[Objective] The aims of this study are to analyze the pattern of land use evolution and its driving factors in the sandy and coarse region of the middle reaches of the Yellow River, to explore the trend of regional land use change under different scenarios, and to provide a basis for guaranteeing regional ecological security and rational land use planning in the future. [Methods] Based on three phases of land use data in 2000, 2010 and 2020, the characteristics and driving forces of land use change in the sandy and coarse region of the middle reaches of the Yellow River were analyzed. Combined with multi-scenario setting, the PLUS model was used to predict the regional land use spatial pattern in 2030 under three different scenarios. [Results] The general trend of land use change in the study area during 2000—2020 was that cultivated land continued to decrease, forestland and grassland increased first and then decreased, water area and unused land decreased first and then increased, and construction land continued to increase. The PLUS model had a good effect on the driving force of regional land use change from 2000 to 2020, and the expansion of construction land was mainly affected by social and economic factors such as distance from county government, GDP and distance from railway. Under the natural development scenario, the area of cultivated land, forest land and grassland has decreased, while the area of water area, construction land and unused land has increased; under the economic construction scenario, construction land has increased significantly, which has a significant effect on the encroachment of other types of land; under the ecological protection scenario, the expansion of construction land has been effectively restricted, and the area is mainly transferred to grassland. The area of forestland, grassland and water area increases significantly, and the regional ecological land area increases significantly. [Conclusion] Under different development scenarios, the changes of land use pattern in the sandy and coarse region of the middle reaches of the Yellow River are significantly different. The future regional land use planning can refer to the research results and formulate policies according to the specific regional development goals, so as to ensure the ecological security and sustainable development of typical ecologically fragile areas.

[目的]分析黄河中游多沙粗沙区土地利用演变规律及其驱动因素, 探究不同情景下区域土地利用变化趋势, 以期为保障区域生态安全及未来土地利用合理规划提供依据。[方法]基于 2000 年、2010 年、2020 年 3 期土地利用数据, 进行黄河中游多沙粗沙区土地利用变化特征及驱动力分析, 并结合多情景设定, 利用 PLUS 模型预测了 2030 年3种不同情景下区域土地利用空间格局。[结果] 2000—2020 年研究区土地利用变化总体趋势体现为耕地持续减少, 林地、草地先增加后减少, 水域和未利用地先减少后增加, 建设用地持续增加; PLUS 模型对 2000—2020 年区域土地利用变化的驱动力挖掘效果较好, 其中建设用地的扩张受距县政府距离、GDP 和距铁路距离等社会经济因子影响为主; 自然发展情景下, 耕地、林地和草地面积有所下降, 水域、建设用地和未利用地的面积上升, 经济建设情景下, 建设用地大幅增加, 对其他各类用地侵占作用显著, 生态保护情景下, 建设用地扩张得到有效约束, 主要转入草地, 面积缩减。林地、草地和水域面积明显上升, 区域生态用地显著增加。[结论]不同发展情景下, 黄河中游多沙粗沙区土地利用格局变化差异显著, 区域未来土地利用规划应以可持续发展方式为导向, 结合具体发展目标制定政策, 注重典型生态脆弱区生态保护与经济建设的协调发展。 [ABSTRACT FROM AUTHOR] |
