摘要 在DPS统计软件的支持下,用灰色关联分析确定产量与各因子之间的灰色关联值,再结合专家的意见确定各因子的权重,用指数和法确定其得分,然后用聚类分析进行耕地适应性评价,评价出适宜耕地等级。 Choose 2 247 units of cultivated land in the Yuli of Xinjiang were used to analyze the relation between crop yield and its relevant factors with the software in the DPS and the gray relation method. The gray relation value was made and the suitability of cultivated land was evaluated for the grade of cultivated land.
