| 摘 要： | 在分析紫色土肥力特征及其变化规律的基础上，运用Ｆｕｚｚｙ综合评判法，借助电子计算机，对四川省南充地区１９个紫色土土种的肥力状况进行评价，划分出紫色土的肥力等级，其结果表达为各土种对于不同肥力等级的隶属程度，反映土壤肥力分级的模糊性特点，评价的准确性也有所提高。

| Abstract: | n this paper, on the basis of the systematic analysis of the fertility characteristics and variational regularity, the fertility grades of 19 species of purple soil in Nanchong Region, Sichuan Province, are analysed and evaluated with fuzzy set method. The result of evaluation is an expression of the degree of belonging of the soil species to each of the discerned fertility grades. It shows that this new method is promising for further development and application in the field of soil fertility evaluation. |
