摘要:
以西安市不同灌溉类型的农田土壤为对象，研究重金属污染现状及其与灌溉类型的关系。结果表明，不同灌溉条件下的农田土壤重金属含量差异较大，沣惠渠灌区土壤重金属Cu，Zn，Cd，Pb平均含量最高，邓家村污水灌区次之，皂河水灌区、井灌区更次之，泾惠渠灌区土壤中的含量最低。Ni，Cr元素含量则以邓家村污水灌区最高，沣惠渠灌区、皂河水灌区、井灌区、泾惠渠灌区依次降低。从污染指数来看，沣惠渠灌区>邓家村污水灌区>井灌区>皂河水灌区>泾惠渠灌区。沣惠渠、邓家村、皂河灌区重金属主要来源于污水；井灌区重金属主要来源于霸桥热电厂和渭河电厂以及农家肥的施用等；而泾惠渠灌区各重金属受成土母质和成土因素的影响较大。
Abstract:
The pollution levels of heavy metals and the relations between they and irrigation types was studied in top soils of different irrigation types in Xi’an City.The results showed that the contents of heavy metals have great differences in the soils of different irrigated types.The maximum average contents of Cu, Zn, Cd, Pb were found in Fenghui Channel area, the medium ones were found in Dengjiacun area, the ones in Zaohe irrigated area and well irrigated area were lower, and the minimum ones were in Jinghui Channel area.Dengjiacun wastewater irrigated area had the highest contents of Ni and Cr.Fenghui Channel area, Zaohe irrigated area, well irrigated area and Jinghui Channel area gradually decline.The pollution indices of different irrigated areas was the order of Fenghui Channel>Dengjiacun wastewater irrigated area>well irrigated area>Zaohe irrigated area>Jinghui Channel area.The heavy metals in Fenghui Channel area, Dengjiacun wastewater irrigated area and Zaohe irrigated area root in wastewater.The soot from Baqiao Heat-electric works and Weihe electric works and the applications of farmhouse fertilizer were an important input of heavy metals in well irrigated area.The original materials in Jinghui Channel area primarily affected the contents of heavy metal.
