Abstract: By studying the connotation of cultivated land quality in the new era, this paper analyzes the problems in the existing evaluation index system established by regulations, standards, and research results. On this basis, the cultivated land protection policy is improved as guidance. The demand for fine management of cultivated land is the result orientation, and the connotation of cultivated land quality in the new era serves as the starting point. The newly proposed system combines the essence of the existing index system and reallife local situations. The evaluation index system of cultivated land quality of Guanzhong Weihe Plain in Shaanxi Province includes 4 criterion layers, which are soil quality, management and protection quality, utilization quality, and ecological quality, and 13 index layers. The weight of soil quality in the standard layer is 0.4, the weight of management and protection quality is 0.3, the weight of utilization quality is 0.2, and the weight of ecological quality is 0.1. The weight of each evaluation index, index grading value, and factor reference score are determined, providing new ideas and methods for the quality evaluation of main grain producing areas in Shaanxi Province and even the whole country.
