Spatial-temporal Changes and Driving Factors of Cultivated Land Intensive Use in Inner Mongolia Autonomous Region from 1985 to 2018
[Objective] The spatial and temporal changes in the intensive use of arable land in Inner Mongolia Autonomous Region were studied in order to improve the intensive and sustainable use of arable land resources.[Methods] Principal component analysis was used to comprehensively evaluate the level of intensive use of arable land for the entire Inner Mongolia region and its 12 leagues
and to reveal its spatial and temporal variation characteristics and driving factors.[Results] ① The analysis conducted at the whole region level showed that the overall arable land intensification level increased during 1985-2018
with the arable land intensification level increasing from 63.30 to 88.12
an increase of 39.21%. The overall arable land intensification utilization showed a wave-like growth pattern. ② The spatial-level analysis showed that the level of intensive utilization of arable land in each league or city of Inner Mongolia could be divided into five levels by the natural division method
among which Bayannaoer and Hulun Buir League were classified as highly intensive (level Ⅰ); Xilingol League
Hing'an League
Alxa League
and Ordos City were relatively high intensive (level Ⅱ); Hohhot City was generally intensive (level Ⅲ); Chifeng and Tongliao City were relatively extensive (level Ⅳ). Wulanchabu City
Baotou City
and Wuhan City were extensive (level Ⅴ). ③ The analysis of drivers showed that GDP per capita
posable income per farmer
financial expenditures on agriculture
and the amount of investment in fixed assets in primary industries had significant positive driving effects on the intensive use of arable land in Inner Mongolia
while the gross value of primary industries
urbanization rate
and the area of water and soil management had significant negative driving effects on the intensive use of arable land in Inner Mongolia.[Conclusion] In the future
transfer of arable land should be regulated
the control of arable land use should be strengthened
the relationship between production and ecology should be coordinated
and the intensive use of arable land should be further improved.
