摘　　要：随着城镇化进程快速推进,国土空间功能格局产生剧烈演变,探讨国土空间“三生”功能的时空演化特征及影响因素,可为区域协调可持续发展和国土空间优化布局提供科学依据。该研究以河南省县域单元为例,从生产、生活、生态三个维度构建指标体系,评价区域2000、2006、2012年及2018年“三生”功能的空间格局特征及演化规律,并利用主成分分析法诊断“三生”功能演变的影响因素及作用机制。结果表明:1)2000—2018年河南省各县域“三生”功能均呈现不同程度的增长态势,空间上“三生”功能存在地域分异特征,生产功能空间梯度差异显著,生活功能由市辖区向外逐渐减弱,生态功能呈现“山地丘陵区>平原区>市辖区”的梯度变化;2)2000—2018年河南省“三生”功能发展变化明显,24.39%的县域生产功能明显减弱,86.99%的县域生活功能水平得到提升,而生态功能平稳发展,减弱区域较少;3)粮食保障、社会保障、生态维持是影响河南省“三生”功能演变的重要因素,经济发展与生态承载是基础性影响因素,说明不同影响因子间形成共同推力才能促进“三生”功能的良性发展。研究结果可为促进国土空间规划及空间可持续利用提供参考与依据。A land surface on Earth is an important space carrier for human survival,social and economic activities,as well as ecological civilization.The function pattern of land space has undergone some dramatic changes,with the rapid development of urbanization in recent years.Therefore,it is necessary to promote the orderly,moderate,and sustainable utilization of land space.Taking the county unit of Henan Province in China as an example,this study aims to explore the spatial-temporal evolution characteristics and influence factors of“production-living-ecological”functions(PLEFs)using the theoretical analysis.A PLEFs index system was also constructed to identify the land space pattern in 2000,2006,2012,and 2018 from the perspective of spatial function.A principal component analysis was then made to diagnose the impact factors and mechanism of PLEFs evolution,with an emphasis on the theoretical guidance and scientific basis for the regional sustainable development.The results show that:1)There were different degrees of growth for the PLEFs in the study area,when the entropy weight and GIS were performed on the spatial pattern characteristics and evolution of PLEFs in 2000,2006,2012,and 2018.More importantly,the PLEFs presented the regional differentiation in the land space.There was also a significant spatial gradient difference in production function.The living function was gradually weakened from the municipal area to the outside urban,where the ecological function showed a gradient change of“mountain hilly area>plain area>municipal area”.2)The evolution of PLEFs in the study area changed significantly from 2000 to 2018.Specifically,24.39%of the production function was significantly weakened,86.99%of the living function level was improved,whereas,the ecological function developed steadily,leading to the fewer weakened areas.3)The principal component analysis indicated that food security,social stability,and ecological maintenance were the important factors affecting the evolution of PLEFs in the study area.The ba
