Saihanba ecological area is a concentrated distribution area of natural vegetation drawn from the forest land under the jurisdiction of Hebei Saihanba mechanical forest farm. Through the construction of ecological area, Saihanba has realized the transformation from yellow sand, no birds and trees to green development. Therefore, the study of Saihanba ecological area has deep academic significance. However, scholars mostly start from the qualitative point of view on the effect of Saihanba forest ecosystem Nature Reserve. This paper first uses the analytic hierarchy process model (AHP) based on entropy weight method (EWM) to analyze the impact of Saihanba ecological area construction on the local environment from the qualitative and quantitative point of view. Based on this model, this paper makes a qualitative and quantitative evaluation on the effect of the model extended to the whole country, and demonstrates its impact on China's carbon neutralization effect. The model data shows that the Saihanba for ecological area construction plays a positive role in promoting the environment. The score shows that the environmental score of Saihanba in 2020 is 32 times that of the year before the implementation of ecological area, which fully demonstrates the effectiveness and importance of the Saihanba ecological protection model and is an important measure of China's green mountain strategy. In order to explore whether the Saihanba ecological protection model has popularization significance for the whole country, the cluster model is used for research and analysis. The research shows that the Saihanba ecological protection model has a positive reference effect for other regions in the country. Through the model calculation and analysis, it is found that China is positive for the realization of carbon neutralization. However, if some cities in China implement carbon neutralization at the current speed, they may not be able to achieve the goal of carbon neutralization, Therefore, through the verification of linear regression equation model, this paper puts forward some suggestions to improve the planting rate and strengthen the implementation of carbon neutralization policy.
