Paper title：Research on Establishing a Farmland Quality Evaluation System Based on a Minimum Data Set Paper abstract：Establishing a cultivated land quality evaluation system that minimizes loss of existing information is crucial for guiding agricultural development, planning farmland management, and ensuring food security. This study adopts Principal Component Analysis (PCA) and the Entropy Weight Method (EWM) to construct the Total Data Set (TDS). PCA is utilized to determine the Minimum Data Set (MDS), while PCA and EWM are applied to establish indicator weights and calculate the soil cultivated quality index (SQI). The results indicate that by comparing the cultivated land quality results from PCA and EWM, it is concluded that the MDS with weights determined by PCA exhibits better consistency with TDS and higher accuracy in interpolation results. The mean and standard deviation values are extremely close (0.667 and 0.680, 0.063 and 0.074), indicating strong feasibility for replacing TDS with MDS. This study area generally exhibits a higher-cultivated quality index in the northeast and west, while the south, north, and central regions have poorer soil cultivated land quality. The average SQI is approximately 0.6, indicating above-average soil quality. Areas with better soil quality include Fenghuang Town, Dawan Town, and Pingyang Town, while poorer soil quality is found in Liangtang Township, Qiaogong Town, Qianjiang Town, Shiling Town, and Taodeng Town. Combining the weights reveals that the indicators significantly contribute to the evaluation results of cultivated land quality: effective soil layer thickness, topsoil depth, topographic location, topsoil texture, pH, total nitrogen (TN), and available phosphorus (AP). During cultivation, protective measures should be tailored to local conditions, taking into account terrain, elevation, acidification, and nutrient status. The results provide a scientific basis for evaluating and improving the quality of cultivated land in Guangxi's sugarcane-growing regions. Paper type：journal article Tutor: HuKelin
