| 受快速城镇化影响，生态功能区“三生空间”格局及其功能发生转变。以安徽省金寨县为例，基于2009年、 2014年和 2019年土地利用数据，对国土空间分类，采用景观格局指数、ArcGIS叠加分析方法，探究研究区“三生空 间”格局及用地功能时空演变特征，并利用灰色关联度模型揭示造成研究区“三生空间”格局演变的关键驱动因素。 结果表明：（1）金寨县“三生空间”分布格局在水平地域和垂直地域存在差异，生态空间广泛分布；生产空间主要分 布在北部、中部等地势平坦地区；生活空间呈散点状分布于生产、生态空间中。（2）用地结构与功能转型变化显著， 2014 ~ 2019年变化更加活跃。结构变化主要为生产空间减少，生态空间增加，生活空间波动减少；功能转型主要表 现为生产空间与生态空间相互转化，生活空间转出比例增加。（3）宏观政策、城镇化发展、产业发展及生态治理是 “三生空间”格局演变的重要驱动因素。 |

| The pattern and functions of the production-living-ecological (PLE) space in ecological functional areas are transforming due to rapid urbanization. Using land use data of Jinzhai County, Anhui Province in 2009, 2014 and 2019, the land spaces were classified, and the landscape pattern index as well as ArcGIS overlay analysis method were used to explore the spatial-temporal evolution characteristics of the PLE pattern and functions in the study area, and the gray correlation model was used to reveal the key driving factors that caused the evolution of the "production-living-ecological space" pattern in the study area. The results show that: (1) The distribution pattern of "production-living-ecological space" in Jinzhai County is different in horizontal and vertical regions. Ecological space is widely distributed, and production space is mainly distributed in flat areas such as the northern and central parts of the land. Living space is scattered in production and ecological space. (2) The transformation of land use structure and function has undergone significant changes, with more active changes from 2014 to 2019. The structural changes mainly include a decrease in production space, an increase in ecological space, and a decrease in fluctuations in living space; The main manifestation of functional transformation is the mutual transformation between production space and ecological space, with an increase in the proportion of living space transferred out. (3) Macro policies, urbanization development, industrial development, and ecological governance are important driving factors for the evolution of the“production-living-ecological space”pattern. |
