本研究对烟台市优质苹果生产基地土壤养分和重金属Cd、Hg、As、Pb、Cr含量进行了分析并对土壤养分状况和环境质量状况进行了分级和评价.结果表明:烟台市优质苹果生产基地土壤养分含量评价为高等水平,土壤重金属含量均低于国家标准"农产品质量安全无公害水果产地环境要求(GB/T 18407.2-2001)"的限量要求,土壤环境质量评价为清洁水平,适宜发展出口苹果.但监测发现,烟台苹果产地土壤酸化比较严重,部分基地的重金属Cd含量已接近国家限量标准,建议加强土壤环境质量的监控和综合修复技术的研究,合理控制农业投入品的使用,最大程度地降低环境风险.%The monitoring and Evaluation on Environmental Quality of Yantai Export Apple Orchard were detected and analyzed in this study · while some classification and evaluation were given on the soil nutrient levels and environmental quality status. The results showed that the nutrients contents in apple orchard soil in Yantai city were in high level and the contents of heavy metals were lower than the limited requirements by the national standards “Safety qualification for agricultural product- environmental requirements for pollution -free fruit (GB/T 18407.2 -2001 )”. On the whole, the soil quality was evaluated to a standard of ‘cleanliness' and suitable for developing export apples. But on the other hand, the soil acidification and Cd pollution were still serious in Yantai apple orchard and metal Cd content was approaching to the national limited requirements in some apple production bases,which indicating that human life and production activities had caused soil pollution in some degrees. It is recommended to enhance environmental quality monitoring and comprehensive remediation research and control the use of agricultural inputs reasonably to effectively reduce the environmental risks.
