拜泉县上升乡绿色肉鹅食品产地环境质量综合评价研究

Comprehensive Evaluation of Environmental Quality for Organic Meat Goose Production in Shangsheng Township, Baiquan County

调查和测定了拜泉县上升乡进步小流域内的土壤养分、重金属以及水质pH值、氟化物、氰化物、重金属等的含量,并对土壤质量和水质量进行了分析和评价,以期为在实际生产中为绿色肉鹅食品的生产基地的选择提供理论依据和数据支撑。研究结果表明:本区域的土壤肥力高,为1等级别;土壤重金属含量均符合绿色食品产地的土壤环境质量标准,综合指数P综≤0.7,属于安全等级,达到了1级标准;水质量符合绿色食品产地环境质量中的禽畜用水质量的标准,水质单项污染指数均<1.0,综合污染指数≤0.5,水质量等级为1级。因此,在典型调查区域内,利用不同的土地利用类型推行肉鹅的放牧式散养模式,是发展寒地绿色肉鹅食品的理想场所。

The soil and water quality of Jinbu watershed in Shangsheng of Baiquan are analyzed to provide necessary basis and data support for a production base of organic meat goose.The soil parameters evaluated are the nutrients and heavy metal contents,and the water parameters evaluated are the pH value and the fluoride,cyanide and heavy metal contents.The results show that the soil in the region is in high fertility level of grade1.Heavy metal contents in the soil accord with the soil environmental quality standards for organic food production areas,the comprehensive pollution index P≤0.7,which is of grade 1.The water quality is suitable for poultry and livestock and complies with the environmental quality standards for organic food production areas,the single-item and comprehensive pollution indices is<1.0 and≤0.5,respectively,making the overall water quality grade 1.Goose farming based on grazing and free-range model could be promoted on different land use types.The typical survey area is an ideal location for the development of organic goose farming.
