摘　　要：通过对在土壤质量评价中关于确定评价因素鉴定指标、单因素评价以及综合评价等关键性问题的综合分析,依据土壤质量评价中存在模糊性特点,利用模糊数学建立土壤质量单因素评价和综合评价模型的思想与方法,对恩施州12种农业土壤质量进行综合评价,结果表明模糊数学方法在土壤质量综合评价中是一种较为理想的方法,评价结果基本符合土壤实际.By integrated analysis of pivotal problem such as defining diagnostic criteria of evaluation factors, single factor evaluation and integrated evaluation in soil quality revaluation, and make use of the thought and method for establishing single factor evaluation and integrated revaluation models by applying fuzzy mathematics, 12 agricultural soil of Enshi Autonomous Prefecture were synthetically appraised. The result showed that fuzzy mathematics was an ideal method. This result accords with the actual situation of fact.
