| 中文摘要: |
| 基于2000—2020年青海省河湟地区5期土地利用数据，运用景观格局指数、土地利用转移矩阵和冗余分析（RDA）法分析河湟地区“三生”空间的时空演变过程和特征，并对可能引起该地区“三生”空间变化的影响因素进行探究。结果表明：河湟地区“三生”空间以生态空间为主，占比约8593%，生产空间次之，占比约1272%，生活空间最少，占比为135%；近20年间，河湟地区生活空间不断扩张，挤压着生产空间和生态空间，致使生产和生态空间呈破碎化发展；自然因素决定河湟地区“三生”空间的分布格局，人口和经济影响该区“三生”空间格局与功能的演变，政策因素对该区的人口和经济有着显著的推动和导向作用。 |

| Based on the land use data of five periods from 2000 to 2020 in Hehuang area in Qinghai， this paper analyzed the spatiotemporal evolution process and characteristics of “production living ecological” spaces in Hehuang area by using landscape pattern index， land use transfer matrix and redundancy analysis （RDA）， and the influencing factors that might cause the changes in “production living ecological” spaces. The results showed that the ecological space in Hehuang area dominated in “production living ecological” spaces， accounting for 85.93%， production space came second， accounting for 12.72%， and living space was the least， accounting for 1.35%. In the past 20 years， the continuous expansion of living space in Hehuang area squeezed production and ecological spaces， leading to their fragmented development. Natural factors determined the distribution pattern of “production living ecological” spaces in Hehuang area. Population and economy influenced the evolution of patterns and functions 〖GK!86mm〗of “production living ecological” spaces. Policies had a significant promoting and guiding effect on population and economy of this area. |
