摘要：
Agricultural modernization is important for rural construction, social economy, and civilization development. Based on the statistical data of the Qinghai-Tibet Plateau from 1990 to 2017, we built a comprehensive index system with agricultural modernization as the primary index, agricultural input level, agricultural output level, and sustainable agricultural development level as the secondary indexes, and then obtained the weight of each index through the entropy value method. Finally, the agricultural modernization index and driving factors on the Qinghai-Tibet Plateau were calculated. The results showed that: (1) from 1990 to 2017, the agricultural modernization level in the study area is generally low (with the value of 0.15) compared with the average level of China, showing an increasing trend; (2) the counties of relatively high level of agricultural modernization such as Dege, Huangzhong, Bailang, and Langkazi are scattered in the northern, southeastern and southern edges, and the YLN (Yarlung Zangbo River, Nyangqu River and Lhasa River) region of the Qinghai-Tibet Plateau; (3) electricity consumption per unit cultivated area, effective irrigation rate and land productivity had the greatest effects on the agricultural modernization level on the plateau, with the contribution degrees being 13%, 12% and 11%, respectively. © 2022, Science Press.
