| 摘要: |
| 【目的】分析1995—2020年包头市土地利用程度的时空变化及其驱动力。【方法】以包头市为研究区，运用土地利用转移矩阵、土地利用程度指数、地理探测器分析1995—2020年土地利用结构变化、包头市各区的土地利用程度指数以及DEM、坡度、坡向、土壤类型、气温、降水量和国内生产总值（GDP）等8类因子的驱动作用。【结果】1995—2020年，包头市以草地、耕地为主要用地类型，耕地主要转为草地和建设用地，转出面积分别为1 204.54 km2和315.4 km2，建设用地面积逐年增加。包头市土地利用程度指数在研究期间介于201~386，最高值出现在2020年的昆都仑区，最低值出现在2015年的白云鄂博矿区。人口密度和GDP是包头市土地利用程度变化的主要驱动因子，人口密度与坡向的交互作用解释力最高，对土地利用程度的交互影响大于其单因子。【结论】本研究揭示了包头市土地利用程度时空演变规律及驱动力因子，为包头市优化土地利用布局和生态-经济协调发展提供了科学依据。 |

| Abstract: |
| 【Objective】Baotou, located in the semi-arid region of Inner Mongolia, is characterized by intensive resource exploitation and rapid urbanization. It is facing increasing pressure on land use and ecological sustainability. This paper analyzed the spatiotemporal changes in land use and their driving forces from 1995 to 2020 in the region.【Method】A land use transfer matrix, land use intensity index, and GeoDetector model were employed to examine the changes in land use, spatial variation in land use intensity across the region, and the effects of eight factors on these changes: DEM, slope, aspect, soil type, temperature, precipitation, GDP, and population density.【Result】From 1995 to 2020, grassland and cultivated land were the predominant land use types in Baotou. Cultivated land was mainly converted to grassland and construction land, with transferred areas being 1 204.54 km2 and 315.4 km2, respectively; construction land had expanded continuously. The land use intensity index ranged from 201 to 386 during the study period, with the highest value observed in Kundulun District in 2020 and the lowest in Baiyun’ebo Mining District in 2015. Population density and GDP were the primary factors driving the changes in land use intensity. The interaction between population density and aspect had the strongest explanatory power, and their combined effect was greater than that of any single factor.【Conclusion】The identified spatiotemporal patterns and driving mechanisms of land use intensity in Baotou provide a scientific basis for optimizing land use and promoting coordinated ecological and economic development in the region. |
