在土壤流失的过程中往往伴随着化学元素的迁移,由此引起元素的分散或富集。元素在土壤中的迁移是由于受了能量作用的结果,其中包括水蚀、风蚀和重力侵蚀。其迁移能力的大小取决于元素的化学性质:有的迁移能力强,如钾、钠、钙、镁、铝和铁;有的迁移能力弱,如钛、锇、铂。由于元素的迁移,土壤化学组成也随之改变,这种变化有时是很微小的。由于分析测试手段的限制,目前人们对因水土流失引起的元素迁移的研究仅限于三个主要的植物营养元素——氮、磷、钾。本文采用电感耦合等离子体发射光谱法同时测定土壤中9种元素的含量。样品经酸溶解后,不需加任何试剂,即可由仪器进行测定,并由打字机打印出各元素的含量。电感耦合等离子体发射光谱分析技术简称ICP—AES,是用电感耦合等离子体作为激发光 In the process of soil loss is often accompanied by the migration of chemical elements, thereby causing the dispersion or enrichment of elements. Element migration in soil is due to the effects of energy, including water, wind and gravity erosion. The size of its migration depends on the chemical nature of the element: some migratory ability, such as potassium, sodium, calcium, magnesium, aluminum and iron; and some migratory ability is weak, such as titanium, osmium, platinum. Due to the migration of elements, the chemical composition of the soil changes accordingly, and this change is sometimes very small. Due to the limitation of analytical testing methods, the current research on the element migration caused by soil erosion is limited to three main plant nutrient elements - nitrogen, phosphorus and potassium. In this paper, inductively coupled plasma atomic emission spectrometry was used to determine the content of nine elements in soil simultaneously. Samples dissolved by acid, without any reagents, can be measured by the instrument, and by typewriter print out the content of each element. Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES), abbreviated as ICP-AES, uses inductively coupled plasma as an excitation light
