Abstract

The In the context of China's rural revitalization, this paper uses the random forest intelligent evaluation method to evaluate the development level of new urbanization and agricultural modernization in Anhui Province, and uses the synergistic evaluation method to evaluate the coordinated development of new urbanization and agricultural modernization. Based on the establishment of new urbanization evaluation index and agricultural modernization evaluation index system, this paper builds an evaluation model based on random forest intelligent algorithm on the open source software R language platform. Selecting the corresponding index data of each city in Anhui Province from 2011 to 2016, and classify the new urbanization evaluation index and agricultural modernization evaluation index into high, high, medium and low. The results show that the cities with a higher level of new urbanization are Hefei, Wuhu, Tongling and Huangshan. The lower cities are Bozhou, Suzhou, Fuyang, Huainan, and Lu'an. The evaluation results of the new urbanization level of cities in Anhui Province from 2011 to 2016 showed an overall upward trend over time; In 2016, Huainan City made significant progress in the development of agricultural modernization, jumping to the first place in the province. From 2011 to 2016, the city with the largest increase in the evaluation value of the development level of agricultural modernization in Anhui Province is Huainan City, with an increase of 0.946, the city with the highest growth rate is Anqing City, with a growth rate of 45.76%; The city with the smallest increase in the evaluation value of the development level of agricultural modernization is Ma'anshan City, whose value is 0.133, with an increase of 45.76%,  And the city with the lowest growth rate is Ma'anshan City, with a growth rate of 5.67%. The results of the "two modernizations" collaborative evaluation show that the areas with high levels of coordinated development of new urbanization and agricultural modernization in Anhui Province are concentrated in the central and eastern parts of Anhui Province, mainly including Hefei, Wuhu, Chuzhou, Ma'anshan and Bengbu. The areas with low levels of coordinated development of new urbanization and agricultural modernization in Anhui Province are concentrated in the southwest, mainly including Tongling, Anqing, Chizhou, and Huangshan. The remaining municipalities in Anhui Province are areas with the middle level of coordinated development of new urbanization and agricultural modernization, mainly including Huainan City, Huaibei City, Fuyang City, Xuancheng City, Suzhou City, Bozhou City and Lu'an City.
