江西南昌-樟树地区农业土壤环境质量评价

在研究区内,由于各种自然地质作用及人类活动综合影响,使作物营养有益元素及有毒、有害组分在区内表层土壤中的分布存在明显的不均衡性.以土壤中元素的含量分布为主要依据,在分析南昌-樟树地区土壤污染现状、农作物营养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,并按环境质量的优劣划分了A、B、C、D共4个等级.

THE EVALUATION OF THE AGRICULTURAL SOIL ENVIRONMENT QUALITY OF NANCHANG-ZHANGSHU AREA, JIANGXI PROVINCE

In the study area, the composite effects of various natural and geological actions and human activities have resulted in the obvious nonequilibrium of the distribution of nutritional elements as well as toxic and harmful components in the surface layer soil. With the distribution of element contents in soil as the main data and on the basis of an analysis of the soil pollution situation and the enrichment or deficiency of the nutritional and beneficial elements in crops of Nanchang-Zhangshu area, this paper made an evaluation of the agricultural soil environment quality in this area, and classified the environment quality into four grades, which are in the worsening order A, B, C and D.
