摘    要:本研究从生态学观点出发,根据土壤缺乏微量元素的临界值指标,探究了四川盆地土壤微量元素的生态类型,按其土壤供给有效态微量元素的丰缺程度,将本区土壤微量元素分为五种生态类型:严重缺乏、缺乏、适中、丰富和很丰富。统计结果表明,四川盆地各类土壤的微量元素生态类型特点为:有效硼含量很低,普遍严重缺硼;有效锌含量亦低,近半数土壤缺锌;多数土壤有效锰含量丰富,仅少部分土壤供锰不足;有效铜和铁的含量丰富。

关 键 词:土壤生态类型  微量元素丰缺度  四川盆地

Abstract:The characteristics of the trace element distribution in soils from Sichuan Basin was studied. The soils were divided into five ecotypes, namely, seriously deficient, deficient, moderate, rich and very rich, according to their available element contents and the critical deficiency values. The results showed that the most soils were seriously deficient in B, Zn deficiency was found in almost half of soils investigated, Mn deficiency was only related to a few soils and all soils were rich in Cu and Fe.
Keywords:soil ecotypes  trace element deficiency  Sichuan Basin
