摘要
以地木耳为材料，现场监测兰州市大气污染。选择含硫量、伤害面积、pH值为指标，同时以例行监测的大气环境质量综合指数为参照，对每项指标作定量化计算，确定其分级标准．用模糊数学方法对大气环境质量作综合评判。结果表明，地木耳多指标模糊综合评判法与综合指数法一致，具较高的可靠性。
Ambient exposing was conducted to bioindicate air pollution around Lanzhou citywith Nostoc commune.The sulphur content,area of death,pH value in Nostoc communewere chosen to evaluate air quality using quantified method and fuzzy model.The resultsshow that the multiple fuzzy model correlated significontly with the multiple indexmethod,and suggest that it is feasible and reliable.
