| 摘 要： | 此文选择了影响土壤养分的主要因素：全氮、有机质、速效钾、速效磷及微量元素有效锌和有效硼6个指标，用模糊数学的方法确定其隶属度函数并进行处理，运用“专家评分系统”确定各指标的权重，根据分析结果对6个县（区）的土壤养分综合状况进行模糊评判。结果表明，所分析的6个县（区）贵池和庐江地区土壤综合养分水平属于二级，较高水平；肥东、无为和居巢地区属于三级，中等水平；明光则属于四级，较低水平。同时应用指数和法与之比较，发现二者评价结果完全一致，均可用作土壤养分水平的综合评价。

| Abstract: | This paper chosen the main influence factors of soil nutrients including total nitrogen,organic matter,available phosphorus,available potassium and two kinds of trace elements zinc and boron these 6 indicators were selected to build model by fuzzy mathematical method to determine their membership function and process.The weight of each indicator was determined by the Expert Grading System.And Integrated Soil Nutrient Status of each county(district) could be calculated by using the result of fuzzy evaluation... |
