科学准确地评价耕地质量是制定农业土地利用总体规划的基础。对玛纳斯河流域典型农田的土壤进行田间采样和室内分析化验，结合地下水埋深和土壤理化性质的调查数据，筛选土壤碱解氮、有效磷、速效钾、有机质含量、土壤pH值、总盐含量、地下水埋深7个指标，采用模糊数学方法，构建了耕地利用潜力评估模型。评估结果表明：研究区耕地处在缺氮、少磷、丰钾状态，以中潜力和中高潜力为主，占总面积的72.68%；高潜力和低潜力区面积较小，占研究区总面积的27.32%。该模型和评价方法可为流域土地利用及开发提供理论依据。

The quality evaluation of cultivated land is the foundation of the agricultural land use planning. Taking Manasi River Basin as the research object, the experiment was carried out whose data was analyzed with the fuzzy mathematics method. The land-use potential evalua-tion model was constructed based on soil organic matter, available nitrogen, available phosphorus, available potassium, pH value, total salt content and the depth of groundwater in Manasi desert oasis area. The results indicated the study area was in lack of nitrogen and phosphorus and abundant with potassium. The distribution map of land-use potentiality was made and indicated four grades areas. The secondary and third utilization potential area accounted for 72.67%of the total area, the highest and lowest potential area covered the area of 27.32%. The model and evaluation method can provide theoretical basis for land use and development.
