利用2011年云南省烟叶工商交接等级质量监督检查数据对云南省烟叶工商交接7个主收等级（B2F、B3F、C2F、C3F、C4F、X2F和X3F）的等级质量（用等级合格率表示）与等级纯度、混级个数以及混高、混低、混杂、混部位和混V+GY比例7个影响因素进行了相关性分析。结果表明，7个主收等级的等级合格率主要受等级纯度、混低、混杂、混V+GY比例和混级个数的影响，各影响因素对烟叶等级质量的影响趋于等级纯度>混低>混杂>混V+GY>混级个数>混部位>混高。提高烟叶等级纯度，控制烟叶收购中的混低、混杂、混V+GY和中部主收等级（C2F、C3F和C4F）混部位现象是提高烟叶质量的关键。

Data from supervision of tobacco leaf grading quality in Yunan in 2011 were used to analyze correlation between grade quality (evaluated by qualified rate) of 7 major purchasing grades (B2F, B3F, C2F, C3F, C4F, X2F and X3F) and influencing factors. Result indicated that grade quality of 7 major purchasing-grades was mainly influenced by grade purity, confused low grades, variegated leaves, mixed (V+GY) and mixed-grades. The influence of 7 factors exhibited the tendency:grade purity>confused low grades>variegated leaves>mixed (V+GY)>mixed-grades>mixed stalk positions>mixed high grades. Improving grade purity is the most effective way for further improving grade quality in Yunan. Tobacco leaf grade standard should be strictly kept in tobacco leaf purchasing. Confused low grades, variegated leaves, V+GY and stalk positions should be effectively controlled.
