摘  要：
[目的]研究不同土地利用方式下城市土壤铁的分布特征,为土壤重金属和有机污染物的治理提供理论依据。[方法]在南京市主城区采集具有相似母质的道路、绿地和菜地土壤剖面样品,测定全铁、游离铁和活性铁及相关指标,并进行统计分析和绘制剖面分布图,探讨不同土地利用方式下城市土壤铁的分布特征及其原因。[结果]城市不同土地利用均导致土壤全铁和游离铁减少,而活性铁增加;从垂直分布来看,不同土地利用方式下各形态铁和表征铁老化/活化的指标的极高值出现不同的土壤深度范围:道路土壤和绿地土壤较深,菜地土壤较浅。[结论]城市土壤游离铁含量降低、活性铁含量升高及峰值出现位置与土地利用方式有关,对重金属和有机污染物的迁移转化意义重大。

摘  要：
[Objective] The research aimed to study the distribution characteristics of soil iron Species in Urban Soils under different land-use patterns and provide the scientific basis for remediation of heavy metal and organic pollutants.[Method] The sample of soil section on the road,greenbelt and vegetable plot with the same parent material was screened in urban Nanjing to measure Fet,Fed and Feo and related index.Their statistical analysis was made and the profile distribution picture was drawn,and the distribution characteristics of soil iron in city under different land use patterns and their reasons were discussed.[Result] The different land use patterns in city induced the decrease of Fet and Fed in soil,but the Feo was increased.From the vertical distribution of aging or activation indexes of iron and iron species,under the different land use patterns,the appeared extreme high value had different range of soil depth,which existed at the deeper position of road soil and greenbelt soil and also existed at the shallower position of vegetable plot soil.[Conclusion] The decrease of free iron content,the increase of the active iron content in soil in city and the position of appeared peak value related to land use patterns,which had the great significance on the migration and transformation of heavy metal and organic pollutants.
