摘　　要：针对现有的耕作部件在天然草地作业时存在一定的局限性,缺少草地作业适用性综合评价方式和专用草地改良耕作部件作业效果评价体系的问题,采用变异系数法和线性加权法对各评价指标权重和耕作部件天然草地作业适用性综合评价模型进行研究;采用田间试验方法对耕作部件天然草地作业适用性综合评价模型进行验证。结果表明:基于牵引力、地表翻垡率和土壤扰动系数3个指标构建的耕作部件天然草地作业适用性综合评价模型,能有效评估耕作部件的天然草地作业适用性,应用该模型对不同耕作部件的作业效果进行综合评价,与现有的研究结果相符,模型具有可行性,该模型为耕作部件在天然草地作业中的适用性综合评价提供了一种更为便捷的方法。In view of the limitations of the current tllage components in natural grassland operation and the lack of comprehensive evaluation method for its applicability in grassland operations and the evaluation system for the operation effect of special grassland improvement tillage components,the coefficient of variation method and linear weighting method were adopted to study the weight of each evaluation index.A comprehensive evaluation model was constructed for the applicability of natural grassland operation of tillage components,and then field tests were conducted to verify the comprehensive evaluation model.The results showed that:The comprehensive evaluation model proposed in this study was constructed based on three indexes,e.g.,traction force,surface turning rate and soil disturbance coefficient,which could effectively evaluate the applicability of tllage components in natural grassland operation.The operational effects of different tillage components evaluated by the new model in this study were consistent with the results of existing research,which confirmed the feasibility of the comprehensive evaluation model.In conclusion,this study provided a more convenient method for the comprehensive evaluation of the applicability of tillage components in natural grassland operation.
