摘要
通过对农业用地土壤中镉、铜、铅等重金属的污染情况进行初步调查分析,了解到污染因素主要是饲养所用的畜禽饲料转化为粪便作为肥料施用所致。因此,应积极采取有效措施对饲养所用的畜禽饲料进行严格监控,以综合防治农业用地土壤的重金属污染。
Through preliminary investigating the cadmium, copper, lead and other heavy metals soil of agricultural land in Qiannan area and then analyzing the pollution situation of these heavy met- als, this paper finds out that the main reason for pollution is that the fodder for livestock has poured in- to the soil after changing into the faeces. Therefore, effective measures should be adopted to strictly monitor the fodder for livestock in order to synthetically prevent and cure the pollution of heavy metals in soil of agricultural land.
