应用凉州区县域耕地资源管理系统(CLRMIS)，考虑影响凉州区小麦甘育3号生长的主要因子，构建层次模型，结合测土配方数据建立的农业生产因子数据库，拟合出每个因子的隶属函数，运用累计曲线法分析当前模型下春小麦甘育3号应用适宜性分区。结果表明，该模型下春小麦甘育3号总体在凉州区灌区全部适宜。其中高度适宜等级面积28 715.98 hm2，占耕地面积的19.58%；适宜等级面积84 509.46 hm2，占耕地面积57.62%；勉强适宜等级面积 33 434.03 hm2，占耕地面积22.80%。

Using liangzhou district county cultivated land resources management system (CLRMIS)， considering the main factors affecting the growth of wheat Ganyu 3 in Liangzhou District， a hierarchical model was constructed. Based on the database of agricultural production factors， the membership functions of each factor were fitted， and the application suitability zoning of spring wheat Ganyu 3 under the current model was analyzed by cumulative curve method. The results showed that spring wheat Ganyu 3 under this model was suitable for Liangzhou Irrigation District as a whole. Among them， 28 715.98 hm2 is highly suitable grade area， accounting for 19.58% of cultivated land area； 84 509.46 hm2 is suitable grade area， accounting for 57.62% of cultivated land area； 33 434.03 hm2 is barely suitable grade area， accounting for 22.80% of cultivated land area.
