摘　　要：为提高杭州都市圈国土空间开发和生态环境质量协调水平,推动国土空间高质量发展,采用综合评价法测度了2000—2020年杭州都市圈国土空间开发强度与生态质量水平,通过耦合协调度模型及空间自相关分析探索二者耦合协调度时空关联格局,通过OLS和地理加权回归(GWR)揭示影响因素。结果显示:(1)2000—2020年,杭州都市圈国土空间开发强度具有明显的“圈层—轴线”结构特征,呈现自东北向西南梯度下降趋势,而生态质量时空格局与之相反,并且年均生态质量值呈减小趋势。(2)2000—2020年,杭州都市圈国土空间开发强度与生态质量整体处于濒临失调和勉强协调等级,需要进一步平衡开发与保护之间的关系。(3)二者耦合协调度呈现显著的空间正相关关系,随着时间的推移,空间集聚有所减弱。(4)都市圈东北部等经济优势良好的区域具有较高的耦合协调水平,并且是主要的高-高集聚类型区。(5)自然因素与区位条件是影响国土空间开发与生态质量耦合协调关系的主导因子。综上所述,杭州都市圈需要充分发挥东北部核心圈层经济扩散效应,同时优化国土空间开发方式,严守国土空间开发底线。To improve the coordination level between the development of national land space and ecological environment quality in the Hangzhou metropolitan area,and promote high-quality development of national land space.In this paper,a comprehensive evaluation method was used to measure the level of land spatial development intensity and ecological environment quality in Hangzhou metropolitan area from 2000 to 2020,based on which,the temporal and spatial correlation pattern of the coupling coordination degree was explored through the coupling coordination degree model and the spatial autocorrelation analysis,and then the influencing factors were revealed through the OLS and geographically weighted regression(GWR).The results showed that:(1)the overall spatial development intensity and ecological quality of the Hangzhou metropolitan area from 2000 to 2020 were on the verge of being out of harmony and barely harmonized,and the relationship between development and protection needed to be further balanced.(2)The degree of coordination between the two couplings showed a significant positive spatial correlation,and the spatial agglomeration was weakened with the passage of time.(3)Regions with good economic advantages,such as the northeast of the metropolitan area,had a higher coupling coordination level and were the main high-high agglomeration type areas.(4)Natural factors and location conditions were the dominant factors influencing the coupled and coordinated relationship between national spatial development and ecological quality.In summary,the Hangzhou metropolitan area needs to fully leverage the economic diffusion effect of the core circle in the northeast,while optimizing the development of national land space and strictly adhering to the bottom line of national land space development.
