Analysis of Temporal and Spatial Changes in Land Use in Beijing Municipality Over the Past Two Decades

To better plan and use the land resources in the region and master the changes of land use types and their temporal and spatial distribution characteristics, this paper takes Beijing as an example, obtained land use data based on Landsat remote sensing images, and studied the temporal and spatial changes of land use in Beijing from land use dynamics and land use state index in recent 20 years. The results indicate that the distribution of land use types in Beijing is mainly dominated by arable land, forest land, construction land, and grassland. In the past 20 years, urban development has been rapid, construction land has been continuously increasing, and there is a trend of arable land transferring to construction land.With the increase of population, economic development, and the improvement of urbanization level, the internal industrial structure adjustment of agriculture and urbanization.The expansion of rural construction land will lead to the occupation of a large amount of arable land, and the contradiction between more people and less land will further intensify. Protecting arable land should be given more extensive attention.
