Abstract: The spatio-temporal patterns of territorial space development intensity in Inner Mongolia in the past 30 years (1990—2020) are investigated by integrating geographical national data and land use/cover data with a 30 m resolution. Then, the changes in territorial space were compared before and after the implementation of major function-oriented zoning. The impact of the major function-oriented zones on their main components is evaluated further. The results indicated that the intensity of territorial space development in Inner Mongolia showed a trend from the acceleration of 1990—2010 to the slowdown of growth in 2010—2020. The area of artificial construction land has expanded by 42% in the past 30 years. The increase in artificial construction land and agricultural land has reduced the amount of natural land. Since the implementation of major function-oriented zoning, the area of artificial construction land within the key development zone has increased. The area of agricultural land in the main producing zone for agricultural products changed from growth to reduction. The natural land area in the key ecological function zone declined. The outcomes are crucial for achieving the goals of “Beautiful Inner Mongolia” and advancing regional ecological civilization.

Key words: territorial space development intensity, territorial space pattern, major function-oriented zones, key ecological functional zone, land use change
