| 以中原城市群核心发展区为研究对象，选取1980—2020年间4期遥感影像解译数据，结合DEM数据和SPOT-5高分影像数据,从数量、结构和空间布局等方面对中原城市群“三生”功能识别及时空演化展开分析。结果表明，40年来农业生产用地、牧草和其他生态用地面积大幅减少，城镇和乡村生活用地、工矿生产用地增长较快。城镇和乡村生活用地及农业生产用地的空间分布对人类社会经济活动影响较大。研究区内159个区县“三生”空间演化存在显著差异，以农业生产用地转生活用地、生态用地转农业生产用地两种转移类型最为显著。此外，农业生产用地转生态用地及生活用地转农业生产用地占比也较高。 |

| Taking the core development area in the Central Plains Urban Agglomeration as the research object, this paper selected four periods of remote sensing image interpretation data from 1980 to 2020, combined with DEM data and SPOT-5 high resolution image data, analyzed the function identification and spatiotemporal evolution of “ecological-production-living” of the Central Plains Urban Agglomeration from the aspects of quantity, structure and spatial layout. Results showed that the area of agricultural production land, pasture and other ecological land had decreased significantly in the past 40 years, and land for urban and rural living, industrial and mining production increased rapidly. The spatial distribution of land for urban and rural living and agricultural production had great impact on human social and economic activities. There were significant differences in the spatial evolution of “ecological-production-living” in 159 districts and counties in the study area. The most significant transfer types were agricultural production land to living land and ecological land to agricultural production land. In addition, the proportion of agricultural production land to ecological land and living land to agricultural production land was relatively high. |
