Soil quality evaluation method and device based on grey correlation-TOPSIS, terminal and medium

The invention discloses a gray correlation-TOPSIS-based soil quality evaluation method, device, terminal and equipment, and the method comprises the steps: obtaining a soil quality evaluation initial index, building a minimum soil quality evaluation index system, combining gray correlation with a TOPSIS analysis method, building a gray-TOPSIS multi-target evaluation model, and carrying out the gray correlation-TOPSIS multi-target evaluation. And the setting of preference degree parameters by decision makers is improved, and the subjectivity of the gray-TOPSIS multi-target evaluation model is reduced. Therefore, according to the embodiment of the invention, the actual distance of the soil index in the multi-dimensional space and the correlation degree of the soil index in shape change can be comprehensively considered, and the soil quality evaluation accuracy of the gray-TOPSIS multi-target evaluation model is improved. 本发明公开了一种基于灰色关联-TOPSIS的土壤质量评价方法、装置、终端及设备，所述方法通过获取土壤质量评价初始指标，建立最小土壤质量评价指标体系，将灰色关联和TOPSIS分析方法相
