Monitoring of Land Use Change in Shijiazhuang City Based on Remote Sensing Data

Abstract

With the rapid development of cities, urban land use monitoring has become the focus of increasing attention. In order to monitor the change of land use in Shijiazhuang City, the Sentinel-2 remote sensing data images from 2019 to 2022 were selected, processed by supervised classification and analyzed for dynamic changes. The result shows: the area of building land has shown an increasing trend, and the proportion of cultivated land occupied by urban expansion is the highest, and the change is most obvious in the city center; forest area increased; rivers show a tendency to expand, and the rivers represented by the Hutuo River have the most obvious changes. During the four-year period, the center of gravity of the city has changed, and the center of gravity of the city will move to the southwest in 2019-2020; the center of gravity of the city moves to the north from 2019 to 2022. Relevant land use changes can provide important references for urban development planning.
