摘　　要：城市地区尤其是特大城市存在土地集约利用效率低下,生态空间、生产空间和生活空间失调等问题。以河南省郑州市为研究对象,利用1990—2019年4期土地利用数据,在构建“三生空间”分类体系的基础上,探讨了郑州市“三生空间”用地转型及其生态环境效应的时空变化规律。结果表明:(1)1990—2019年,生产与生态用地面积分别减少353.33、186.43 km^(2),生活用地面积增加539.76 km^(2),用地类型中转换面积最大的是农业生产用地,主要转换为城乡生活用地。(2)生产用地重心以东南向转移为主,生态用地重心迁移变化不大,生活用地重心东移3106 m。(3)郑州市生态环境质量呈现“西高东低”的格局,并于1990—2000年逐渐恶化,2000年以后生态环境恶化趋势在主城区外围持续蔓延,同时在中牟绿博园区和航空港区恶化明显。(4)郑州市同时存在着生态环境改善和恶化两种趋势,农业生产用地向城乡生活用地转移、水域和林地生态用地向农业生产用地转移是生态环境恶化的主要因素。There are someissues in urban areas,especially in mega-cities,such as low efficiency of intensive utilization,imbalance of ecological space,production space and living space.Taking Zhengzhou City,the capital of Henan Province as an example,this paper discussed the ecological-production-living spaces land use transformation and the temporal and spatial variation generation of environmental effects,based on the four phases of land use data from 1990 to 2019 and on the basis of building the classification system of ecological-production-living spaces.The results show that the area of production and ecological land use has been decreased by 353.33 km^(2) and 186.43 km^(2) respectively,and the area of domestic land use has been increased by 539.76 km^(2).Among the land use types,the largest amount of conversion is agricultural production land use,which is mainly converted to urban and rural living land use.During the study period,the center production land use mainly shifted to southeast.The center of ecological land use is moved not much,and the center of living land use is moved to the east of 3,106 m.The ecological environment quality of Zhengzhou City shows a pattern of“high in the west and low in the east”and is gradually deteriorated from 1990 to 2000.After 2000,it continues to spread in the periphery of the main urban area.The wetlands along the Yellow River and Shuanghe Lake to Yuanboyuan Park are the most improved areas in each period,showing a point distribution.There are two trends of ecological environment in Zhengzhou City:Improvement and deterioration,and the latter is much stronger than that of the former.The transfer of agricultural production land use to urban and rural living land use,water and forest land use to agricultural production land use are the two main factors of deterioration.
