摘要
为推动黄河中游地区生态保护和高质量发展,提高土地资源利用综合效益,基于黄河中游地区2000—2020年的相关数据,利用土地利用转移矩阵、土地利用动态度评价、土地利用重心迁移模型等定量方法开展研究,分析黄河中游地区土地利用绿色转型的时空演变特征。结果表明,在研究期内,黄河中游地区农业生产用地面积持续减少,大量农业生产用地转化为林地生态用地和草地生态用地,重心分布在临汾市,迁移轨迹不明显;工矿生产用地面积持续增加,重心分布在临汾市且向东北方向偏移。林地、草地和水域生态用地面积总体上呈增长态势,其他生态用地面积呈下降趋势;黄河中游地区的草地生态用地和水域生态用地重心分布在临汾市中部,林地生态用地重心分布在运城市,3种用地类型偏移轨迹均不明显;其他生态用地重心先后落在吕梁市和临汾市。黄河中游地区的生活用地面积持续增加,城镇生活用地重心分布在临汾市南部,农村生活用地重心分布在运城市北部。
In order to promote ecological protection and high-quality development in the middle reaches of the Yellow River and improve the comprehensive benefits of land resource utilization,based on the relevant data of the middle reaches of the Yellow River from 2000 to 2020,quantitative methods such as land use transfer matrix,land use dynamic degree evaluation and land use gravity center migration model were used to analyze the spatial and temporal evolution characteristics of land use green transformation in the middle reaches of the Yellow River.The results showed that,during the study period,the area of agricultural land in the middle reaches of the Yellow River continued to decrease,with a large amount of agricultural land transformed into forest ecological land and grassland ecological land.The gravity center of agricultural land was distributed in Linfen City,and the migration trajectory was not obvious.The area of industrial production land continued to increase,and the gravity center was distributed in Linfen City and tended to move northeast.The area of forest ecological land,grass ecological land and water ecological land showed an overall growth trend,while the area of other ecological land showed a downward trend.The gravity center of grass ecological land and water ecological land was distributed in the central part of Linfen City,the gravity center of forest ecological land was distributed in Yuncheng City,and the migration trajectories of the three types of ecological land were not obvious.The gravity center of other ecological land in the early and late stages fell in Lyuliang City and Linfen City respectively.The area of living land in the middle reaches of the Yellow River continued to increase,and the gravity center of urban living land was distributed in the southern part of Linfen City,while the gravity center of rural living land was distributed in the northern part of Yuncheng City.
