a.
Description
Data content (data file/table name, including observation indicators) This dataset includes the impact of construction land expansion on arable land resources in Changchun City in 2019, reflecting the spatiotemporal changes in construction land and arable land in Changchun City, as well as the impact of construction land expansion on arable land, providing reference for the rational use of land and arable land protection in black soil areas. b.
Construction purpose Rapid urbanization has made outstanding contributions in promoting industrialization and achieving economic and social transformation and development. However, at the same time, the disorderly development of urbanization has led to the expansion of construction land occupying a large amount of arable land, which has had a certain impact on the quantity, quality, and structure of arable land. Changchun City is the core area of economic development and urban expansion in Jilin Province.
