Abstract: Based on the data related to agricultural green development in Heilongjiang Province from2009 to 2018,the weights were calculated using the entropy weight method and combined with the gray correlation method to construct a new model to analyze the agricultural green development level in Heilongjiang Province.The results showed that the overall level of agricultural green development in Heilongjiang Province had shown an upward trend from 2009 to 2018.Among them,the greening of production base and the greening of agricultural output increased,and the greening of agricultural production showed a trend of first decreasing and then increasing.The main factors affecting the green development level of Heilongjiang agriculture were the disaster area,the intensity of fertilizer used,and the number of green food processing enterprised.In order to continue to increase the supply of green and high-quality agricultural products in the future and ensure the national food quality and quantity safety for a long time,we must focus on strengthening the ecological conservation of agricultural production bases,improving the efficiency of agricultural production processes,and consolidating the foundation of agricultural green industry development.
