Using remote sensing images to analyze the land use changes in Beibei District, Chongqing City

The rapid urban development and the continuous growth of the population have led to an increasing amount of construction land, resulting in a continuous change in land use types. Land use changes can directly reflect the regional ecological environment and economic development situation, and the analysis of land use types has a very important guiding role and reference value for future urban construction and development planning. This study takes Beibei District of Chongqing as the research area, and uses Geographic Information System (GIS) and Remote Sensing (RS) technologies to analyze the land use changes in the region, with the aim of providing reference value for urban ecological environment construction. From the analysis of the image inversion results, it can be seen that from 2001 to 2023, the total area of cultivated land and forest land in Beibei District decreased from 86% to 80%, while the construction land area has been increasing year by year, indicating that Beibei District has been continuously carrying out urbanization construction over the past two decades. However, with the expansion of the urbanization process, Beibei District has also placed greater emphasis on green and low-carbon development, and improving the ecological environment quality has become an important part of Beibei District's future development.
