This article mainly studies Saihanba's ecological model's advantages and characteristics and extends it to the whole country. Firstly, this article constructs a comprehensive evaluation model of fuzzy mathematics and evaluates that the impact on the environment before and after the restoration of Saihanba is very obvious. Secondly, the Pearson correlation coefficient model is established to obtain the correlation coefficient matrix between 10 indicators. Finally, the hypothesis test results deeply analyze the weak correlation between Saihanba and Beijing's ability to resist sandstorms. Then, perform the TOPSIS score evaluation of each province to complete the preliminary screening. The pixel overlay is used to analyze the domestic reasonable ecological area site selection for secondary screening. Finally, establishing an ecological protection area location model based on the immune algorithm determines that 9 regional ecological areas can be built, accounting for about 24.3% of the country's land area. It can absorb approximately 388.608*105KG of carbon dioxide and release 291.456*105KG of oxygen
