摘要
通过对韩城南部乔子玄、卫东、龙亭花椒产区土壤取样分析,对照我国农业行业标准(NY5020-2001)规定的污染物控制指标及控制值,按照国家农业行业标准《农田土壤环境质量监测技术规范》推荐的单项污染指数和综合污染指数法,对韩城南部乔子玄、卫东、龙亭花椒产区土壤的6项污染指标进行了环境质量评价。结果表明:韩城南部花椒主产区土壤环境质量总体状况良好,处于"清洁"水平,达到"安全"等级,符合无公害农产品基地土壤环境质量的要求。
In terms of the agricultural sector standard of China,6 pollutants of soil were assessd and graded in the Zanthoxylum bungeanum distribution regions in 3 townships of southern Hancheng County with single pollution index method and comprehensive pollution index method.The results showed that the soil environment quality of Qiaozixuan,Weidong,and Longting was good,reaching the 'clean'and 'safe' levels.It totally meets the requirements of bio-rational production base stipulated by the central government.
