| 摘 要： | 针对蔬菜产地环境质量问题,本研究以秦皇岛市14个重点蔬菜基地为研究对象,依我国农业部无公害蔬菜产地环境标准和绿色蔬菜产地环境标准,采用单项污染指数法和综合指数法对蔬菜产地土壤环境进行了评价与分析。结果表明:秦皇岛市蔬菜产地土壤环境质量整体上符合我国无公害蔬菜产地环境质量要求,但各蔬菜基地土壤肥力较低,且部分基地土壤Hg、Pb、Cr含量超过绿色蔬菜产地标准,不利于绿色蔬菜生产,应采取有效措施改进。

| Abstract: | Basing upon the environment standards for pollution-free vegetable producing areas and the environment standards for green vegetable producing areas,this paper studies the soil environment quality of the 14 important vegetable producing bases in the city of Qinhuangdao,following the single-index and multiindex models.The results show that the soil quality of these bases satisfies the national standards for pollution-free producing areas.However,the soil fertility thereof is rather low,and the density of Hg and Cr of the soil in some bases exceeds the national standards for green vegetable producing areas,which hinders the production of green vegetables.Accordingly effective measures should be taken to improve the situation. |
