Abstract

Urban green spaces provide very important environmental and social services. Their dynamic changes are driven by a combination of natural and socioeconomic factors. However, the coupling mechanism of these factors has not been systematically studied. In this study, we examined dynamic characteristics of green space in Guangzhou from different zoning perspectives and explored the regional heterogeneity of the individual and interactive effects of driving factors using the geographic detector. The results showed that (1) from 2000 to 2020, the annual change rate of green space area in the central area was more apparent than that in the suburban areas. The fragmentation of green space in the near suburbs had increased. (2) Changes in green space were influenced by the combination of topography, climate, and socioeconomic development. From 2010 to 2020, the expansion of built-up land and GDP growth gradually had a substantial effect on the change in green space in the central area and the near suburbs. (3) The q-values of the interaction detections of the geodetector showed that the explanatory power of most factor interactions exceeded that of individual factors. Green space in the central area was primarily influenced by the interaction of economic and built-up land expansion. In contrast, green space in the near suburbs was mainly influenced by the interaction of urban expansion and topography and climate. Green space in the far suburbs was mainly affected by climate factors and human activity intensity. The results and methods of this study can provide decision support for the zoning planning of urban green space system in other cities or regions.

分区视角下广州绿地的演变特征与驱动力

城市绿地提供非常重要的环境和社会服务。它们的动态变化是由自然和社会经济因素共同驱动的。然而，这些因素的耦合机制尚未得到系统研究。在本研究中，我们从不同的分区视角考察了广州绿地的动态特征，并利用地理检测器探讨了驱动因素的个体效应和交互效应的区域异质性。结果表明：(1) 从 2000 年到 2020 年，中心区绿地面积的年变化率比郊区更为明显。近郊区绿地的破碎化程度加剧。(2）绿地的变化受到地形、气候和社会经济发展的综合影响。从 2010 年到 2020 年，建设用地的扩张和 GDP 的增长逐渐对中心区和近郊区的绿地变化产生了实质性的影响。(3) 地理检测器交互作用检测的 q 值表明，大多数因子交互作用的解释力超过了单个因子的解释力。中心区绿地主要受经济扩张和建设用地扩张的交互影响。相比之下，近郊绿地主要受城市扩张与地形和气候的交互影响。远郊绿地主要受气候因素和人类活动强度的影响。本研究的结果和方法可为其他城市或地区的城市绿地系统分区规划提供决策支持。
