| 中文摘要: |
| 以苏州市2000—2020年土地利用数据为基础，构建“三生”空间适宜性评价指标体系，应用Pearson相关性分析与均方根误差系统解析“三生”空间适宜性的变化特征及影响因子。结果表明：2000—2020年苏州市生态空间占比大且变化稳定，2005—2010年城镇化加速，生产空间大幅转为生活空间，之后此趋势放缓至2020年；苏州市适宜性综合质量指数先升后降，高适宜区域在空间上由点状向面状发展，表现为南多北少；交通、城镇化率和坡度显著影响“三生”空间适宜性，第一产业占比、土地利用类型和PM25对适宜性影响较小；生产与生活空间指标高度相关，高程与其他指标相关性最低。 |
| 英文摘要: |
| Based on the land use data of Suzhou from 2000 to 2020， this study established an evaluation index system for the suitability of production living ecological spaces， analyzed the variation characteristics and influencing factors of the suitability of production living ecological spaces by applying Pearson correlation analysis and root mean square error(RMSE). The results indicated that from 2000 to 2020， the proportion of the ecological space in Suzhou was large and changed stably. From 2005 to 2010， the accelerated urbanization led to a significant transformation of production space into living space. This trend then slowed down until 2020. The comprehensive quality index of suitability in Suzhou rose first and then fell. The high suitability area developed from point like to area like in space， with more in the south and less in the north. Transportation， urbanization rate and slope significantly affected the suitability of the production living ecological spaces. The proportion of primary industry， land use type and PM25 concentration had relatively small influences on suitability. The indicators of production space and living space were highly correlated， while elevation had the lowest correlation with other indicators. |
