Using the four phase remote sensing image data sources of Zhengzhou from 2000 to 2020, the land use type map is obtained by preprocessing and supervised classification interpretation through ENVI software. The area is tabulated and the transfer matrix is calculated by ArcGIS software. The mutual transformation of land use types in Zhengzhou in recent 20 years is obtained, which is characterized by the highest and decreasing proportion of cultivated land and the increase of construction land and forest land. By counting the area of each part of the land type, this paper analyzes the changes of land use types in each part of Zhengzhou from 2000 to 2020. The results show that: (1) during 2000 to 2020, the area of construction land in the research area of Zhengzhou increased significantly, indicating that the project investment in the early stage is very large; the area of cultivated land decreased significantly, followed by the area of grassland, and the area of unused land decreased less than the first two; the water area shows a small increase after the decrease, but on the whole, the water area is still decreasing. This shows that in the process of urban development, the most cultivated land is occupied, but in the later stage, we began to realize the importance of ecosystem and take corresponding measures. (2) The area of forest land has increased significantly, indicating that Zhengzhou has paid attention to forest land protection, strengthened land acquisition and land expropriation, strictly prohibited logging and illegal use, minimized the occupation of forest land by various construction projects, vigorously developed inefficient forest land resources, accelerated the restoration of cultivated land and sparse forest construction, effectively developed forest land resources and gave full play to the ecological benefits of forest land.
