“三生”功能视角下广东省城市人居环境演变与机制

Evolution and Mechanism of Urban Human Settlement Environment in Guangdong Province from the Perspective of “Production-Living-Ecological” Functions

摘要: 改善城市人居环境是建设美丽中国的重要目标，也是衡量区域可持续发展的综合表征。从“生产–生活–生态”功能视角构建了广东省城市人居环境评价指标体系，运用空间分析和地理探测器方法，研究了2000~2020年广东省城市人居环境时空变化及其驱动机制，分析了影响城市人居环境的主要因素。研究发现：(1) 广东省城市人居环境总体为中等水平，中高水平城市数量先减后增而中低水平城市数量先增后减；(2) “三生”功能水平呈现差异化发展的空间变化格局，生产功能先减少后增加，生活功能持续增加，区域生态功能水平总体较高；(3) 生活功能和生产功能因子变化分别主导了2000~2010和2010~2020年广东省城市人居环境的变化，而生态功能因子的贡献相对较小。研究结果能为广东省制定城市规划和环境管理策略提供科学依据，有助于促进经济与生态保护的协调发展，实现人居环境可持续发展。

Abstract: Enhancing urban human settlements serves as a key objective for constructing a Beautiful China and a comprehensive indicator for assessing regional sustainable development. From the perspective of “production-living-ecological” (PLE) functions, this study establishes an evaluation index system for urban human settlements in Guangdong Province. Utilizing spatial analysis and the Geodetector method, we investigated the spatio-temporal evolution and driving mechanisms of urban human settlements in Guangdong from 2000 to 2020, identifying the primary influencing factors. The findings reveal that: (1) The overall urban human settlement environment in Guangdong Province was at a medium level, with the number of medium-high-level cities first decreasing and then increasing, while the number of medium-low-level cities first increased and then decreased. (2) The PLE functions exhibited spatially differentiated development patterns: production function first declined and then increased, living function continuously improved, and regional ecological function remained relatively high. (3) Changes in living and production functions were the dominant factors influencing the urban human settlement environment in Guangdong Province during 2000~2010 and 2010~2020, respectively, while the contribution of ecological function was relatively minor. The results provide a scientific basis for formulating urban planning and environmental management strategies in Guangdong, facilitating the coordinated development of economic growth and ecological conservation, and advancing the sustainable development of human settlements.
