摘要: 快速城镇化进程导致生态系统服务功能日益下降,如何促进城市扩张和生态保护的协调、可持续发展成为热点话题。现有研究多采用相关性指标测度单期生态系统服务间协同权衡特征,较少兼顾动态关系识别与作用强度测定。以湖北省为例,测定2010、2020年两期产水、食物供给、生境质量和土壤保持4项生态系统服务,构建动态权衡协同度(DESTI)量化2010~2020年间生态系统服务变化量的权衡/协同关系的强度及方向,引入最优参数地理探测器识别自然与社会因子对其驱动机制。结果表明:(1)2010~2020年,除生境质量外,食物供给、土壤保持和产水3项生态系统服务功能均呈递增态势;(2)4项生态系统服务间动态协同权衡的强度和方向在空间上存在显著差异;(3)动态协同权衡度受自然因素(日照时数、降雨)和土地利用类型的驱动作用明显,自然经济交互作用也增强了协同权衡的空间差异。研究全方位明晰了区域动态协同权衡的空间特征、作用强度与驱动机制,提出的管控措施有助于区域生态经济的协同发展。

Abstract: Rapid urbanization has led to an decline in ecosystem servicest a hot topic on how to promote the coordination and sustainable development between urban expansion and ecological protection. studies use correlation indicators to measure the synergistic trade-offs between ecosystem services in a single period, less attention to the identification of dynamic relationships and the determination of the impact intensity. Taking Hubei Province as an example, this study measure four ecosystem services, namely water yield, food supply, maintain biodiversity and soil conservation, for the 2010 and 2020he dynamic trade-off synergy index (DESTI) to quantify the strength and direction of trade-offs and synergistic relationships among ecosystem services between 2010 and 2020he optimal parameter geo-detector to identify the driving mechanisms of the natural socio-economic factors. The results showed that: (1) from 2010 to 2020, except for habitat quality, the food supply, soil conservation, and water yield all show an increasing trend; (2) there significant spatial differences in the strength and direction of the dynamic trade-offs among the four ecosystem services; (3) the dynamic synergistic trade-offs were significantly by natural factors (sunshine hours, rainfall) and land use types, while the natural-economic interactions also the synergistic relationships. Natural-economic interactions also enhanced the spatial differences in synergistic trade-offs. This study comprehensively clarifie the spatial characteristics, intensity and driving mechanism of regional dynamic synergistic trade-offs, and propose control measures that contribute to synergistic development of regional ecology and economy.
