Abstract

In order to study the dynamic changes of vegetation cover in saihanba mechanical forest farm in the past 30 years, this paper used the Landsat remote sensing images of the area in 1989, 2001 and 2016 provided by the geospatial data cloud platform, and extracted the vegetation coverage information of saihanba mechanical forest farm with normalized vegetation index and pixel dichotomy, and analyzed the dynamic changes of vegetation cover in the three periods. Results show that fr om 1989 to 2001, mechanical sihanba forest vegetation cover age as a whole is in a state of slow wave growth, the western region is relatively stable, relatively obvious growth in central China, the eastern region has no obvious change. From 2001 to 2016, the FVC of this region has been significantly increased, especially in the western region where the FVC has been transformed from very low to very high FVC.The comprehensive results show that the vegetation cover of saihanba mechanical forest farm has undergone earth-shaking changes through artificial afforestation, creating a green miracle from vast wasteland to green water and green mountains, and bringing great ecological and social benefits to human beings.
