Today, 40% of the world's land is threatened by desertification, nearly 500000 square kilometers of land is turned into desert every year. Environmental protection is urgent. Saihanba National Forest Park in Hebei Province is a national nature reserve approved by the State Council. however, 20 years ago, the area was faced with increased desertification, soil erosion and loss of biodiversity. It is of great significance for ecological construction to study the influence of Saihanba forest farm construction on ecological environment. In this paper, the ecological environment impact assessment model of Saihanba forest farm is established, the environmental conditions before and after the restoration of Saihanba are compared and analyzed. First of all, this paper selects five indicators: the average gale days in typical years, CO2SC, PM2.5, forest coverage and terrestrial wild vertebrate species data, and uses the TOPSIS evaluation method based on AHP to establish assessment model to quantitatively evaluate the impact of Saihanba restoration on the environment. The analysis shows that with the restoration of Saihanba, the ecological environment in the area continues to improve, the forest coverage continues to increase, the average number of gale days continues to decrease, and the species of wild animals continue to improve.
