摘要
为研究银川市郊区农产品产地环境质量,按照《无公害食品产地环境质量调查规范》(NY/T5335-2006),采用调查与采样分析相结合的方法,对银川市郊区9个乡(镇)农产品产地环境空气、土壤和灌溉水质量进行了定点取样分析,在此基础上进行单因子污染指数法和综合污染指数法评价。结果表明,监测区环境空气SO2、NO2和氟化物的污染程度较轻,TSP含量相对较高,日均值最高达0.236mg/m3;土壤重金属含量地区间差异较大,变异系数在5.9%～244.4%,Pb的差异最小,Cr的变化最大;灌溉水水质良好。评价结果均符合《无公害食品大田作物产地环境条件》(NY5332-2006),银川市郊区适宜于发展无公害农产品种植基地。
In order to study environmental quality of the agricultural products producing areas in Yinchuan suburb,the air,soil and water quality in the agricultural products producing areas of nine towns in Yinchuan suburb were analyzed by the combined investigation and sampling method and then evaluated by single factor pollution index and composite pollution index according to Non-pollution Crop＇s Locality Environmental Quality Parameter（NY5332-2006）.As indicated by the results,the contamination degree of SO2,NO2 and fluoride in air was minor,while the content of TSP was higher with the maximum daily average of 0.236 mg/m3;the content of heavy metal in soil was greatly different in various districts,ranging from 5.9% to 244.4%,the discrepancy of Pb was the smallest,and the variation of Cr was the biggest and the quality of irrigation water wss good.Therefore,the results met the requirements of Non-pollution Field Crop＇s Locality Environmental Quality Parameter（NY5332-2006）,and the district was suitable for developing into non-pollution crop producing base.
