| 摘 要： | 通过对乌鲁木齐市水西沟乡、板房沟乡、四十户乡、青格达湖乡、安宁渠镇、永丰乡、六十户乡7个蔬菜基地土壤中重金属离子(镉、汞、砷、铜、铅、铬)含量进行检测,采用单因素决定和加权平均两种模糊数学模型对土壤重金属综合污染进行评价,分析结果表明,评价区域土壤环境中的6种重金属离子均在标准之内,土壤环境质量为一级,属于安全、清洁级水平,符合无公害蔬菜产地环境的要求。

| Abstract: | The result of a study on soil environmental quality by monitoring heav y metal (Hg, As, Pb, Cr, Cd, Cu) of vegetables was presented bases on Shuixigou country of Urumqi, Banfanggou country, Sishihu country, Anningqu town, Yongfeng country and liushihu country. Two kinds of fuzzy mathematics models of the singl e factor deciding model and weighted average model were adopted to evaluate the soil heavy metals comprehensive pollution. The analysis results indicate that th e content of 6 kinds of heavy metal ions in the regional soil environment which come from harmless vegetables bases on the Urumqi are within the standard, the s oil environmental quality is one grade,confirming to the level of safety and cle anliness. |
