China has always attached great importance to respecting, protecting and restoring nature. The construction of the index system of Saihanba is an important part of exploring its impact on the ecological environment. In order to make the plantation closer to the natural forest, it is necessary to quantitatively evaluate the impact of Saihanba on the ecological environment. In this paper, air velocity, frequency / year of major pollution and air quality index are taken as direct impact indicators, and forest cover area and forest coverage as indirect indicators. The correlation coefficient between direct index and indirect index is calculated by correlation analysis method, the corresponding correlation coefficient matrix is listed, and the thermal map and column chart are made. Finally, according to the cluster analysis, the provinces are clustered every year, and the ecological model is established for the same kind of provinces. The correlation coefficient matrix is calculated according to the correlation coefficient formula, and the correlation coefficient matrix is drawn into a cluster diagram by using MATLAB.
