摘要
对乌鲁木齐市蔬菜生产基地的大气、灌溉水、土壤等环境要素,以GB/T18407.1-2001《农产品安全质量———无公害蔬菜产地环境要求》为标准,采用单因子指数法及综合污染指数法进行评价。结果表明:乌鲁木齐市蔬菜生产基地的环境质量符合规定的范围,但部分监测点的大气环境质量中的TSP单因子污染指数为1.1>1,表明已经受到污染(但TSP不是严控指标),部分土壤环境质量中镉的单因子污染指数>1,达到1.12,属于轻度污染。但多因子综合污染指数均<1,只要在生产中采取一定的防治措施,该基地仍可作为无公害蔬菜的生产基地。
Environmental quality of atmosphere, soil and irrigation water in vegetables producing areas of Urumqi is evaluated by the single factor index method and synthesized index method and standards such as GB/T18407.1-2001《Safe quantities in the agricultural product environment requests of the non-polluted vegetables》.The results show that the quality of environment is all within the scope of standard, but TSP, chrome contents of individual areas comes to a light degree which exceeds the scope. For example, the TSP content is more than 1 and reaches 1.1; the chrome single content in Daxigou is more than one and reaches 1.12.But the synthesis contaminative indexes are less than 1. If we take measures during the producing vegetables, it is still a base of non-polluted vegetables.
