摘　　要：为了揭示芜湖市烟草种植区土壤肥力质量的空间变化规律,运用Fuzzy综合评判法,对芜湖市湾沚镇烟草种植基地土壤的肥力状况进行研究。共选取7个理化指标(pH、有机质、全氮、全磷、速效磷、速效钾、有效钾)对土壤养分状况进行了综合评价。结果表明:56.4%的土壤样品土壤综合肥力指数(integrated fertility index,IFI)达到了高等级,平均值为0.86,位于较高和中等级别的土壤样品所占的比例均为12.7%,其IFI平均值为0.70和0.58,二者相差不大,基本上能够满足烟草生长所需的肥力。18.2%的土壤样品位于较低的等级,IFI平均值仅为0.52,需要对其采取有针对性的措施来提高其综合肥力。The objective of this study was to explore the spatial variability of soil fertility quality, so the methodof Fuzzy was used to analyze the contention of soil fertility in the tobacco base in Sanyuan Town of Wuhu City.Seven indicators were selected： pH, organic matter, total nitrogen, total phosphorus, rapidly availablephosphorus, rapidly available potassium, and available potassium. It can be concluded that the IFI of 56.4%soil samples reached the highest level, and the average value was 0.86. The percent of the higher and middlelevel of soil samples were both 12.7%. Correspond, the average value of IFI were 0.70 and 0.58. The both levelcan satisfied the fertility need of tobacco. 18.2% of soil samples were in the lowest level, and the average valuewas 0.52. The situation of fertility should beimproved in order toincreasetheamount and quality of tobacco.
