| 摘 要： | 本文应用单个土体、聚合土体、土壤景观的概念进行系统分析,研究了长江三角洲淤泥土土层铁的活化度。研究表明,其A层因渍水耕作和施肥,使铁活化度大幅度增高,以土壤剖面发生学论证了土层对称性破缺的耗散结构。由于土壤是非均质体,而且淤泥土土层有先天不均一性,所以,传统土壤学根据以单个土体的分析结果代表整体特征的研究方法是不全面的。

| Abstract: | Systematic analysis by the concepts of pedon polypedon and landscape was used for the study of soil horizontal iron activation in puddled soils in the area of Changtiang River delta. The results indicate that the degree of iron activation are greatly increased in the A horizon of the soil due to water tillage and manuring, therefore the dissipative structure of system's symmetry breaking are proved on the point of soil profile development.The soil is an anisotropic body, soil properties determined depend on pedon or typical profile only is insufficient. |
