| 摘 要： | 在兰州—白银地区,由于各种复杂的地质作用及人类活动综合影响,农作物所需营养元素及有毒、有害组分在区内表层土壤中的分布明显不均衡。以土壤地球化学测量中元素含量分布为主要依据,在分析兰州—白银地区土壤污染现状、农作物所需有益元素丰缺现状的基础上,对区内农业土壤环境质量进行了评价,Cr、N i等重金属元素生态风险及富集污染强度、空间离散强度相对较弱,而Cd、Hg、Pb、Zn、Cu、As都极为离散。按环境的优劣划分了农业生态优质区(Ⅰ类)、一般区(Ⅱ类)、不良区(Ⅲ类)三个等级,并提出了土壤培肥原则和修复措施。

| Abstract: | In Lanzhou-Baiyin area,the composite effects of various natural and geological actions and human activities have resulted in obvious nonequilibrium in the distribution of nutritional elements as well as toxic and harmful components in the surface layer soils.A quality assessment of agricultural soil in this area was conducted based on the content distribution of elements determined by soil-dominant multi-media geochemical measurement and the investigation of current situation of soil pollution together with... |
