摘　　要：探究中原城市群生态环境效应演变机制,对中原城市群人地交互机制的研究与区域可持续发展具有重要的借鉴意义。基于2005、2010、2015和2020年的土地利用数据,以景观生态学和土地功能分类指数构建综合生态环境质量指数,并结合空间自相关分析、热点分析和生态贡献率,揭示中原城市群土地利用功能转化特征及生态环境的相应规律。结果表明:1)2005—2020年中原城市群农业生产空间占比64.96%,工矿生产空间和城镇生活空间土地利用动态度变化较大,分别增加10.99%和4.28%,林地生态空间变化速度最慢,为0.03%。2)2005—2020年中原城市群生态环境质量下降明显,整体上以较低质量区为主,占总面积的67%左右。低质量区以环状分布在边缘地区,高质量区和较高质量区呈现“三级、多核”的分布。3)2005—2020年中原城市群空间集聚性较为明显,以高高聚集和不显著为主,城镇与农村生活空间的不断扩大,使得低质量区面积不断扩张,冷点区域增加明显。4)2005—2020年生态质量改善和恶化趋势相互促进又彼此抑制,林地生态空间、草地生态空间转化为农业生产空间是生态环境质量恶化的主要原因。研究结果可为城市群经济发展和生态环境保护的耦合关系提供全新视角,持续推进区域可持续发展和加快生态文明建设的步伐。Exploring the evolution mechanism of eco-environmental effect in zhongyuan urban agglomerations has important practical significance for the study of human-land interaction mechanism and regional sustainable development.Based on the land use data of 2005,2010,2015 and 2020,a comprehensive ecological environment quality index was constructed by landscape ecology and land function classification index,and spatial autocorrelation analysis,hot spot analysis and ecological contribution rate were combined to reveal the characteristics of land use function transformation and the corresponding laws of ecological environment in zhongyuan urban agglomeration.The results show that:1)From 2005 to 2020,the agricultural production space accounted for 64.96%,the industrial and mining production space and urban living space had great changes in land use dynamic attitude,increasing by 10.99%and 4.28%,respectively,and the forest land ecological space had the slowest change rate of 0.03%.2)From 2005 to 2020,the eco-environment quality of the zhongyuan urban agglomerations decreased significantly,and the lower quality areas were the main areas on the whole,accounting for about 67%of the total area.The lowest quality areas were distributed in a ring pattern in the marginal areas,while the highest quality areas and higher quality areas showed a“three-pole and multi-core”distribution.3)From 2005 to 2020,the spatial agglomeration of zhongyuan urban agglomerations is relatively obvious,with high concentration and no significant concentration.The continuous expansion of urban and rural living land will lead to the continuous expansion of lowest quality areas and the obvious increase of cold spot areas.4)The improvement and deterioration of ecological quality from 2005 to 2020 promote and inhibit each other,and the conversion of woodland ecological space and grassland ecological space into agricultural production space is the main reason for the deterioration of eco-environment quality.The research results can provide a new perspective
