Yunnan is a large province of modern agriculture with plateau characteristics. Accelerating the green development of agriculture is an important link to promote the high quality development of agriculture in Yunnan Province. By constructing the comprehensive evaluation index system of agricultural green development in Yunnan Province, the agricultural green development level in the study area from 2011 to 2021 was estimated, and the trend characteristics and regional differences of agricultural green development in Yunnan Province were revealed.Resource conservation, environmental friendliness, ecological conservation, quality and high efficiency were set as four first-level indicators to measure and evaluate the agricultural green development level of Yunnan Province, and 13 second-level indicators were set up on the basis of the first-level indicators. Through data collection, collation and analysis of the agricultural green development level of Yunnan Province, the results show that the agricultural green development level of Yunnan Province is on the rise. The comprehensive score of agricultural green development of cities and municipalities represented by Qujing, Chuxiong, Wenshan and Dali is at the leading level, while the agricultural green development level of Dehong and Deqing is relatively low, with a large space for future development.In the first index, the scores of quality efficiency, resource saving and environmental friendliness are relatively high, while the scores of ecological conservation are relatively low. Therefore, suggestions that Yunnan Province should focus on ecological environmental protection in the next step, and consider development countermeasures from the three aspects of government policy, environmental governance and green standard formulation to form a joint force to promote the better development of agricultural green in Yunnan Province are put forward.
