ABSTRACT

With the help of the Chinese government, China's Saihanba Forest Farm has recovered from the desert and has now become an eco-friendly green farm with stable sand control function. After more than half a century of struggle, the largest artificial forest in the world was built in Saihanba. We expanded the afforestation of 1.12 million mu and planted more than 400 million trees. The builders created a green ocean on the plateau wasteland 400 kilometers north of Beijing. Therefore, through the data collection and analysis of Saihanba, this paper establishes the ecological environment impact assessment model of Saihanba based on the gray target model. According to the evaluation index and bull's eye value, using the data of plant abundance, plant coverage and total number of animals from 1966 to 2021, the environmental impact before and after the restoration of Saihanba is quantitatively analyzed by using the comprehensive index method.
