基于模糊相似优先比方法的新疆不同植棉区细绒棉纤维品质评估

Quality Evaluation of Fine Staple Cotton Fiber in Different Cotton Planting Areas in Xinjiang with Fuzzy Similarity Preference Ratio Method

选取2017年棉花目标价格改革补贴与质量挂钩试点县的棉花主要指标作为样本,利用Topsis法对试点县的棉花品质进行了综合评价,结果显示玛纳斯县棉花的综合指标最好。利用模糊相似优先比方法,将新疆12个棉花产区棉花指标与玛纳斯县棉花的综合指标作比较。结果表明,石河子的棉花品质最相似,而喀什的棉花程度相似程度最低。从顺序排列来看,北疆棉花品质接近程度普遍高于东疆和南疆地区,新疆各地州棉花品质指标存在差异。

The main indicators of cotton in pilot counties where subsidies were granted for cotton target price reform based on quality in 2017 were selected as samples,the cotton quality in the pilot counties was evaluated with Topsis method comprehensively,and the results show that Manas cotton achieved the best comprehensive indicators.Comparison was conducted between cotton indicators in 12 cotton producing areas in Xinjiang with the comprehensive indicators of Manas cotton with the fuzzy similarity preference ratio method.The results showed that Shihezi cotton is most similar to Manas cotton,while Kashgar cotton is least similar.In terms of seriation,the proximity of cotton quality in Northern Xinjiang is generally higher than that in Southern Xinjiang and Eastern Xinjiang,and differences in cotton quality indicators exist in different prefectures of Xinjiang.
