title: Dataset on the Occupation of Cultivated Land Resources by 30m Resolution Construction Land Expansion in Changchun City (2005)
title: 长春市30m分辨率建设用地扩张对耕地资源的占用数据集（2005年）

description: a. Data content (data file/table name, including observation indicators)
This data includes a dataset of the impact of construction land expansion on arable land resources in Changchun City in 2005, 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 rational land use 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. At the same time, this area is a typical distribution area of black soil resources. The improvement of construction land utilization efficiency and the coordination of cultivated land protection are of great significance for regional sustainable development. The research results can provide data support and decision-making basis for the expansion planning of construction land in Changchun urban area and for achieving dynamic balance between construction land and cultivated land.
c. Service target
It can widely serve scientific researchers in related disciplines such as farmland protection and urban planning.
d. Time range of data
2005
e. The spatial scope of data
