| 摘 要： | 从上海全市214个土壤剖面样品的13个元素的背景含量,探讨了pH、有机质和石灰反应对其之影响,并对几个主要土类、亚类和土属进行了详细阐述。调查表明,上海表层土壤中,pH和有机质都与Mn、Hg、Se呈中度相关:水稻土、潮土和盐土等3个主要土类之间的pH值、有机质含量都有极显著差异,一些相应元素也有显著差异:随石灰反应的强烈,含Cu量增加,而Zn、Cr、F、Se的含量减少。

| Abstract: | Background value of thirteen elements from 214 soil profile samples were survey and the effects of pH, or- ganic matter and lime reaction on them were described. The result of survey showed that pH and organic mat- ter were medium correlated with Mn, Hg and Se. the pH value and organic matter in rice soil, moist soil and salty soil and their corresponding elements were different obviously, and the strong reaction of lime did increase the content of Cu and decrease the content of Zn, Cr, F and Se. |
