, Jiangsu Province, soils of the county were classified by series and their productivity and eco-environmental features studied. In line with principles, basis and diagnostic soil horizons for soil classification set in the study, the soils of the county were sorted into 9 soil series. The differences between the series in basic soil physical and chemical properties and trace elements validated reliability of the classification methods. The differences between various series were significant differences in particle size compositions, chemical properties, nutrient properties, and trace elements reflecting that each soil series has its own unique productivity and eco-environmental characteristics.
