| 摘 要： | 黄河流域是生态保护与高质量发展战略的实行区域,评价可利用土地资源对黄河流域国土空间规划和高质量发展具有重要意义。该研究基于1990—2020年遥感影像数据,提取土地利用、DEM、坡度信息,运用后备可利用土地资源评价法,以济南市为例,探讨了近30年后备可利用土地资源时空演变趋势,分析了不同地域下后备土地利用资源用途的地域导向。结果表明:(1)济南市后备适宜建设用地面积为292.48 km2,主要分布在济南市的南部地区,面积呈下降趋势; 其中,历城区和长清区后备建设用地潜力最高,天桥区、历城区、市中区后备建设用地面积变化显著,分别为13.97 km2,-13.84 km2,-9.66 km2。(2)济南市后备耕地潜力较大(360.67 km2),空间分布格局与后备建设用地相似,其变化幅度依次为历城区、天桥区、市中区、长清区、槐荫区、历下区,其中历城区和长清区后备耕地潜力最高。(3)基于两类用地的重叠性与差异性,结合济南市的社会经济发展情况和自然环境条件状况进行分析,研究表明济南市天桥区南部、长清区与槐荫区北部衔接地带、市中区、历下区的后备土地资源可转化为建设用地。历城区中南部、长清区中部和东南地区的后备土地资源未来可转化为新增耕地。

| Abstract: | The Yellow River Basin is the implementation area of ecological protection and high-quality development strategy. The evaluation of available land resources is of great significance to the territorial and spatial planning and high-quality development in the Yellow River Basin. Based on the remote sensing data from 1990 to 2020 extracting land use data, DEM and slope information, using reserve available land resource evaluation method, exploring the temporal and spatial evolution trend of reserve available land resources along the Yellow River in Jinan City during the past 30 years, analyzing the regional orientation of the use of reserve land resources in different regions. The results indicate that:(1)the reserve suitable construction land area in Jinan City was 292.48 km2 and was decreasing and mostly in the southern part of the study area, among which Licheng District and Changqing District had the highest reserve construction land potential, and the area of reserved construction land in Tianqiao, Licheng, and Shizhong Districts had significantly changed, the area change was 13.97 km2, -13.84 km2, -9.66 km2, respectively;(2)Jinan City had the large potential of reserved cultivated land(360.67 km2), and the spatial distribution pattern was similar to the reserved construction land; the changing magnitude decreased in the order: Licheng, Tianqiao, Shizhong, Changqing, Huaiyin, and Lixia Districts, among which Licheng and Changqing Districts had the highest reserve cultivated land potential;(3)based on the overlap and differences of the two types of land, and regional socio-economic development and natural environmental conditions, it can be seen that the reserve land resources in the southern Tianqiao District, Changqing District and northern Huaiyin District, Shizhong District, and Lixia District of Jinan City can be converted into construction land, and the reserve land resources in the central and southern parts of Licheng District and the central and southeastern parts of Changqing District can be converted into new cultivated land. |
