摘要: 通过对淮安市楚州区(M1)、清浦区(M2)、洪泽县(M3)等6个县(区)主要粮食作物(水稻、小麦、玉米)产地进行调查和分析测定,选取土壤和灌溉水重金属(Pb,Cd,Cr,As,Hg)为评价因子,采用模糊综合评价方法对产地环境质量进行综合评价。结果表明,评价等级均属Ⅰ级,土壤和灌溉水环境质量均达到清洁水平,可以考虑发展绿色食品,但是考虑各县(区)条件存在的差异,发展适宜的粮食产品还需进一步分析。

Abstract: Environmental quality of major food crops (rice, wheat and corn) producing areas were analyzed in Huai'an City, including Chuzhou District (M1), Qingpu District (M2), Hongze County (M3) and other 3 districts (counties), using fuzzy comprehensive evaluation method, and the contents of heavy metals (Pb, Cd, Cr, As, Hg) in soil and irrigation water in these areas were selected as evaluation factors. The result showed that the evaluation grades were classified into classⅠ, indicating the environmental quality of the soil and irrigation water reached the level of cleanness, which was quite necessary for the development of green food in these areas. Considering the existence of differences among counties and districts, the development of appropriate food products needs further analysis.

Key words: food crops producing areas, soil, irrigation water, heavy metals, fuzzy comprehensive evaluation
