摘要
以西部矿业城市金昌市为对象,测定不同用地类型的土壤中重金属的含量,运用双权重因子模糊综合模型对土壤污染进行评价.结果表明,居住用地为Ⅲ级轻污染,公共设施用地为Ⅳ级中污染,工业用地、道路广场用地、绿地以及农田为Ⅴ级重污染;在各用地类型中镍和钴的污染程度较高.长期的冶炼生产、沙尘暴、水土流失及酸雨等,更加重了重金属的污染程度,土壤重金属污染已成为制约生态环境健康的瓶颈,采取合理防治措施迫在眉睫.
This paper studies the mining city--Jinchang in the western area of China. The method of fuzzy mathematics is used to evaluate the characteristics of heavy metal pollution in urban soil based on different land-use types. The results show that, the ranking quality for soils from the habitation are Ⅲ, the public infrastructure land are Ⅳ , the industry land, the roads and squares Band, the agricultural land and the city greenbelt are Ⅴ , Ni and Co are highly contaminative. Synergistic effect of sand and dust storm, soil and water loss and acid rain strengthen the pollution degree, the serious pollution is the ＂bottle-neck＂ problem in the sustainable ecological development, so that it is high time to take measures to prevent heavy metal pollution.
