    摘要:

    城乡交错区的工业发展可能导致土壤重金属积累,并威胁食品安全。本文以无锡典型工业型城乡交错区为例,利用地统计学变异函数研究了农业土壤全量Zn和DTPA-Zn的空间变异特征,并分析了其影响因素。结果表明:人类活动明显增加了土壤的含Zn量,研究区土壤全量Zn具有强烈的空间自相关性,其空间变异主要与工业活动有关,土地利用对它没有影响;土壤全量Zn在工厂分布区附近较高,其他地区较低。土壤DTPA-Zn变异性大于全量Zn,具有中等的空间自相关性,其空间变异与工厂无明显关系,但土地利用对它影响较大,菜地DTPA-Zn含量明显高于水稻田。

    Abstract:

    In peri-urban areas,industrialization may lead to accumulation of heavy metals in the soil,threatening food safety.In this paper,the concentrations of total Zn and DTPA-Zn in soil were determined in an area of 8 km2 in a typical industrialized peri-urban region of Wuxi.Geostatistical theory was used to characterize spatial variability of total Zn and DTPA-Zn in soil and its affecting factors were discussed.Results showed that concentrations of total Zn in the soil exhibited strong spatial dependence,and the spatial variation was induced by industries,while effect of land use on total Zn in the soil was not found.High concentrations of total Zn were found in the soil near to industries. Concentrations of DTPA-Zn in soil exhibited moderate spatial dependence,and the spatial variation was not positively related to industries,but was greatly affected by land use pattern.And the concentrations of DTPA-Zn were significant higher in vegetable fields than in paddy fields.
